CHAPTER 1
Introduction
1.1 Overview
This User’s Guide covers the following models: UAG2100, UAG4100 and UAG5100.
The UAG is a comprehensive service gateway. The UAG combines an IEEE 802.11n wireless access
point, router, 4-port switch and service gateway in one box. If you have a "statement printer", such
as SP350E, you can connect it directly to the UAG, allowing you to easily print subscriber
statements. The UAG is ideal for offices, coffee shops, libraries, hotels and airport terminals
catering to subscribers that seek Internet access. You should have an Internet account already set
up and have been given usernames, passwords etc. required for Internet access.
You can use web authentication to allow guests to access the network only after they authenticate
with the UAG through a specifically designated login web page. You can also forward the
authenticated client's e-mail messages to a specific SMTP server.
The UAG also provides bandwidth management, NAT, port forwarding, policy routing, DHCP server
and many other powerful features. The UAG’s security features include security policies and
certificates.

The UAG lets you set up multiple networks for your company. The UAG also provides two separate
LAN networks. You can set ports to be part of the LAN1 or LAN2.
1.2 Default Zones, Interfaces, and Ports
The default configurations for zones, interfaces, and ports are as follows. References to interfaces
may be generic rather than the specific name used in your model. For example, this guide may use
“the WAN interface” rather than “P1”.

Hardware Installation and Connection
2.1 Rack-mounting (UAG5100)
Use the following steps to mount the UAG on an EIA standard size, 19-inch rack or in a wiring closet
with other equipment using a rack-mounting kit. Make sure the rack will safely support the
combined weight of all the equipment it contains and that the position of the UAG does not make
the rack unstable or top-heavy. Take all necessary precautions to anchor the rack securely before
installing the unit.
Note: Leave 10 cm of clearance at the sides and 20 cm in the rear.
Use a #2 Phillips screwdriver to install the screws.
Note: Failure to use the proper screws may damage the unit.
1Align one bracket with the holes on one side of the UAG and secure it with the included bracket
screws (smaller than the rack-mounting screws).
2Attach the other bracket in a similar fashion.
3After attaching both mounting brackets, position the UAG in the rack and up the bracket holes with
the rack holes. Secure the UAG to the rack with the rack-mounting screws.

2.2 Wall Mounting (UAG2100 and UAG4100)
You may need screw anchors if mounting on a concrete or brick wall.
1Select a position free of obstructions on a wall strong enough to hold the weight of the device.
2Mark two holes on the wall at the appropriate distance apart for the screws.
Be careful to avoid damaging pipes or cables located inside the wall
when drilling holes for the screws.
3If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the
full depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way
in - leave a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the
screws all the way in - leave a gap of about 0.5 cm.
4Make sure the screws are fastened well enough to hold the weight of the UAG with the connection
cables.
5Align the holes on the back of the UAG with the screws on the wall. Hang the UAG on the screws.

1000Base-T Ports
The 1000Base-T auto-negotiating, auto-crossover Ethernet ports support 10/100/1000 Mbps
Gigabit Ethernet so the speed can be 100 Mbps or 1000 Mbps. The duplex mode is full at 1000
Mbps and half or full at 10/100 Mbps. An auto-negotiating port can detect and adjust to the
optimum Ethernet speed (10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the
connected device. An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-
through or crossover Ethernet cable. The factory default negotiation settings for the Ethernet ports
on the UAG are speed: auto, duplex: auto, and flow control: on (you cannot configure the flow
control setting, but the UAG can negotiate with the peer and turn it off if needed).
USB 2.0 Ports
Connect a USB storage device to a USB port on the UAG to archive the UAG system logs or save the
UAG operating system kernel to it.
Console Port (UAG5100)
Connect this port to your computer (using an RS-232 cable) if you want to configure the UAG using
the command line interface (CLI) via the console port.
For local management, you can use a computer with terminal emulation software configured to the
following parameters:
• VT100 terminal emulation
• 115200 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
Connect the male 9-pin end of the RS-232 console cable to the console port of the UAG. Connect

•Secure Gateway: Enter the WAN IP address or domain name of the remote IPSec device
(secure gateway) to identify the remote IPSec router by its IP address or a domain name.
•Pre-Shared Key: Type the password. Both ends of the VPN tunnel must use the same password.
Use 8 to 31 case-sensitive ASCII characters or 8 to 31 pairs of hexadecimal (“0-9”, “A-F”)
characters. Proceed a hexadecimal key with “0x”. You will receive a PYLD_MALFORMED (payload
malformed) packet if the same pre-shared key is not used on both ends.
•Local Policy (IP/Mask): Type the IP address of a computer on your network that can use the
tunnel. You can also specify a subnet. This must match the remote IP address configured on the
remote IPSec device.
•Remote Policy (IP/Mask): Type the IP address of a computer behind the remote IPSec device.
You can also specify a subnet. This must match the local IP address configured on the remote
IPSec device.

Application Scenario: This shows the scenario that the UAG supports.
•Site-to-site - The remote IPSec device has a static IP address or a domain name. This UAG can
initiate the VPN tunnel.
5.3.8 VPN Advanced Wizard - Phase 1 Settings
There are two phases to every IKE (Internet Key Exchange) negotiation – phase 1 (Authentication)
and phase 2 (Key Exchange). A phase 1 exchange establishes an IKE SA (Security Association).
Figure 53 VPN Advanced Wizard: Phase 1 Settings
•Secure Gateway: Any displays in this field if it is not configurable for the chosen scenario.
Otherwise, enter the WAN IP address or domain name of the remote IPSec device (secure
gateway) to identify the remote IPSec device by its IP address or a domain name. Use 0.0.0.0 if
the remote IPSec device has a dynamic WAN IP address.
•My Address (interface): Select an interface from the drop-down list box to use on your UAG.
•Negotiation Mode: Select Main for identity protection. Select Aggressive to allow more
incoming connections from dynamic IP addresses to use separate passwords.
Note: Multiple SAs connecting through a secure gateway must have the same negotiation
mode.
•Encryption Algorithm: 3DES and AES use encryption. The longer the key, the higher the
security (this may affect throughput). Both sender and receiver must use the same secret key,
which can be used to encrypt and decrypt the message or to generate and verify a message
authentication code. The DES encryption algorithm uses a 56-bit key. Triple DES (3DES) is a
variation on DES that uses a 168-bit key. As a result, 3DES is more secure than DES. It also
requires more processing power, resulting in increased latency and decreased throughput.
AES128 uses a 128-bit key and is faster than 3DES. AES192 uses a 192-bit key, and AES256
uses a 256-bit key.
•Authentication Algorithm: MD5 gives minimal security and SHA512 gives the highest
security. MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used to
authenticate packet data. The stronger the algorithm the slower it is.
Chapter 5 Quick Setup Wizards
UAG Series User’s Guide
76
•Key Group: DH5 is more secure than DH1 or DH2 (although it may affect throughput). DH1
(default) refers to Diffie-Hellman Group 1 a 768 bit random number. DH2 refers to Diffie-Hellman
Group 2 a 1024 bit (1Kb) random number. DH5 refers to Diffie-Hellman Group 5 a 1536 bit
random number.
•SA Life Time: Set how often the UAG renegotiates the IKE SA. A short SA life time increases
security, but renegotiation temporarily disconnects the VPN tunnel.
•NAT Traversal: Select this if the VPN tunnel must pass through NAT (there is a NAT router
between the IPSec devices).
Note: The remote IPSec device must also have NAT traversal enabled. See the help in the
main IPSec VPN screens for more information.
•Dead Peer Detection (DPD) has the UAG make sure the remote IPSec device is there before
transmitting data through the IKE SA. If there has been no traffic for at least 15 seconds, the
UAG sends a message to the remote IPSec device. If it responds, the UAG transmits the data. If
it does not respond, the UAG shuts down the IKE SA.
•Authentication Method: Select Pre-Shared Key to use a password or Certificate to use one
of the UAG’s certificates.
5.3.9 VPN Advanced Wizard - Phase 2
Phase 2 in an IKE uses the SA that was established in phase 1 to negotiate SAs for IPSec.
Figure 54 VPN Advanced Wizard: Phase 2 Settings
•Active Protocol: ESP is compatible with NAT, AH is not.
•Encapsulation: Tunnel is compatible with NAT, Transport is not.
•Encryption Algorithm: 3DES and AES use encryption. The longer the AES key, the higher the
security (this may affect throughput). Null uses no encryption.
•Authentication Algorithm: MD5 gives minimal security and SHA512 gives the highest
security. MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used to
authenticate packet data. The stronger the algorithm the slower it is.
•SA Life Time: Set how often the UAG renegotiates the IKE SA. A short SA life time increases
security, but renegotiation temporarily disconnects the VPN tunnel.

•Perfect Forward Secrecy (PFS): Disabling PFS allows faster IPSec setup, but is less secure.
Select DH1, DH2 or DH5 to enable PFS. DH5 is more secure than DH1 or DH2 (although it may
affect throughput). DH1 refers to Diffie-Hellman Group 1 a 768 bit random number. DH2 refers to
Diffie-Hellman Group 2 a 1024 bit (1Kb) random number. DH5 refers to Diffie-Hellman Group 5 a
1536 bit random number (more secure, yet slower).
•Local Policy (IP/Mask): Type the IP address of a computer on your network. You can also
specify a subnet. This must match the remote IP address configured on the remote IPSec device.
•Remote Policy (IP/Mask): Type the IP address of a computer behind the remote IPSec device.
You can also specify a subnet. This must match the local IP address configured on the remote
IPSec device.
•Nailed-Up: This displays for the site-to-site and remote access client role scenarios. Select this
to have the UAG automatically renegotiate the IPSec SA when the SA life time expires.

•Pre-Shared Key: VPN tunnel password.
•Certificate: The certificate the UAG uses to identify itself when setting up the VPN tunnel.
•Local Policy: IP address and subnet mask of the computers on the network behind your UAG
that can use the tunnel.
•Remote Policy: IP address and subnet mask of the computers on the network behind the
remote IPSec device that can use the tunnel.
• Copy and paste the Configuration for Remote Gateway commands into another ZLD-based
UAG’s command line interface.
•Negotiation Mode: Main mode provides better security, while aggressive mode is faster.
•Encryption Algorithm: The key size and encryption algorithm to use in the IPSec SA. 3DES
and AES use encryption. The longer the AES key, the higher the security (this may affect
throughput). Null uses no encryption.
•Authentication Algorithm: The hash algorithm to use to authenticate packet data in the IPSec
SA. MD5 gives minimal security and SHA512 gives the highest security.
•Key Group: The Diffie-Hellman key group to use for encryption. DH5 is more secure than DH1
or DH2 (although it may affect throughput).
•Active Protocol:ESP is compatible with NAT, AH is not.
•Encapsulation: Tunnel is compatible with NAT, Transport is not.
• Click Save to save the VPN rule.

7.19.1 Regular Expressions in Searching IPSec SAs
A question mark (?) lets a single character in the VPN connection or policy name vary. For example,
use “a?c” (without the quotation marks) to specify abc, acc and so on.
Wildcards (*) let multiple VPN connection or policy names match the pattern. For example, use
“*abc” (without the quotation marks) to specify any VPN connection or policy name that ends with
“abc”. A VPN connection named “testabc” would match. There could be any number (of any type) of
characters in front of the “abc” at the end and the VPN connection or policy name would still match.
A VPN connection or policy name named “testacc” for example would not match.
A * in the middle of a VPN connection or policy name has the UAG check the beginning and end and
ignore the middle. For example, with “abc*123”, any VPN connection or policy name starting with
“abc” and ending in “123” matches, no matter how many characters are in between.
The whole VPN connection or policy name has to match if you do not use a question mark or
asterisk.

9.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Station / Wireless Client
A station or wireless client is any wireless-capable device that can connect to an AP using a wireless
signal.
Dynamic Channel Selection (DCS)
Dynamic Channel Selection (DCS) is a feature that allows an AP to automatically select the radio
channel upon which it broadcasts by scanning the area around it and determining what channels
are currently being used by other devices.
Load Balancing (Wireless)
Wireless load balancing is the process where you limit the number of connections allowed on an
wireless access point (AP) or you limit the amount of wireless traffic transmitted and received on it
so the AP does not become overloaded.

Select By Traffi c Level to balance network traffic based on the volume generated by the
stations connected to an AP.
Once the threshold is crossed (either the maximum station numbers or with network
traffic), then the AP delays association request and authentication request packets from
any new station that attempts to make a connection. This allows the station to
automatically attempt to connect to another, less burdened AP if one is available.
Max Station
Number Enter the threshold number of stations at which an AP begins load balancing its
connections.
Traffic Level Select the threshold traffic level at which the AP begins load balancing its connections
(low, medium, high).
Disassociate
station when
overloaded
Select this option to disassociate wireless clients connected to the AP when it becomes
overloaded. If you do not enable this option, then the AP simply delays the connection
until it can afford the bandwidth it requires, or it transfers the connection to another AP
within its broadcast radius.
The disassociation priority is determined automatically by the UAG and is as follows:
•Idle Timeout - Devices that have been idle the longest will be disassociated first. If
none of the connected devices are idle, then the priority shifts to Signal Strength.
•Signal Strength - Devices with the weakest signal strength will be disassociated first.
Note: If you enable this function, you should ensure that there are multiple APs within the
broadcast radius that can accept any rejected or kicked wireless clients; otherwise, a
wireless client attempting to connect to an overloaded AP will be kicked continuously
and never be allowed to connect.
Chapter 9 Wireless
UAG Series User’s Guide
147
9.5.1 Disassociating and Delaying Connections
When your AP becomes overloaded, there are two basic responses it can take. The first one is to
“delay” a client connection. This means that the AP withholds the connection until the data transfer
throughput is lowered or the client connection is picked up by another AP. If the client is picked up
by another AP then the original AP cannot resume the connection.
For example, here the AP has a balanced bandwidth allotment of 6 Mbps. If laptop R connects and
it pushes the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop’s connection
until it can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to
spare.
Figure 103 Delaying a Connection
The second response your AP can take is to kick the connections that are pushing it over its
balanced bandwidth allotment.

Figure 104 Kicking a Connection
Connections are kicked based on either idle timeout or signal strength. The UAG first looks to
see which devices have been idle the longest, then starts kicking them in order of highest idle time.
If no connections are idle, the next criteria the UAG analyzes is signal strength. Devices with the
weakest signal strength are kicked first.

This field is available only when you set 2.4 GHz Channel Selection Method to auto.
Select Three-Channel Deployment to limit channel switching to channels 1,6, and
11, the three channels that are sufficiently attenuated to have almost no impact on one
another. In other words, this allows you to minimize channel interference by limiting
channel-hopping to these three “safe” channels.
Select Four-Channel Deployment to limit channel switching to four channels.
Depending on the country domain, if the only allowable channels are 1-11 then the UAG
uses channels 1, 4, 7, 11 in this configuration; otherwise, the UAG uses channels 1, 5,
9, 13 in this configuration. Four channel deployment expands your pool of possible
channels while keeping the channel interference to a minimum.

9.8 Technical Reference
The following section contains additional technical information about the features described in this
chapter.
9.8.1 Dynamic Channel Selection
When numerous APs broadcast within a given area, they introduce the possibility of heightened
radio interference, especially if some or all of them are broadcasting on the same radio channel. If
the interference becomes too great, then the network administrator must open his AP configuration
options and manually change the channel to one that no other AP is using (or at least a channel
that has a lower level of interference) in order to give the connected stations a minimum degree of
interference. Dynamic channel selection frees the network administrator from this task by letting
the AP do it automatically. The AP can scan the area around it looking for the channel with the least
amount of interference.
In the 2.4 GHz spectrum, each channel from 1 to 13 is broken up into discrete 22 MHz segments
that are spaced 5 MHz apart. Channel 1 is centered on 2.412 GHz while channel 13 is centered on
2.472 GHz.
Figure 107 An Example Three-Channel Deployment
Three channels are situated in such a way as to create almost no interference with one another if
used exclusively: 1, 6 and 11. When an AP broadcasts on any of these three channels, it should not
interfere with neighboring APs as long as they are also limited to same trio.
Figure 108 An Example Four-Channel Deployment
However, some regions require the use of other channels and often use a safety scheme with the
following four channels: 1, 4, 7 and 11. While they are situated sufficiently close to both each other
and the three so-called “safe” channels (1,6 and 11) that interference becomes inevitable, the
severity of it is dependent upon other factors: proximity to the affected AP, signal strength, activity,
and so on.
Chapter 9 Wireless
UAG Series User’s Guide
153
Finally, there is an alternative four channel scheme for ETSI, consisting of channels 1, 5, 9, 13. This
offers significantly less overlap that the other one.
Figure 109 An Alternative Four-Channel Deployment
9.8.2 Load Balancing
Because there is a hard upper limit on an AP’s wireless bandwidth, load balancing can be crucial in
areas crowded with wireless users. Rather than let every user connect and subsequently dilute the
available bandwidth to the point where each connecting device receives a meager trickle, the load
balanced AP instead limits the incoming connections as a means to maintain bandwidth integrity.
There are two kinds of wireless load balancing available on the UAG:
Load balancing by station number limits the number of devices allowed to connect to your AP. If
you know exactly how many stations you want to let connect, choose this option.
For example, if your company’s graphic design team has their own AP and they have 10 computers,
you can load balance for 10. Later, if someone from the sales department visits the graphic design
team’s offices for a meeting and he tries to access the network, his computer’s connection is
delayed, giving it the opportunity to connect to a different, neighboring AP. If he still connects to
the AP regardless of the delay, then the AP may boot other people who are already connected in
order to associate with the new connection.
Load balancing by traffic level limits the number of connections to the AP based on maximum
bandwidth available. If you are uncertain as to the exact number of wireless connections you will
have then choose this option. By setting a maximum bandwidth cap, you allow any number of
devices to connect as long as their total bandwidth usage does not exceed the configured
bandwidth cap associated with this setting. Once the cap is hit, any new connections are rejected or
delayed provided that there are other APs in range.
Imagine a coffee shop in a crowded business district that offers free wireless connectivity to its
customers. The coffee shop owner can’t possibly know how many connections his AP will have at
any given moment. As such, he decides to put a limit on the bandwidth that is available to his
customers but not on the actual number of connections he allows. This means anyone can connect
to his wireless network as long as the AP has the bandwidth to spare. If too many people connect
and the AP hits its bandwidth cap then all new connections must basically wait for their turn or get
shunted to the nearest identical AP.

CHAPTER 10
Interfaces
10.1 Interface Overview
Use the Interface screens to configure the UAG’s interfaces. You can also create interfaces on top
of other interfaces.
•Ports are the physical ports to which you connect cables.
•Interfaces are used within the system operationally. You use them in configuring various
features. An interface also describes a network that is directly connected to the UAG. For
example, You connect the LAN network to the LAN interface.
•Zones are groups of interfaces used to ease security policy configuration.
10.1.1 What You Can Do in this Chapter
•Use the Port Role screen (Section 10.2 on page 156) to create port groups and to assign
physical ports and port groups to Ethernet interfaces.
•Use the Ethernet screens (Section 10.3 on page 157) to configure the Ethernet interfaces.
Ethernet interfaces are the foundation for defining other interfaces and network policies.
•Use the PPP screens (Section 10.4 on page 168) for PPPoE or PPTP Internet connections.
•Use the VLAN screens (Section 10.5 on page 174) to divide the physical network into multiple
logical networks. VLAN interfaces receive and send tagged frames. The UAG automatically adds
or removes the tags as needed. Each VLAN can only be associated with one Ethernet interface.
•Use the Bridge screens (Section 10.6 on page 181) to combine two or more network segments
into a single network.
•Use the Virtual Inte rface screen (Section 10.7.1 on page 190) to create virtual interfaces on
top of Ethernet interfaces to tell the UAG where to route packets. You can create virtual Ethernet
interfaces, virtual VLAN interfaces, and virtual bridge interfaces.
•Use the Trunk screens (Chapter 11 on page 195) to configure load balancing.
10.1.2 What You Need to Know
Interface Characteristics
Interfaces generally have the following characteristics (although not all characteristics apply to each
type of interface).
• An interface is a logical entity through which (layer-3) packets pass.
• An interface is bound to a physical port or another interface.
• Many interfaces can share the same physical port.
• An interface belongs to at most one zone.
• Many interfaces can belong to the same zone.
Chapter 10 Interfaces
UAG Series User’s Guide
155
• Layer-3 virtualization (IP alias, for example) is a kind of interface.
Types of Interfaces
You can create several types of interfaces in the UAG.
• Setting interfaces to the same port role forms a port group. Port groups create a hardware
connection between physical ports at the layer-2 (data link, MAC address) level. Port groups are
created when you use the Interface > Port Roles screen to set multiple physical ports to be
part of the same interface.
•Ethernet interfaces are the foundation for defining other interfaces and network policies.
•VLAN interfaces receive and send tagged frames. The UAG automatically adds or removes the
tags as needed. Each VLAN can only be associated with one Ethernet interface.
•Bridge interfaces create a software connection between Ethernet or VLAN interfaces at the
layer-2 (data link, MAC address) level. Unlike port groups, bridge interfaces can take advantage
of some security features in the UAG. You can also assign an IP address and subnet mask to the
bridge.
•PPP interfaces support Point-to-Point Protocols (PPP). ISP accounts are required for PPPoE/PPTP
interfaces.
•Virtual interfaces provide additional routing information in the UAG. There are three types:
virtual Ethernet interfaces, virtual VLAN interfaces, and virtual bridge interfaces.
•Trunk interfaces manage load balancing between interfaces.
Port groups and trunks have a lot of characteristics that are specific to each type of interface. See
Section 10.2 on page 156 and Chapter 11 on page 195 for details. The other types of interfaces--
Ethernet, PPP, VLAN, bridge, and virtual--have a lot of similar characteristics. These characteristics
are listed in the following table and discussed in more detail below.
- * The format of interface names other than the Ethernet and ppp interface names is strict. Each name consists of 2-4
letters (interface type), followed by a number (x). For most interfaces, x is limited by the maximum number of the
type of interface. For VLAN interfaces, x is defined by the number you enter in the VLAN name field. For example,
Ethernet interface names are wan1, lan1, lan2; VLAN interfaces are vlan0, vlan1, vlan2, ...; and so on.
** - The names of virtual interfaces are derived from the interfaces on which they are created. For example, virtual
interfaces created on Ethernet interface wan1 are called wan1:1, wan1:2, and so on. Virtual interfaces created on

VLAN interface vlan2 are called vlan2:1, vlan2:2, and so on. You cannot specify the number after the colon(:) in the
Web Configurator; it is a sequential number. You can specify the number after the colon if you use the CLI to set up
a virtual interface.
Relationships Between Interfaces
In the UAG, interfaces are usually created on top of other interfaces. Only Ethernet interfaces are
created directly on top of the physical ports or port groups. The relationships between interfaces
are explained in the following table.
* - You cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface if the underlying interface is a
member of a bridge. You also cannot add an Ethernet interface or VLAN interface to a bridge if the member
interface has a virtual interface or PPP interface on top of it.

•See Chapter 11 on page 195 to configure load balancing using trunks.
10.2 Port Role Screen
To access this screen, click Configuration > Network > Interface > Port Role. Use the Port
Role screen to set the UAG’s flexible ports as part of the lan1, lan2 or dmz interfaces. This creates
a hardware connection between the physical ports at the layer-2 (data link, MAC address) level.
This provides wire-speed throughput but no security.

Note the following if you are configuring from a computer connected to a lan1, lan2 or dmz port
and change the port's role:
• A port's IP address varies as its role changes, make sure your computer's IP address is in the
same subnet as the UAG's lan1, lan2 or dmz IP address.
• Use the appropriate lan1, lan2 or dmz IP address to access the UAG.
Figure 110 Configuration > Network > Interface > Port Role
The physical Ethernet ports are shown at the top and the Ethernet interfaces and zones are shown
at the bottom of the screen. Use the radio buttons to select for which interface (network) you want
to use each physical port. For example, select a port’s lan1 radio button to use the port as part of
the lan1 interface. The port will use the UAG’s lan1 IP address and MAC address.
When you assign more than one physical port to a network, you create a port group. Port groups
have the following characteristics:
• There is a layer-2 Ethernet switch between physical ports in the port group. This provides wire-
speed throughput but no security.
• It can increase the bandwidth between the port group and other interfaces.
• The port group uses a single MAC address.

10.3 Ethernet Summary Screen
This screen lists every Ethernet interface and virtual interface created on top of Ethernet interfaces.
To access this screen, click Configuration > Network > Interface > Ethernet.
Unlike other types of interfaces, you cannot create new Ethernet interfaces nor can you delete any
of them. If an Ethernet interface does not have any physical ports assigned to it (see Section 10.2
Physical Ports
Interfaces
Chapter 10 Interfaces
UAG Series User’s Guide
158
on page 156), the Ethernet interface is effectively removed from the UAG, but you can still
configure it.
Ethernet interfaces are similar to other types of interfaces in many ways. They have an IP address,
subnet mask, and gateway used to make routing decisions. They restrict the amount of bandwidth
and packet size. They can provide DHCP services, and they can verify the gateway is available.
Use Ethernet interfaces to control which physical ports exchange routing information with other
routers and how much information is exchanged through each one. The more routing information is
exchanged, the more efficient the routers should be. However, the routers also generate more
network traffic, and some routing protocols require a significant amount of configuration and
management.

Figure 116 Example: PPPoE/PPTP Interfaces
PPPoE/PPTP interfaces are similar to other interfaces in some ways. They have an IP address,
subnet mask, and gateway used to make routing decisions; they restrict bandwidth and packet
size; and they can verify the gateway is available. There are two main differences between PPPoE/
PPTP interfaces and other interfaces.
• You must also configure an ISP account object for the PPPoE/PPTP interface to use.
Each ISP account specifies the protocol (PPPoE or PPTP), as well as your ISP account information.
If you change ISPs later, you only have to create a new ISP account, not a new PPPoE/PPTP
interface. You should not have to change any network policies.
• You do not set up the subnet mask or gateway.
PPPoE/PPTP interfaces are interfaces between the UAG and only one computer. Therefore, the
subnet mask is always 255.255.255.255. In addition, the UAG always treats the ISP as a
gateway.

10.5 VLAN Interfaces
A Virtual Local Area Network (VLAN) divides a physical network into multiple logical networks. The
standard is defined in IEEE 802.1q.
In this example, there are two physical networks and three departments A, B, and C. The physical
networks are connected to hubs, and the hubs are connected to the router.
Figure 119 Example: Before VLAN
Alternatively, you can divide the physical networks into three VLANs.
Figure 120 Example: After VLAN
Each VLAN is a separate network with separate IP addresses, subnet masks, and gateways. Each
VLAN also has a unique identification number (ID). The ID is a 12-bit value that is stored in the
MAC header. The VLANs are connected to switches, and the switches are connected to the router.
(If one switch has enough connections for the entire network, the network does not need switches
A and B.)

• Traffic inside each VLAN is layer-2 communication (data link layer, MAC addresses). It is handled
by the switches. As a result, the new switch is required to handle traffic inside VLAN 2. Traffic is
only broadcast inside each VLAN, not each physical network.
• Traffic between VLANs (or between a VLAN and another type of network) is layer-3
communication (network layer, IP addresses). It is handled by the router.
This approach provides a few advantages.
• Increased performance - In VLAN 2, the extra switch should route traffic inside the sales
department faster than the router does. In addition, broadcasts are limited to smaller, more
logical groups of users.
• Higher security - If each computer has a separate physical connection to the switch, then
broadcast traffic in each VLAN is never sent to computers in another VLAN.
• Better manageability - You can align network policies more appropriately for users. For example,
you can set different bandwidth limits for each VLAN (each department in the example above).
These rules are also independent of the physical network, so you can change the physical
network without changing policies.
In this example, the new switch handles the following types of traffic:
•Inside VLAN 2.
• Between the router and VLAN 1.
• Between the router and VLAN 2.
• Between the router and VLAN 3.
VLAN Interfaces Overview
In the UAG, each VLAN is called a VLAN interface. As a router, the UAG routes traffic between VLAN
interfaces, but it does not route traffic within a VLAN interface. All traffic for each VLAN interface
can go through only one Ethernet interface, though each Ethernet interface can have one or more
VLAN interfaces.
Note: Each VLAN interface is created on top of only one Ethernet interface.
Otherwise, VLAN interfaces are similar to other interfaces in many ways. They have an IP address,
subnet mask, and gateway used to make routing decisions. They restrict bandwidth and packet
size. They can provide DHCP services, and they can verify the gateway is available.

Bridge Overview
A bridge creates a connection between two or more network segments at the layer-2 (MAC
address) level. In the following example, bridge X connects four network segments.
When the bridge receives a packet, the bridge records the source MAC address and the port on
which it was received in a table. It also looks up the destination MAC address in the table. If the
bridge knows on which port the destination MAC address is located, it sends the packet to that port.
If the destination MAC address is not in the table, the bridge broadcasts the packet on every port
(except the one on which it was received).
In the example above, computer A sends a packet to computer B. Bridge X records the source
address 0A:0A:0A:0A:0A:0A and port 2 in the table. It also looks up 0B:0B:0B:0B:0B:0B in the
table. There is no entry yet, so the bridge broadcasts the packet on ports 1, 3, and 4.
If computer B responds to computer A, bridge X records the source address 0B:0B:0B:0B:0B:0B
and port 4 in the table. It also looks up 0A:0A:0A:0A:0A:0A in the table and sends the packet to
port 2 accordingly.
Bridge Interface Overview
A bridge interface creates a software bridge between the members of the bridge interface. It also
becomes the UAG’s interface for the resulting network.
This UAG can bridge traffic between some interfaces while it routes traffic for other interfaces. The
bridge interfaces also support more functions, like interface bandwidth parameters, DHCP settings,
and connectivity check. To use the whole UAG as a transparent bridge, add all of the UAG’s
interfaces to a bridge interface.

A bridge interface may consist of the following members:
• Zero or one VLAN interfaces (and any associated virtual VLAN interfaces)
• Any number of Ethernet interfaces (and any associated virtual Ethernet interfaces)
When you create a bridge interface, the UAG removes the members’ entries from the routing table
and adds the bridge interface’s entries to the routing table. For example, this table shows the
routing table before and after you create bridge interface br0 (250.250.250.0/23) between lan1
and vlan1.
In this example, virtual Ethernet interface lan1:1 is also removed from the routing table when lan1
is added to br0. Virtual interfaces are automatically added to or remove from a bridge interface
when the underlying interface is added or removed.

Virtual interfaces can be created on top of Ethernet interfaces, VLAN interfaces, or bridge
interfaces. Virtual VLAN interfaces recognize and use the same VLAN ID. Otherwise, there is no
difference between each type of virtual interface. Network policies (for example, security policy
control rules) that apply to the underlying interface automatically apply to the virtual interface as
well.
Like other interfaces, virtual interfaces have an IP address, subnet mask, and gateway used to
make routing decisions. However, you have to manually specify the IP address and subnet mask;
virtual interfaces cannot be DHCP clients. Like other interfaces, you can restrict bandwidth through
virtual interfaces, but you cannot change the MTU. The virtual interface uses the same MTU that the

10.8 Interface Technical Reference
Here is more detailed information about interfaces on the UAG.
IP Address Assignment
Most interfaces have an IP address and a subnet mask. This information is used to create an entry
in the routing table.
Figure 126 Example: Entry in the Routing Table Derived from Interfaces
For example, if the UAG gets a packet with a destination address of 100.100.25.25, it routes the
packet to interface lan1. If the UAG gets a packet with a destination address of 200.200.200.200, it
routes the packet to interface wan1.
In most interfaces, you can enter the IP address and subnet mask manually. In PPPoE/PPTP
interfaces, however, the subnet mask is always 255.255.255.255 because it is a point-to-point
interface. For these interfaces, you can only enter the IP address.
In many interfaces, you can also let the IP address and subnet mask be assigned by an external
DHCP server on the network. In this case, the interface is a DHCP client. Virtual interfaces,
however, cannot be DHCP clients. You have to assign the IP address and subnet mask manually.
In general, the IP address and subnet mask of each interface should not overlap, though it is
possible for this to happen with DHCP clients.

UAG Series User’s Guide
192
In the example above, if the UAG gets a packet with a destination address of 5.5.5.5, it might not
find any entries in the routing table. In this case, the packet is dropped. However, if there is a
default router to which the UAG should send this packet, you can specify it as a gateway in one of
the interfaces. For example, if there is a default router at 200.200.200.100, you can create a
gateway at 200.200.200.100 on wan1. In this case, the UAG creates the following entry in the
routing table.
The gateway is an optional setting for each interface. If there is more than one gateway, the UAG
uses the gateway with the lowest metric, or cost. If two or more gateways have the same metric,
the UAG uses the one that was set up first (the first entry in the routing table). In PPPoE/PPTP
interfaces, the other computer is the gateway for the interface by default. In this case, you should
specify the metric.
If the interface gets its IP address and subnet mask from a DHCP server, the DHCP server also
specifies the gateway, if any.
Interface Parameters
The UAG restricts the amount of traffic into and out of the UAG through each interface.
• Egress bandwidth sets the amount of traffic the UAG sends out through the interface to the
network.
• Ingress bandwidth sets the amount of traffic the UAG allows in through the interface from the
network.1
If you set the bandwidth restrictions very high, you effectively remove the restrictions.
The UAG also restricts the size of each data packet. The maximum number of bytes in each packet
is called the maximum transmission unit (MTU). If a packet is larger than the MTU, the UAG divides
it into smaller fragments. Each fragment is sent separately, and the original packet is re-assembled
later. The smaller the MTU, the more fragments sent, and the more work required to re-assemble
packets correctly. On the other hand, some communication channels, such as Ethernet over ATM,
might not be able to handle large data packets.
DHCP Settings
Dynamic Host Configuration Protocol (DHCP, RFC 2131, RFC 2132) provides a way to automatically
set up and maintain IP addresses, subnet masks, gateways, and some network information (such
as the IP addresses of DNS servers) on computers in the network. This reduces the amount of
manual configuration you have to do and usually uses available IP addresses more efficiently.
In DHCP, every network has at least one DHCP server. When a computer (a DHCP client) joins the
network, it submits a DHCP request. The DHCP servers get the request; assign an IP address; and
provide the IP address, subnet mask, gateway, and available network information to the DHCP
client. When the DHCP client leaves the network, the DHCP servers can assign its IP address to
another DHCP client.

Chapter 10 Interfaces
UAG Series User’s Guide

In the UAG, some interfaces can provide DHCP services to the network. In this case, the interface
can be a DHCP relay or a DHCP server.
As a DHCP relay, the interface routes DHCP requests to DHCP servers on different networks. You
can specify more than one DHCP server. If you do, the interface routes DHCP requests to all of
them. It is possible for an interface to be a DHCP relay and a DHCP client simultaneously.
As a DHCP server, the interface provides the following information to DHCP clients.
• IP address - If the DHCP client’s MAC address is in the UAG’s static DHCP table, the interface
assigns the corresponding IP address. If not, the interface assigns IP addresses from a pool,
defined by the starting address of the pool and the pool size.
The UAG cannot assign the first address (network address) or the last address (broadcast
address) in the subnet defined by the interface’s IP address and subnet mask. For example, in
the first entry, if the subnet mask is 255.255.255.0, the UAG cannot assign 50.50.50.0 or
50.50.50.255. If the subnet mask is 255.255.0.0, the UAG cannot assign 50.50.0.0 or
50.50.255.255. Otherwise, it can assign every IP address in the range, except the interface’s IP
address.
If you do not specify the starting address or the pool size, the interface the maximum range of IP
addresses allowed by the interface’s IP address and subnet mask. For example, if the interface’s
IP address is 9.9.9.1 and subnet mask is 255.255.255.0, the starting IP address in the pool is
9.9.9.2, and the pool size is 253.
• Subnet mask - The interface provides the same subnet mask you specify for the interface. See IP
Address Assignment on page 191.
• Gateway - The interface provides the same gateway you specify for the interface. See IP Address
Assignment on page 191.
• DNS servers - The interface provides IP addresses for up to three DNS servers that provide DNS
services for DHCP clients. You can specify each IP address manually (for example, a company’s
own DNS server), or you can refer to DNS servers that other interfaces received from DHCP
servers (for example, a DNS server at an ISP). These other interfaces have to be DHCP clients.
It is not possible for an interface to be the DHCP server and a DHCP client simultaneously.
WINS
WINS (Windows Internet Naming Service) is a Windows implementation of NetBIOS Name Server
(NBNS) on Windows. It keeps track of NetBIOS computer names. It stores a mapping table of your
network’s computer names and IP addresses. The table is dynamically updated for IP addresses
assigned by DHCP. This helps reduce broadcast traffic since computers can query the server instead
of broadcasting a request for a computer name’s IP address. In this way WINS is similar to DNS,
although WINS does not use a hierarchy (unlike DNS). A network can have more than one WINS
server. Samba can also serve as a WINS server.

PPPoE/PPTP Overview
Point-to-Point Protocol over Ethernet (PPPoE, RFC 2516) and Point-to-Point Tunneling Protocol
(PPTP, RFC 2637) are usually used to connect two computers over phone lines or broadband
connections. PPPoE is often used with cable modems and DSL connections. It provides the following
advantages:
• The access and authentication method works with existing systems, including RADIUS.
• You can access one of several network services. This makes it easier for the service provider to

• PPPoE does not usually require any special configuration of the modem.
PPTP is used to set up virtual private networks (VPN) in unsecure TCP/IP environments. It sets up
two sessions.
1The first one runs on TCP port 1723. It is used to start and manage the second one.
2The second one uses Generic Routing Encapsulation (GRE, RFC 2890) to transfer information
between the computers.
PPTP is convenient and easy-to-use, but you have to make sure that security policies support both
PPTP sessions.

CHAPTER 11
Trunks
11.1 Overview
Use trunks for WAN traffic load balancing to increase overall network throughput and reliability.
Load balancing divides traffic loads between multiple interfaces. This allows you to improve quality
of service and maximize bandwidth utilization for multiple ISP links.
Maybe you have two Internet connections with different bandwidths. You could set up a trunk that
uses spillover or weighted round robin load balancing so time-sensitive traffic (like video) usually
goes through the higher-bandwidth interface. For other traffic, you might want to use least load
first load balancing to even out the distribution of the traffic load.
Suppose ISP A has better connections to Europe while ISP B has better connections to Australia.
You could use policy routes and trunks to have traffic for your European branch office primarily use
ISP A and traffic for your Australian branch office primarily use ISP B.
Or maybe one of the UAG's interfaces is connected to an ISP that is also your Voice over IP (VoIP)
service provider. You can use policy routing to send the VoIP traffic through a trunk with the
interface connected to the VoIP service provider set to active and another interface (connected to
another ISP) set to passive. This way VoIP traffic goes through the interface connected to the VoIP
service provider whenever the interface’s connection is up.
11.1.1 What You Can Do in this Chapter
•Use the Trunk summary screen (Section 11.2 on page 198) to configure link sticking and view
the list of configured trunks and which load balancing algorithm each trunk uses.
•Use the Add Trunk screen (Section 11.2.1 on page 199) to configure the member interfaces for
a trunk and the load balancing algorithm the trunk uses.
•Use the Add System Default screen (Section 11.2.2 on page 201) to configure the load
balancing algorithm for the system default trunk.
11.1.2 What Yo u Need to Know
• Add WAN interfaces to trunks to have multiple connections share the traffic load.
• If one WAN interface’s connection goes down, the UAG sends traffic through another member of
the trunk.
• For example, you connect one WAN interface to one ISP and connect a second WAN interface to
a second ISP. The UAG balances the WAN traffic load between the connections. If one interface's
connection goes down, the UAG can automatically send its traffic through another interface.
You can also use trunks with policy routing to send specific traffic types through the best WAN
interface for that type of traffic.
Chapter 11 Trunks
UAG Series User’s Guide
196
• If that interface’s connection goes down, the UAG can still send its traffic through another
interface.
• You can define multiple trunks for the same physical interfaces.
Load Balancing Algorithms
The following sections describe the load balancing algorithms the UAG can use to decide which
interface the traffic (from the LAN) should use for a session2. The available bandwidth you
configure on the UAG refers to the actual bandwidth provided by the ISP and the measured
bandwidth refers to the bandwidth an interface is currently using.
Least Load First
The least load first algorithm uses the current (or recent) outbound bandwidth utilization of each
trunk member interface as the load balancing index(es) when making decisions about to which
interface a new session is to be distributed. The outbound bandwidth utilization is defined as the
measured outbound throughput over the available outbound bandwidth.
Here the UAG has two WAN interfaces connected to the Internet. The configured available outbound
bandwidths for wan1 and ppp0 are 512K and 256K respectively.
Figure 127 Least Load First Example
The outbound bandwidth utilization is used as the load balancing index. In this example, the
measured (current) outbound throughput of wan1 is 412K and ppp0 is 198K. The UAG calculates
the load balancing index as shown in the table below.
Since ppp0 has a smaller load balancing index (meaning that it is less utilized than wan1), the UAG
will send the subsequent new session traffic through ppp0.
Weighted Round Robin
Round Robin scheduling services queues on a rotating basis and is activated only when an interface
has more traffic than it can handle. A queue is given an amount of bandwidth irrespective of the
incoming traffic on that interface. This queue then moves to the back of the list. The next queue is
2. In the load balancing section, a session may refer to normal connection-oriented, UDP or SNMP2 traffic.
Ta ble 84 Least Load First Example

wan1 512 K 412 K 0.8
ppp0 256 K 198 K 0.77
Chapter 11 Trunks
UAG Series User’s Guide
197
given an equal amount of bandwidth, and then moves to the end of the list; and so on, depending
on the number of queues being used. This works in a looping fashion until a queue is empty.
The Weighted Round Robin (WRR) algorithm is best suited for situations when the bandwidths set
for the two WAN interfaces are different. Similar to the Round Robin (RR) algorithm, the Weighted
Round Robin (WRR) algorithm sets the UAG to send traffic through each WAN interface in turn. In
addition, the WAN interfaces are assigned weights. An interface with a larger weight gets more
chances to transmit traffic than an interface with a smaller weight.
For example, in the figure below, the configured available bandwidth of wan1 is 1M and ppp0 is
512K. You can set the UAG to distribute the network traffic between the two interfaces by setting
the weight of wan1 and ppp0 to 2 and 1 respectively. The UAG assigns the traffic of two sessions to
wan1 and one session's traffic to ppp0 in each round of 3 new sessions.
Figure 128 Weighted Round Robin Algorithm Example
Spillover
The spillover load balancing algorithm sends network traffic to the first interface in the trunk
member list until the interface’s maximum allowable load is reached, then sends the excess
network traffic of new sessions to the next interface in the trunk member list. This continues as
long as there are more member interfaces and traffic to be sent through them.
Suppose the first trunk member interface uses an unlimited access Internet connection and the
second is billed by usage. Spillover load balancing only uses the second interface when the traffic
load exceeds the threshold on the first interface. This fully utilizes the bandwidth of the first
interface to reduce Internet usage fees and avoid overloading the interface.
In this example figure, the upper threshold of the first interface is set to 800K. The UAG sends
network traffic of new sessions that exceed this limit to the secondary WAN interface.

CHAPTER 12
Policy and Static Routes
12.1 Policy and Static Routes Overview
Use policy routes and static routes to override the UAG’s default routing behavior in order to send
packets through the appropriate interface.
For example, the next figure shows a computer (A) connected to the UAG’s LAN interface. The UAG
routes most traffic from A to the Internet through the UAG’s default gateway (R1). You create one
policy route to connect to services offered by your ISP behind router R2. You create another policy
route to communicate with a separate network behind another router (R3) connected to the LAN.
Figure 133 Example of Policy Routing Topology
12.1.1 What You Can Do in this Chapter
•Use the Policy Route screens (see Section 12.2 on page 205) to list and configure policy routes.
•Use the Static Route screens (see Section 12.3 on page 211) to list and configure static routes.
12.1.2 What You Need to Know
Policy Routing
Traditionally, routing is based on the destination address only and the UAG takes the shortest path
to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing
behavior and alter the packet forwarding based on the policy defined by the network administrator.

LAN
Chapter 12 Policy and Static Routes
UAG Series User’s Guide
204
Policy-based routing is applied to incoming packets on a per interface basis, prior to the normal
routing.
How You Can Use Policy Routing
• Source-Based Routing – Network administrators can use policy-based routing to direct traffic
from different users through different connections.
• Cost Savings – IPPR allows organizations to distribute interactive traffic on high-bandwidth, high-
cost paths while using low-cost paths for batch traffic.
• Load Sharing – Network administrators can use IPPR to distribute traffic among multiple paths.
• NAT - The UAG performs NAT by default for traffic going to or from the WAN interfaces. A routing
policy’s SNAT allows network administrators to have traffic received on a specified interface use a
specified IP address as the source IP address.
Note: The UAG automatically uses SNAT for traffic it routes from internal interfaces to
external interfaces. For example LAN to WAN traffic.
Static Routes
The UAG usually uses the default gateway to route outbound traffic from computers on the LAN to
the Internet. To have the UAG send data to devices not reachable through the default gateway, use
static routes.
Policy Routes Versus Static Routes
• Policy routes are more flexible than static routes. You can select more criteria for the traffic to
match and can also use schedules, and NAT.
• Policy routes are only used within the UAG itself.
• Policy routes take priority over static routes. If you need to use a routing policy on the UAG and
propagate it to other routers, you could configure a policy route and an equivalent static route.
DiffServ
QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given
the same priority. CoS (class of service) is a way of managing traffic in a network by grouping
similar types of traffic together and treating each type as a class. You can use CoS to give different
priorities to different packet types.
DiffServ (Differentiated Services) is a class of service (CoS) model that marks packets so that they
receive specific per-hop treatment at DiffServ-compliant network devices along the route based on
the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs)
indicating the level of service desired. This allows the intermediary DiffServ-compliant network
devices to handle the packets differently depending on the code points without the need to
negotiate paths or remember state information for every flow. In addition, applications do not have
to request a particular service or give advanced notice of where the traffic is going.
Chapter 12 Policy and Static Routes
UAG Series User’s Guide
205
DSCP Marking and Per-Hop Behavior
DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service (TOS) field
in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define
up to 64 service levels. The following figure illustrates the DS field.
DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ
compliant, ToS-enabled network device will not conflict with the DSCP mapping.
The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet
gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be
marked for different kinds of forwarding. Resources can then be allocated according to the DSCP
values and the configured policies.

•See Section 12.4 on page 212 for more background information on policy routing.
12.2 Policy Route Screen
Click Configuration > Network > Routing to open the Policy Route screen. Use this screen to
see the configured policy routes.
A policy route defines the matching criteria and the action to take when a packet meets the criteria.
The action is taken only when all the criteria are met. The criteria can include the user name,
source address and incoming interface, destination address, schedule, IP protocol (ICMP, UDP, TCP,
etc.) and port.
The actions that can be taken include:
• Routing the packet to a different gateway, outgoing interface, or trunk.
IPPR follows the existing packet filtering facility of RAS in style and in implementation.

NAT and SNAT
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address in a packet
in one network to a different IP address in another network. Use SNAT (Source NAT) to change the
source IP address in one network to a different IP address in another network.
Assured Forwarding (AF) PHB for DiffServ
Assured Forwarding (AF) behavior is defined in RFC 2597. The AF behavior group defines four AF
classes. Inside each class, packets are given a high, medium or low drop precedence. The drop

Destination IP This parameter specifies the IP network address of the final destination. Routing is always
based on network number.
If you need to specify a route to a single host, enter the specific IP address here and use a
subnet mask of 255.255.255.255 (for IPv4) in the Subnet Mask field to force the network
number to be identical to the host ID.
Subnet Mask Enter the IP subnet mask here.
Gateway IP Select the radio button and enter the IP address of the next-hop gateway. The gateway is a
router or switch on the same segment as your UAG's interface(s). The gateway helps
forward packets to their destinations.
Interface Select the radio button and a predefined interface through which the traffic is sent.
Metric Metric represents the “cost” of transmission for routing purposes. IP routing uses hop count
as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a
number that approximates the cost for this link. The number need not be precise, but it
must be 0~127. In practice, 2 or 3 is usually a good number.

precedence determines the probability that routers in the network will drop packets when
congestion occurs. If congestion occurs between classes, the traffic in the higher class (smaller
numbered class) is generally given priority. Combining the classes and drop precedence produces

DDNS
13.1 DDNS Overview
Dynamic DNS (DDNS) services let you use a domain name with a dynamic IP address.
13.1.1 What You Can Do in this Chapter
•Use the DDNS screen (see Section 13.2 on page 215) to view a list of the configured DDNS
domain names and their details.
•Use the DDNS Add/Edit screen (see Section 13.2.1 on page 216) to add a domain name to the
UAG or to edit the configuration of an existing domain name.
13.1.2 What You Need to Know
DNS maps a domain name to a corresponding IP address and vice versa. Similarly, dynamic DNS
maps a domain name to a dynamic IP address. As a result, anyone can use the domain name to
contact you (in NetMeeting, CU-SeeMe, etc.) or to access your FTP server or Web site, regardless of
the current IP address.
Note: You must have a public WAN IP address to use Dynamic DNS.
You must set up a dynamic DNS account with a supported DNS service provider before you can use
Dynamic DNS services with the UAG. When registration is complete, the DNS service provider gives
you a password or key. At the time of writing, the UAG supports the following DNS service
providers. See the listed websites for details about the DNS services offered by each.
Note: Record your DDNS account’s user name, password, and domain name to use to
configure the UAG.
After, you configure the UAG, it automatically sends updated IP addresses to the DDNS service
provider, which helps redirect traffic accordingly.

NAT
14.1 NAT Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in
a packet. For example, the source address of an outgoing packet, used within one network is
changed to a different IP address known within another network. Use Network Address Translation
(NAT) to make computers on a private network behind the UAG available outside the private
network. If the UAG has only one public IP address, you can make the computers in the private
network available by using ports to forward packets to the appropriate private IP address.
Suppose you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example),
port 80 to another (B in the example) and assign a default server IP address of 172.16.0.35 to a
third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address.
The NAT network appears as a single host on the Internet.

Enable NAT
Loopback
Enable NAT loopback to allow users connected to any interface (instead of just the
specified Incoming Interface) to use the NAT rule’s specified Original IP address to
access the Mapped IP device. For users connected to the same interface as the Mapped
IP device, the UAG uses that interface’s IP address as the source address for the traffic it
sends from the users to the Mapped IP device.
For example, if you configure a NAT rule to forward traffic from the WAN to a LAN server,
enabling NAT loopback allows users connected to other interfaces to also access the
server. For LAN users, the UAG uses the LAN interface’s IP address as the source address
for the traffic it sends to the LAN server. See NAT Loopback on page 224 for more details.
If you do not enable NAT loopback, this NAT rule only applies to packets received on the
rule’s specified incoming interface.
Security Policy By default the Security Policy blocks incoming connections from external addresses. After
you configure your NAT rule settings, click the Securi ty Policy link to configure a
security policy to allow the NAT rule’s traffic to come in.
The UAG checks NAT rules before it applies To-Device security policies, so To-Device
security policies do not apply to traffic that is forwarded by NAT rules. The UAG still
checks other security policies according to the source IP address and mapped IP address.

14.3 NAT Technical Reference
Here is more detailed information about NAT on the UAG.
NAT Loopback
Suppose an NAT 1:1 rule maps a public IP address to the private IP address of a LAN SMTP e-mail
server to give WAN users access. NAT loopback allows other users to also use the rule’s original IP
to access the mail server.
For example, a LAN user’s computer at IP address 172.16.0.89 queries a public DNS server to
resolve the SMTP server’s domain name (xxx.LAN-SMTP.com in this example) and gets the SMTP
server’s mapped public IP address of 1.1.1.1.
Figure 143 LAN Computer Queries a Public DNS Server
The LAN user’s computer then sends traffic to IP address 1.1.1.1. NAT loopback uses the IP address
of the UAG’s lan1 interface (172.16.0.1) as the source address of the traffic going from the LAN
users to the LAN SMTP server.

Figure 144 LAN to LAN Traffic
The LAN SMTP server replies to the UAG’s LAN IP address and the UAG changes the source address
to 1.1.1.1 before sending it to the LAN user. The return traffic’s source matches the original
destination address (1.1.1.1). If the SMTP server replied directly to the LAN user without the traffic
going through NAT, the source would not match the original destination address which would cause
the LAN user’s computer to shut down the session.

VPN 1-1 Mapping
15.1 VPN 1-1 Mapping Overview
VPN 1-1 mapping allows an authenticated user in your network to access the Internet or an
external server using a public IP address different from the one used by the UAG’s WAN interface.
With VPN 1-1 mapping, each user that logs into the UAG and matches a pre-configured mapping
rule can obtain an individual public IP address.
For example, users A and B are behind the UAG and both want to use a unique WAN IP address to
access a public server through the UAG’s WAN1 interface. After the user is authenticated by the

CHAPTER 16
HTTP Redirect
16.1 Overview
HTTP redirect forwards the client’s HTTP request (except HTTP traffic destined for the UAG) to a web
proxy server. In the following example, proxy server A is connected to the lan2 interface in the
LAN2 zone. When a client connected to the lan1 interface in the LAN1 zone wants to open a web
page, its HTTP request is redirected to proxy server A first. If proxy server A cannot find the web
page in its cache, a policy route allows it to access the Internet to get them from a server. Proxy
server A then forwards the response to the client.
Figure 150 HTTP Redirect Example
16.1.1 What You Can Do in this Chapter
Use the HTTP Redirect screens (see Section 16.2 on page 232) to display and edit the HTTP
redirect rules.
16.1.2 What You Need to Know
Web Proxy Server
A proxy server helps client devices make indirect requests to access the Internet or outside network
resources/services. A proxy server can act as a firewall or an ALG (application layer gateway)
between the private network and the Internet or other networks. It also keeps hackers from
knowing internal IP addresses.
Chapter 16 HTTP Redirect
UAG Series User’s Guide
232
A client connects to a web proxy server each time he/she wants to access the Internet. The web
proxy provides caching service to allow quick access and reduce network usage. The proxy checks
its local cache for the requested web resource first. If it is not found, the proxy gets it from the
specified server and forwards the response to the client.
HTTP Redirect, Security Policy and Policy Route
With HTTP redirect, the relevant packet flow for HTTP traffic is:
1Security Policy
2HTTP Redirect
3Policy Route
Even if you set a policy route to the same incoming interface and service as a HTTP redirect rule,
the UAG checks the HTTP redirect rules first and forwards HTTP traffic to a proxy server if matched.
You need to make sure there is no security policy(ies) blocking the HTTP requests from the client to
the proxy server.
You also need to manually configure a policy route to forward the HTTP traffic from the proxy server
to the Internet. To make the example in Figure 150 on page 231 work, make sure you have the
following settings.
For HTTP traffic between lan1 and lan2:
• a from LAN1 to LAN2 security policy to allow HTTP requests from lan1 to lan2. Responses to this
request are allowed automatically.
• a HTTP redirect rule to forward HTTP traffic from lan1 to proxy server A.
For HTTP traffic between lan2 and wan1:
• a from LAN2 to WAN security policy (default) to allow HTTP requests from lan2 to wan1.
Responses to these requests are allowed automatically.
• a policy route to forward HTTP traffic from proxy server A to the Internet.

CHAPTER 17
SMTP Redirect
17.1 Overview
SMTP redirect forwards the authenticated client’s SMTP message to a SMTP server, that handles all
outgoing e-mail messages. In the following example, SMTP server A is connected to the lan2
interface in the LAN2 zone. When a client connected to the lan1 interface in the LAN1 zone logs
into the UAG and wants to send an e-mail, its SMTP message is redirected to SMTP server A. SMTP
server A then sends it to a mail server, where the message will be delivered to the recipient.
The UAG forwards SMTP traffic using TCP port 25.
Figure 153 SMTP Redirect Example
17.1.1 What You Can Do in this Chapter
Use the SMTP Redirect screens (see Section 17.2 on page 236) to display and edit the SMTP
redirect rules.
17.1.2 What You Need to Know
SMTP
Simple Mail Transfer Protocol (SMTP) is the Internet’s message transport standard. It controls the
sending of e-mail messages between servers. E-mail clients (also called e-mail applications) then
use mail server protocols such as POP (Post Office Protocol) or IMAP (Internet Message Access
Protocol) to retrieve e-mail. E-mail clients also generally use SMTP to send messages to a mail
Chapter 17 SMTP Redirect
UAG Series User’s Guide
236
server. The older POP2 requires SMTP for sending messages while the newer POP3 can be used with
or without it. This is why many e-mail applications require you to specify both the SMTP server and
the POP or IMAP server (even though they may actually be the same server).
SMTP Redirect, Security Policy and Policy Route
With SMTP redirect, the relevant packet flow for SMTP traffic is:
1Security Policy
2SMTP Redirect
3Policy Route
Even if you set a policy route to the same incoming interface and service as a SMTP redirect rule,
the UAG checks the SMTP redirect rules first and forwards SMTP traffic to a SMTP server if matched.
You need to make sure there is no security policy(ies) blocking the SMTP traffic from the client to
the SMTP server.
You also need to manually configure a policy route to forward the SMTP traffic from the SMTP server
to the Internet. To make the example in Figure 153 on page 235 work, make sure you have the
following settings.
For SMTP traffic between lan1 and lan2:
• a from LAN1 to LAN2 security policy to allow SMTP messages from lan1 to lan2. Responses to
this request are allowed automatically.
• a SMTP redirect rule to forward SMTP traffic from lan1 to SMTP server A.

CHAPTER 18
ALG
18.1 ALG Overview
Application Layer Gateway (ALG) allows the following application to operate properly through the
UAG’s NAT.
• FTP - File Transfer Protocol - an Internet file transfer service.
The ALG feature is only needed for traffic that goes through the UAG’s NAT.
18.1.1 What You Can Do in this Chapter
Use the ALG screen (Section 18.2 on page 240) to set up the FTP ALG settings.
18.1.2 What You Need to Know
Application Layer Gateway (ALG), NAT and Security Policy
The UAG can function as an Application Layer Gateway (ALG) to allow certain NAT un-friendly
applications to operate properly through the UAG’s NAT and security policies. The UAG dynamically
creates an implicit NAT session and security policy session for the application’s traffic from the WAN
to the LAN. The ALG on the UAG supports all of the UAG’s NAT mapping types.
FTP ALG
The FTP ALG allows TCP packets with a specified port destination to pass through. If the FTP server
is located on the LAN, you must also configure NAT (port forwarding) and security policies if you
want to allow access to the server from the WAN.
ALG and Trunks
If you send your ALG-managed traffic through an interface trunk and all of the interfaces are set to
active, you can configure routing policies to specify which interface the ALG-managed traffic uses.
You could also have a trunk with one interface set to active and a second interface set to passive.
The UAG does not automatically change ALG-managed connections to the second (passive)
interface when the active interface’s connection goes down. When the active interface’s connection
fails, the client needs to re-initialize the connection through the second interface (that was set to
passive) in order to have the connection go through the second interface.

CHAPTER 19
UPnP
19.1 Overview
The UAG supports both UPnP and NAT-PMP to permit networking devices to discover each other and
connect seamlessly.
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use. A
gateway that supports UPnP is called Internet Gateway Device (IGD). The standardized Device
Control Protocol (DCP) is defined by the UPnP Forum for IGDs to configure port mapping
automatically.
NAT Port Mapping Protocol (NAT-PMP), introduced by Apple and implemented in current Apple
products, is used as an alternative NAT traversal solution to the UPnP IGD protocol. NAT-PMP runs
over UDP port 5351. NAT-PMP is much simpler than UPnP IGD and mainly designed for small home
networks. It allows a client behind a NAT router to retrieve the router’s public IP address and port
number and make them known to the peer device with which it wants to communicate. The client
can automatically configure the NAT router to create a port mapping to allow the peer to contact it.
19.2 What You Need to Know
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP
compatible device installed on your network will appear as a separate icon. Selecting the icon of a
UPnP device will allow you to access the information and properties of that device.
19.2.1 NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP
network devices can automatically configure network addressing, announce their presence in the
network to other UPnP devices and enable exchange of simple product and service descriptions.
NAT traversal allows the following:
• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the NAT chapter for more information on NAT.
Chapter 19 UPnP
UAG Series User’s Guide
242
19.2.2 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
security policy ports may present network security issues. Network information and configuration
may also be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the UAG allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.

CHAPTER 20
IP/MAC Binding
20.1 IP/MAC Binding Overview
IP address to MAC address binding helps ensure that only the intended devices get to use privileged
IP addresses. The UAG uses DHCP to assign IP addresses and records to MAC address it assigned
each IP address. The UAG then checks incoming connection attempts against this list. A user
cannot manually assign another IP to his computer and use it to connect to the UAG.
Suppose you configure access privileges for IP address 172.16.1.27 and use static DHCP to assign
it to Bob’s computer’s MAC address of 12:34:56:78:90:AB. IP/MAC binding drops traffic from any
computer trying to use IP address 172.16.1.27 with another MAC address.
Figure 167 IP/MAC Binding Example
20.1.1 What You Can Do in this Chapter
•Use the Summary and Edit screens (Section 20.2 on page 249) to bind IP addresses to MAC
addresses.
•Use the Exempt List screen (Section 20.3 on page 251) to configure ranges of IP addresses to
which the UAG does not apply IP/MAC binding.

Layer 2 Isolation
21.1 Overview
Layer-2 isolation is used to prevent connected devices from communicating with each other in the
UAG’s local network(s), except for the devices in the white list, when layer-2 isolation is enabled on
the UAG and the local interface(s).
Note: The security policy control must be enabled before you can use layer-2 isolation.
In the following example, layer-2 isolation is enabled on the UAG’s interface Vlan1. A printer, PC
and AP are in the Vlan1. The IP address of network printer (C) is added to the white list. With this
setting, the connected AP then cannot communicate with the PC (D), but can access the network
printer (C), server (B), wireless client (A) and the Internet.

CHAPTER 22
IPnP
22.1 Overview
IP Plug and Play (IPnP) allows a computer to access the Internet without changing the network
settings (such as IP address and subnet mask) of the computer, even when the IP addresses of the
computer and the UAG are not in the same subnet.
When you disable the IPnP feature, only computers with dynamic IP addresses or static IP
addresses in the same subnet as the UAG’s LAN IP address can connect to the UAG or access the
Internet through the UAG.
The IPnP feature does not apply to a computer using either a dynamic IP address or a static IP
address that is in the same subnet as the UAG's IP address.
Note: You must enable NAT to use the IPnP feature.
The following figure depicts a scenario where a computer is set to use a static private IP address in
the corporate environment. In a residential house where a UAG is installed, you can still use the
computer to access the Internet without changing the network settings, even when the IP
addresses of the computer and the UAG are not in the same subnet.

CHAPTER 23
Web Authentication
23.1 Overview
Web authentication can intercepts network traffic, according to the authentication policies, until the
user authenticates his or her connection, usually through a specifically designated login web page
or user agreement page. This means all web page requests can initially be redirected to a special
web page that requires users to authenticate their sessions. Once authentication is successful, they
can then connect to the rest of the network or Internet.
As soon as a user attempt to open a web page, the UAG reroutes his/her browser to a web portal
page that prompts he/she to log in or agree to the policy of user agreement.
Figure 178 Web Authentication Example
The web authentication page only appears once per authentication session. Unless a user session
times out or he/she closes the connection, he or she generally will not see it again during the same
session.
23.1.1 What You Can Do in this Chapter
•Use the Configuration > Web Authentication screens (Section 23.2 on page 260) to enable
web authentication, set the logout IP, create and manage web authentication policies, configure
authentication type profiles and upload or download custom files.
•Use the Configuration > Web Authentication > Walled Garden screens (Section 23.3 on
page 277) to enable and create walled garden links that display in the login screen.
Chapter 23 Web Authentication
UAG Series User’s Guide

•Use the Configuration > Web Authentication > Advertisement screens (Section 23.4 on
page 283) to enable and set advertisement links.
23.1.2 What You Need to Know
Forced User Authentication
Instead of making users for which user-aware policies have been configured go to the UAG Login
screen manually, you can configure the UAG to display the Login screen automatically whenever it
routes HTTP traffic for anyone who has not logged in yet.
Note: This works with HTTP traffic only. The UAG does not display the Login screen when
users attempt to send other kinds of traffic.
The UAG does not automatically route the request that prompted the login, however, so users have
to make this request again.

See Section 23.2.2 on page 264 for an example of using an authentication policy for user-aware
access control.

configuring the RADIUS server’s address, authentication port, and key; set the Group
Membership Attribute field to the attribute that the UAG is to check to determine to which group
a user belongs. This example uses Class. This attribute’s value is called a group identifier; it
determines to which group a user belongs. In this example the values are Finance, Engineer, Sales,
and Boss.

RTLS
24.1 Overview
Ekahau RTLS (Real Time Location Service) tracks battery-powered Wi-Fi tags attached to APs
managed by the UAG to create maps, alerts, and reports.
The Ekahau RTLS Controller is the centerpiece of the RTLS system. This server software runs on a
Windows computer to track and locate Ekahau tags from Wi-Fi signal strength measurements. Use
the UAG with the Ekahau RTLS system to take signal strength measurements at the APs (Integrated
Approach / Blink Mode).
The following example shows the Ekahau RTLS Integrated Approach (Blink Mode).
1The Wi-Fi tag sends blink packets at specified intervals (or triggered by something like motion or
button presses).
2The APs pick up the blink packets, measure the signal strength, and send it to the UAG.
3The UAG forwards the signal measurements to the Ekahau RTLS Controller.
4The Ekahau RTLS Controller calculates the tag positions.
Figure 203 RTLS Example
24.1.1 What You Can Do in this Chapter
Use the RTLS screen (Section 24.3 on page 287) to use the managed APs as part of an Ekahau
RTLS to track the location of Ekahau Wi-Fi tags.
Chapter 24 RTLS
UAG Series User’s Guide
287
24.2 Before You Begin
You need:
• At least three APs managed by the UAG (the more APs the better since it increases the amount of
information the Ekahau RTLS Controller has for calculating the location of the tags)
• IP addresses for the Ekahau Wi-Fi tags
• A dedicated RTLS SSID is recommended
• Ekahau RTLS Controller in blink mode with TZSP Updater enabled
• Security policies to allow RTLS traffic if the UAG security policy control is enabled or the Ekahau
RTLS Controller is behind a firewall.
For example, if the Ekahau RTLS Controller is behind a firewall, open ports 8550, 8553, and 8569 to
allow traffic the APs send to reach the Ekahau RTLS Controller.
The following table lists default port numbers and types of packets RTLS uses.

CHAPTER 25
Security Policy
25.1 Overview
A security policy is a template of security settings that can be applied to specific traffic at specific
times. The policy can be applied:
• to a specific direction of travel of packets (from / to)
• to a specific source and destination address objects
• to a specific type of traffic (services)
• to a specific user or group of users
• at a specific schedule
The policy can be configured:
• to allow or deny traffic that matches the criteria above
• send a log or alert for traffic that matches the criteria above
• to apply the actions configured in the UTM profiles (application patrol, content filter) to traffic
that matches the criteria above
The security policies can also limit the number of user sessions.
The following example shows the UAG’s default security policy behavior for WAN to LAN traffic and
how stateful inspection works. A LAN user can initiate a Telnet session from within the LAN zone
and the UAG allows the response. However, the UAG blocks Telnet traffic initiated from the WAN
zone and destined for the LAN zone.
Figure 205 Default Security Policy Action
25.1.1 What You Can Do in this Chapter
•Use the Security Policy Control screens (Section 25.2 on page 291) to enable or disable policy
control and asymmetrical routes, and manage and configure policies.
•Use the Session Control screens (see Section 25.3 on page 296) to limit the number of
concurrent NAT/security policies sessions a client can use.
Chapter 25 Security Policy
UAG Series User’s Guide
290
25.1.2 What You Need to Know
Stateful Inspection
The UAG uses stateful inspection in its security policies. The UAG restricts access by screening data
packets against defined access rules. It also inspects sessions. For example, traffic from one zone is
not allowed unless it is initiated by a computer in another zone first.
Zones
A zone is a group of interfaces. Group the UAG’s interfaces into different zones based on your
needs. You can configure security policies for data passing between zones or even between
interfaces.
Default Security Policy Behavior
Security policies are grouped based on the direction of travel of packets to which they apply. Here is
the default security policy behavior for traffic going through the UAG in various directions.
Note: Intra-zone traffic (such as LAN to LAN traffic or WAN to WAN traffic) can also be
blocked by the zone configuration. See Section 34.2.1 on page 397 for details.
To-Device Rules
Rules with Device as the To Zone apply to traffic going to the UAG itself. By default:
• The security policy allows only LAN, or WAN computers to access or manage the UAG.
• The UAG allows DHCP traffic from any interface to the UAG.
• The UAG drops most packets from the WAN zone to the UAG itself and generates a log except for
AH, ESP, GRE, HTTPS, IKE, NATT.
When you configure a security policy for packets destined for the UAG itself, make sure it does not
conflict with your service control rule. See Chapter 46 on page 486 for more information about
Table 129 Default Security Policy Behavior
FROM ZONE TO ZONE BEHAVIOR
From any to Device DHCP traffic from any interface to the UAG is allowed.
From LAN1 to any (other than
the UAG)
Traffic from the LAN1 to any of the networks connected to the UAG is allowed.
From LAN2 to any (other than
the UAG)
Traffic from the LAN2 to any of the networks connected to the UAG is allowed.
From LAN1 to Device Traffic from the LAN1 to the UAG itself is allowed.
From LAN2 to Device Traffic from the LAN2 to the UAG itself is allowed.
From WAN to Device The default services listed in To-Device Rules on page 290 are allowed from
the WAN to the UAG itself. All other WAN to UAG traffic is dropped.
From any to any Traffic that does not match any security policy is dropped. This includes traffic
from the WAN to any of the networks behind the UAG.
This also includes traffic to or from interfaces that are not assigned to a zone
(extra-zone traffic).
Chapter 25 Security Policy
UAG Series User’s Guide
291
service control (remote management). The UAG checks the security policies before the service
control rules for traffic destined for the UAG.
A From Any To Device direction rule applies to traffic from an interface which is not in a zone.
Global Security Policies
Security policies with from any and/or to any as the packet direction are called global security
policies. The global security policies are the only security policies that apply to an interface that is
not included in a zone. The from any rules apply to traffic coming from the interface and the to
any rules apply to traffic going to the interface.
Security Policy Rule Criteria
The UAG checks the schedule, user name (user’s login name on the UAG), source IP address,
destination IP address and IP protocol type of network traffic against the policy control rules (in the
order you list them). When the traffic matches a rule, the UAG takes the action specified in the rule.
User Specific Security Policies
You can specify users or user groups in security policies. For example, to allow a specific user from
any computer to access a zone by logging in to the UAG, you can set up a policy based on the user
name only. If you also apply a schedule to the security policy, the user can only access the network
at the scheduled time. A user-aware security policy is activated whenever the user logs in to the
UAG and will be disabled after the user logs out of the UAG.
Session Limits
Accessing the UAG or network resources through the UAG requires a NAT session and
corresponding security policy session. Peer to peer applications, such as file sharing applications,
may use a large number of NAT sessions. A single client could use all of the available NAT sessions
and prevent others from connecting to or through the UAG. The UAG lets you limit the number of
concurrent NAT/security policy sessions a client can use.
Finding Out More
•See Section 25.4 on page 299 for an example of creating security policies as part of configuring
user-aware access control.
25.2 Security Policy Control Screen
Asymmetrical Routes
If an alternate gateway on the LAN has an IP address in the same subnet as the UAG’s LAN IP
address, return traffic may not go through the UAG. This is called an asymmetrical or “triangle”
route. This causes the UAG to reset the connection, as the connection has not been acknowledged.
You can have the UAG permit the use of asymmetrical route topology on the network (not reset the
connection). However, allowing asymmetrical routes may let traffic from the WAN go directly to the
LAN without passing through the UAG. A better solution is to use virtual interfaces to put the UAG
Chapter 25 Security Policy
UAG Series User’s Guide
292
and the backup gateway on separate subnets. Virtual interfaces allow you to partition your network
into logical sections over the same interface. See the chapter about interfaces for more information.
By putting LAN 1 and the alternate gateway (A in the figure) in different subnets, all returning
network traffic must pass through the UAG to the LAN. The following steps and figure describe such
a scenario.
1A computer on the LAN1 initiates a connection by sending a SYN packet to a receiving server on the
WAN.
2The UAG reroutes the packet to gateway A, which is in Subnet 2.
3The reply from the WAN goes to the UAG.
4The UAG then sends it to the computer on the LAN1 in Subnet 1.
Figure 206 Using Virtual Interfaces to Avoid Asymmetrical Routes
25.2.1 Configuring the Security Policy Control Screen
Click Configuration > Security Policy > Policy Control to open the Policy screen. Use this
screen to enable or disable policy control and asymmetrical routes, set a maximum number of
sessions per host, and display the configured policy control rules. Specify from which zone packets
come and to which zone packets travel to display only the rules specific to the selected direction.
Note the following.
• Besides configuring policy control, you also need to configure NAT rules to allow computers on
the WAN to access LAN devices. See Chapter 14 on page 219 for more information.
• The UAG applies NAT (Destination NAT) settings before applying the policy control rules. So for
example, if you configure a NAT entry that sends WAN traffic to a LAN IP address, when you
configure a corresponding policy control rule to allow the traffic, you need to set the LAN IP
address as the destination.
• The ordering of your rules is very important as rules are applied in sequence.

25.5 Security Policy Example Applications
Suppose you decide to block LAN users from using IRC (Internet Relay Chat) through the Internet.
To do this, you would configure a LAN to WAN security policy that blocks IRC traffic from any source
IP address from going to any destination address. You do not need to specify a schedule since you
need the security policy to always be in effect. The following figure shows the results of this rule.
Figure 216 Blocking All LAN to WAN IRC Traffic Example
Your security policy would have the following settings.
• The first row blocks LAN access to the IRC service on the WAN.
• The second row is the security policy’s default policy that allows all LAN1 to WAN traffic.
The UAG applies the security policies in order. So for this example, when the UAG receives traffic
from the LAN, it checks it against the first rule. If the traffic matches (if it is IRC traffic) the security
policy takes the action in the rule (drop) and stops checking the subsequent security policies. Any
traffic that does not match the first security policy will match the second policy and the UAG
forwards it.
Table 134 Blocking All LAN to WAN IRC Traffic Example
#USER SOURCE DESTINATION SCHEDULE SERVICE ACTION
1 Any Any Any Any IRC Deny
2 Any Any Any Any Any Allow
Chapter 25 Security Policy
UAG Series User’s Guide

Now suppose you need to let the CEO use IRC. You configure a LAN1 to WAN security policy that
allows IRC traffic from the IP address of the CEO’s computer. You can also configure a LAN to WAN
policy that allows IRC traffic from any computer through which the CEO logs into the UAG with his/
her user name. In order to make sure that the CEO’s computer always uses the same IP address,
make sure it either:
• Has a static IP address,
or
• You configure a static DHCP entry for it so the UAG always assigns it the same IP address (see
DHCP Settings on page 192 for information on DHCP).
Now you configure a LAN1 to WAN security policy that allows IRC traffic from the IP address of the
CEO’s computer (172.16.1.7 for example) to go to any destination address. You do not need to
specify a schedule since you want the security policy to always be in effect. The following figure
shows the results of your two custom rules.
Figure 217 Limited LAN to WAN IRC Traffic Example
Your security policy would have the following configuration.
• The first row allows the LAN1 computer at IP address 172.16.1.7 to access the IRC service on the
WAN.
• The second row blocks LAN1 access to the IRC service on the WAN.
• The third row is the security policy’s default policy of allowing all traffic from the LAN1 to go to
the WAN.
Alternatively, you configure a LAN1 to WAN security policy with the CEO’s user name (say CEO) to
allow IRC traffic from any source IP address to go to any destination address.
Table 135 Limited LAN1 to WAN IRC Traffic Example 1
#USER SOURCE DESTINATION SCHEDULE SERVICE ACTION

2 Any Any Any Any IRC Deny

Your security policy would have the following configuration.
• The first row allows any LAN1 computer to access the IRC service on the WAN by logging into the
UAG with the CEO’s user name.
• The second row blocks LAN1 access to the IRC service on the WAN.
• The third row is the security policy’s default policy of allowing all traffic from the LAN1 to go to
the WAN.
The policy for the CEO must come before the policy that blocks all LAN1 to WAN IRC traffic. If the
policy that blocks all LAN1 to WAN IRC traffic came first, the CEO’s IRC traffic would match that
policy and the UAG would drop it and not check any other security policies.

CHAPTER 26
Billing
26.1 Overview
You can use the built-in billing function to setup billing profiles. A billing profile describes how to
charge users. This chapter also shows you how to select an accounting method, configure a
discount price plan or use an online payment service by credit card.
26.1.1 What You Can Do in this Chapter
•Use the General screen (see Section 26.2 on page 305) to configure the general billing settings,
such as the accounting method, currency unit and the SSID profiles to which the settings are
applied.
•Use the Billing Profile screen (see Section 26.3 on page 307) to configure the billing profiles for
the web-based account generator and each button on the connected statement printer.
•Use the Discount screen (see Section 26.4 on page 314) to enable and configure discount price
plans.
•Use the Payment Service screen (see Section 26.5 on page 316) to enable online payment
service and configure the service pages.
26.1.2 What You Need to Know
Accumulation Accounting Method
The accumulation accounting method allows multiple re-logins until the allocated time period or
until the user account is expired. The UAG accounts the time that the user is logged in for Internet
access.
Time-to-finish Accounting Method
The time-to-finish accounting method is good for one-time logins. Once a user logs in, the UAG
stores the IP address of the user’s computer for the duration of the time allocated. Thus the user
does not have to enter the user name and password again for re-login within the allocated time.
Once activated, the user account is valid until the allocated time is reached even if the user
disconnects Internet access for a certain period within the allocated time. For example, Joe
purchases a one-hour time-to-finish account. He starts using the Internet for the first 20 minutes
and then disconnects his Internet access to go to a 20-minute meeting. After the meeting, he only
has 20 minutes left on his account.

Method
Select Time to Finish to allow each user a one-time login. Once the user logs in, the
system starts counting down the pre-defined usage even if the user stops the Internet
access before the time period is finished. If a user disconnects and reconnects before the
allocated time expires, the user does not have to enter the user name and password to
access the Internet again.
Select Accumulation to allow each user multiple re-login until the time allocated is used
up. The UAG accounts the time that the user is logged in for Internet access.
User idle

27.4.6 Account Report Notes
The daily, monthly or last month account report holds up to 2000 entries. If there are more than
2000 accounts created in the same month or same day, the account report’s calculations only
include the latest 2000.
For example, if 2030 accounts (each priced at $1) have been created from 2013/05/01 00:00:00 to
2013/05/31 19:59:59, the monthly account report includes the latest 2000 accounts, so the total
would be $2,000 instead of $2,030.

CHAPTER 30
IPSec VPN
30.1 Virtual Private Networks (VPN) Overview
A virtual private network (VPN) provides secure communications between sites without the expense
of leased site-to-site lines. A secure VPN is a combination of tunneling, encryption, authentication,
access control and auditing. It is used to transport traffic over the Internet or any insecure network
that uses TCP/IP for communication.
IPSec VPN
Internet Protocol Security (IPSec) VPN connects IPSec routers or remote users using IPSec client
software. This standards-based VPN offers flexible solutions for secure data communications across
a public network. IPSec is built around a number of standardized cryptographic techniques to
provide confidentiality, data integrity and authentication at the IP layer. The UAG can also combine
multiple IPSec VPN connections into one secure network. Here local UAG X uses an IPSec VPN
tunnel to remote (peer) UAG Y to connect the local (A) and remote (B) networks.
Figure 239 IPSec VPN Example
30.1.1 What You Can Do in this Chapter
•Use the VPN Connection screens (see Section 30.2 on page 340) to specify which IPSec VPN
gateway an IPSec VPN connection policy uses, which devices behind the IPSec routers can use
the VPN tunnel, and the IPSec SA settings (phase 2 settings). You can also activate or deactivate
and connect or disconnect each VPN connection (each IPSec SA).
•Use the VPN Gateway screens (see Section 30.3 on page 347) to manage the UAG’s VPN
gateways. A VPN gateway specifies the IPSec routers at either end of a VPN tunnel and the IKE
SA settings (phase 1 settings). You can also activate and deactivate each VPN gateway.
Chapter 30 IPSec VPN
UAG Series User’s Guide
339
30.1.2 What You Need to Know
An IPSec VPN tunnel is usually established in two phases. Each phase establishes a security
association (SA), a contract indicating what security parameters the UAG and the remote IPSec
router will use. The first phase establishes an Internet Key Exchange (IKE) SA between the UAG
and remote IPSec router. The second phase uses the IKE SA to securely establish an IPSec SA
through which the UAG and remote IPSec router can send data between computers on the local
network and remote network. This is illustrated in the following figure.
Figure 240 VPN: IKE SA and IPSec SA
In this example, a computer in network A is exchanging data with a computer in network B. Inside
networks A and B, the data is transmitted the same way data is normally transmitted in the
networks. Between routers X and Y, the data is protected by tunneling, encryption, authentication,
and other security features of the IPSec SA. The IPSec SA is secure because routers X and Y
established the IKE SA first.
Finding Out More
•See Section 30.4 on page 354 for IPSec VPN background information.
• See the help in the IPSec VPN quick setup wizard screens.
30.1.3 Before You Begin
This section briefly explains the relationship between VPN tunnels and other features. It also gives
some basic suggestions for troubleshooting.
You should set up the following features before you set up the VPN tunnel.
• In any VPN connection, you have to select address objects to specify the local policy and remote
policy. You should set up the address objects first.
• In a VPN gateway, you can select an Ethernet interface, virtual Ethernet interface, VLAN
interface, or virtual VLAN interface to specify what address the UAG uses as its IP address when
it establishes the IKE SA. You should set up the interface first. See Chapter 10 on page 154.
• In a VPN gateway, you can enable extended authentication. If the UAG is in server mode, you
should set up the authentication method (AAA server) first. The authentication method specifies
how the UAG authenticates the remote IPSec router. See Chapter 42 on page 459.
Chapter 30 IPSec VPN
UAG Series User’s Guide
340
• In a VPN gateway, the UAG and remote IPSec router can use certificates to authenticate each
other. Make sure the UAG and the remote IPSec router will trust each other’s certificates. See
Chapter 44 on page 467.
30.2 The VPN Connection Screen

Active Protocol Select which protocol you want to use in the IPSec SA. Choices are:
AH (RFC 2402) - provides integrity, authentication, sequence integrity (replay
resistance), and non-repudiation but not encryption. If you select AH, you must
select an Authentication algorithm.
ESP (RFC 2406) - provides encryption and the same services offered by AH, but its
authentication is weaker. If you select ESP, you must select an Encryption algorithm
and Authentication algorithm.
Both AH and ESP increase processing requirements and latency (delay).
The UAG and remote IPSec router must use the same active protocol.
Encapsulation Select which type of encapsulation the IPSec SA uses. Choices are
Tunnel - this mode encrypts the IP header information and the data.
Transport - this mode only encrypts the data.

If you select Domain Name / IPv4, enter the domain name or the IP address of the
UAG. The IP address of the UAG in the IKE SA is the specified IP address or the IP
address corresponding to the domain name. 0.0.0.0 is not generally recommended as it
has the UAG accept IPSec requests destined for any interface address on the UAG.
Peer Gateway
Address Select how the IP address of the remote IPSec router in the IKE SA is defined.
Select Static Address to enter the domain name or the IP address of the remote IPSec
router. You can provide a second IP address or domain name for the UAG to try if it
cannot establish an IKE SA with the first one.
Fall back to Primary Peer Gateway when possible: When you select this, if the
connection to the primary address goes down and the UAG changes to using the
secondary connection, the UAG will reconnect to the primary address when it
becomes available again and stop using the secondary connection. Users will lose
their VPN connection briefly while the UAG changes back to the primary connection.
To use this, the peer device at the secondary address cannot be set to use a nailed-
up VPN connection. In the Fall Back Check Interval field, set how often to check if
the primary address is available.
Authentication Note: The UAG and remote IPSec router must use the same authentication method to
establish the IKE SA.
Pre-Shared Key Select this to have the UAG and remote IPSec router use a pre-shared key (password)
to identify each other when they negotiate the IKE SA. Type the pre-shared key in the
field to the right. The pre-shared key can be:
• alphanumeric characters or ,;.|`~!@#$%^&*()_+\{}':./<>=-"
• pairs of hexadecimal (0-9, A-F) characters, preceded by “0x”.
Type “0x” at the beginning of a hexadecimal key. For example,
"0x0123456789ABCDEF" is in hexadecimal format; “0123456789ABCDEF” is in ASCII
format. If you use hexadecimal, you must enter twice as many characters since you
need to enter pairs.
The UAG and remote IPSec router must use the same pre-shared key.

Certificate Select this to have the UAG and remote IPSec router use certificates to authenticate
each other when they negotiate the IKE SA. Then select the certificate the UAG uses to
identify itself to the remote IPSec router.
This certificate is one of the certificates in My Certificate s. If this certificate is self-
signed, import it into the remote IPsec router. If this certificate is signed by a CA, the
remote IPsec router must trust that CA.
Note: The IPSec routers must trust each other’s certificates.
The UAG uses one of its Trusted Certificates to authenticate the remote IPSec
router’s certificate. The trusted certificate can be a self-signed certificate or that of a
trusted CA that signed the remote IPSec router’s certificate.
User Based PSK User-based PSK (IKEv1 only) generates and manages separate pre-shared keys for
every user. This enables multiple users, each with a unique key, to access the same
VPN gateway policy with one-to-one authentication and strong encryption. Access can
be denied on a per-user basis thus allowing VPN SA user-based policies. Click User
Based PSK then select a user or group object who is allowed VPN SA access using this
VPN gateway policy. This is for IKEv1 only.

encrypt and decrypt information. Both routers must use the same DH key group.
NAT Traversal Select this if any of these conditions are satisfied.
• This IKE SA might be used to negotiate IPSec SAs that use ESP as the active
protocol.
• There are one or more NAT routers between the UAG and remote IPSec router, and
these routers do not support IPSec pass-thru or a similar feature.
The remote IPSec router must also enable NAT traversal, and the NAT routers have to
forward packets with UDP port 500 and UDP 4500 headers unchanged.

Detection (DPD) Select this check box if you want the UAG to make sure the remote IPSec router is
there before it transmits data through the IKE SA. The remote IPSec router must
support DPD. If there has been no traffic for at least 15 seconds, the UAG sends a
message to the remote IPSec router. If the remote IPSec router responds, the UAG
transmits the data. If the remote IPSec router does not respond, the UAG shuts down
the IKE SA.
If the remote IPSec router does not support DPD, see if you can use the VPN connection
connectivity check (see Section 30.2.1 on page 341).
X-Auth When multiple IPSec routers use the same VPN tunnel to connect to a single VPN tunnel
(telecommuters sharing a tunnel for example), use extended authentication to enforce
a user name and password check. This way even though they all know the VPN tunnel’s
security settings, each still has to provide a unique user name and password.

30.4 IPSec VPN Background Information
Here is some more detailed IPSec VPN background information.
IKE SA Overview
The IKE SA provides a secure connection between the UAG and remote IPSec router.
It takes several steps to establish an IKE SA. The negotiation mode determines how many. There
are two negotiation modes--main mode and aggressive mode. Main mode provides better security,
while aggressive mode is faster.
Note: Both routers must use the same negotiation mode.
These modes are discussed in more detail in Negotiation Mode on page 357. Main mode is used in
various examples in the rest of this section.
IP Addresses of the UAG and Remote IPSec Router
To set up an IKE SA, you have to specify the IP addresses of the UAG and remote IPSec router. You
can usually enter a static IP address or a domain name for either or both IP addresses. Sometimes,
your UAG might offer another alternative, such as using the IP address of a port or interface, as
well.
You can also specify the IP address of the remote IPSec router as 0.0.0.0. This means that the
remote IPSec router can have any IP address. In this case, only the remote IPSec router can initiate
an IKE SA because the UAG does not know the IP address of the remote IPSec router. This is often
used for telecommuters.
IKE SA Proposal
The IKE SA proposal is used to identify the encryption algorithm, authentication algorithm, and
Diffie-Hellman (DH) key group that the UAG and remote IPSec router use in the IKE SA. In main
mode, this is done in steps 1 and 2, as illustrated next.
User Name This field is required if the UAG is in Cl ient Mode for extended authentication. Type the
user name the UAG sends to the remote IPSec router. The user name can be 1-31
ASCII characters. It is case-sensitive, but spaces are not allowed.

Figure 245 IKE SA: Main Negotiation Mode, Steps 1 - 2: IKE SA Proposal
The UAG sends one or more proposals to the remote IPSec router. (In some devices, you can only
set up one proposal.) Each proposal consists of an encryption algorithm, authentication algorithm,
and DH key group that the UAG wants to use in the IKE SA. The remote IPSec router selects an
acceptable proposal and sends the accepted proposal back to the UAG. If the remote IPSec router
rejects all of the proposals, the UAG and remote IPSec router cannot establish an IKE SA.
Note: Both routers must use the same encryption algorithm, authentication algorithm,
and DH key group.
In most UAGs, you can select one of the following encryption algorithms for each proposal. The
algorithms are listed in order from weakest to strongest.
• Data Encryption Standard (DES) is a widely used method of data encryption. It applies a 56-bit
key to each 64-bit block of data.
• Triple DES (3DES) is a variant of DES. It iterates three times with three separate keys, effectively
tripling the strength of DES.
• Advanced Encryption Standard (AES) is a newer method of data encryption that also uses a
secret key. AES applies a 128-bit key to 128-bit blocks of data. It is faster than 3DES.
Some UAGs also offer stronger forms of AES that apply 192-bit or 256-bit keys to 128-bit blocks of
data.
In most UAGs, you can select one of the following authentication algorithms for each proposal. The
algorithms are listed in order from weakest to strongest.
• MD5 (Message Digest 5) produces a 128-bit digest to authenticate packet data.
• SHA1 (Secure Hash Algorithm) produces a 160-bit digest to authenticate packet data.
• SHA256 (Secure Hash Algorithm) produces a 256-bit digest to authenticate packet data.
• SHA512 (Secure Hash Algorithm) produces a 512-bit digest to authenticate packet data.
See Diffie-Hellman (DH) Key Exchange on page 355 for more information about DH key groups.
Diffie-Hellman (DH) Key Exchange
The UAG and the remote IPSec router use DH public-key cryptography to establish a shared secret.
The shared secret is then used to generate encryption keys for the IKE SA and IPSec SA. In main
mode, this is done in steps 3 and 4, as illustrated next.
One or more proposals, each one consisting of:

- authentication algorithm

Figure 246 IKE SA: Main Negotiation Mode, Steps 3 - 4: DH Key Exchange
DH public-key cryptography is based on DH key groups. Each key group is a fixed number of bits
long. The longer the key, the more secure the encryption, but also the longer it takes to encrypt
and decrypt information. For example, DH2 keys (1024 bits) are more secure than DH1 keys (768
bits), but DH2 keys take longer to encrypt and decrypt.
Authentication
Before the UAG and remote IPSec router establish an IKE SA, they have to verify each other’s
identity. This process is based on pre-shared keys and router identities.
In main mode, the UAG and remote IPSec router authenticate each other in steps 5 and 6, as
illustrated below. The identities are also encrypted using the encryption algorithm and encryption
key the UAG and remote IPSec router selected in previous steps.
Figure 247 IKE SA: Main Negotiation Mode, Steps 5 - 6: Authentication (continued)
You have to create (and distribute) a pre-shared key. The UAG and remote IPSec router use it in
the authentication process, though it is not actually transmitted or exchanged.
Note: The UAG and the remote IPSec router must use the same pre-shared key.
Router identity consists of ID type and content. The ID type can be domain name, IP address, or e-
mail address, and the content is a (properly-formatted) domain name, IP address, or e-mail
address. The content is only used for identification. Any domain name or e-mail address that you

enter does not have to actually exist. Similarly, any domain name or IP address that you enter does
not have to correspond to the UAG’s or remote IPSec router’s properties.
The UAG and the remote IPSec router have their own identities, so both of them must store two
sets of information, one for themselves and one for the other router. Local ID type and content
refers to the ID type and content that applies to the router itself, and peer ID type and content
refers to the ID type and content that applies to the other router.
Note: The UAG’s local and peer ID type and content must match the remote IPSec
router’s peer and local ID type and content, respectively.
For example, in Table 159 on page 357, the UAG and the remote IPSec router authenticate each
other successfully. In contrast, in Table 160 on page 357, the UAG and the remote IPSec router
cannot authenticate each other and, therefore, cannot establish an IKE SA.
It is also possible to configure the UAG to ignore the identity of the remote IPSec router. In this
case, you usually set the peer ID type to Any. This is less secure, so you should only use this if your
UAG provides another way to check the identity of the remote IPSec router (for example, extended
authentication) or if you are troubleshooting a VPN tunnel.
Additional Topics for IKE SA
This section provides more information about IKE SA.
Negotiation Mode
There are two negotiation modes--main mode and aggressive mode. Main mode provides better
security, while aggressive mode is faster.
Main mode takes six steps to establish an IKE SA.
Steps 1 - 2: The UAG sends its proposals to the remote IPSec router. The remote IPSec router
selects an acceptable proposal and sends it back to the UAG.
Steps 3 - 4: The UAG and the remote IPSec router exchange pre-shared keys for authentication
and participate in a Diffie-Hellman key exchange, based on the accepted DH key group, to establish
a shared secret.

358
Steps 5 - 6: Finally, the UAG and the remote IPSec router generate an encryption key (from the
shared secret), encrypt their identities, and exchange their encrypted identity information for
authentication.
In contrast, aggressive mode only takes three steps to establish an IKE SA. Aggressive mode does
not provide as much security because the identity of the UAG and the identity of the remote IPSec
router are not encrypted. It is usually used in remote-access situations, where the address of the
initiator is not known by the responder and both parties want to use pre-shared keys for
authentication. For example, the remote IPSec router may be a telecommuter who does not have a
static IP address.
VPN, NAT, and NAT Traversal
In the following example, there is another router (A) between router X and router Y.
Figure 248 VPN/NAT Example
If router A does NAT, it might change the IP addresses, port numbers, or both. If router X and
router Y try to establish a VPN tunnel, the authentication fails because it depends on this
information. The routers cannot establish a VPN tunnel.
Most routers like router A now have an IPSec pass-thru feature. This feature helps router A
recognize VPN packets and route them appropriately. If router A has this feature, router X and
router Y can establish a VPN tunnel as long as the active protocol is ESP. (See Active Protocol on
page 359 for more information about active protocols.)
If router A does not have an IPSec pass-thru or if the active protocol is AH, you can solve this
problem by enabling NAT traversal. In NAT traversal, router X and router Y add an extra header to
the IKE SA and IPSec SA packets. If you configure router A to forward these packets unchanged,
router X and router Y can establish a VPN tunnel.
You have to do the following things to set up NAT traversal.
• Enable NAT traversal on the UAG and remote IPSec router.
• Configure the NAT router to forward packets with the extra header unchanged. (See the field
description for detailed information about the extra header.)
The extra header may be UDP port 500 or UDP port 4500, depending on the standard(s) the UAG
and remote IPSec router support.
Extended Authentication
Extended authentication is often used when multiple IPSec routers use the same VPN tunnel to
connect to a single IPSec router. For example, this might be used with telecommuters.
A
XY
Chapter 30 IPSec VPN
UAG Series User’s Guide
359
In extended authentication, one of the routers (the UAG or the remote IPSec router) provides a
user name and password to the other router, which uses a local user database and/or an external
server to verify the user name and password. If the user name or password is wrong, the routers
do not establish an IKE SA.
You can set up the UAG to provide a user name and password to the remote IPSec router, or you
can set up the UAG to check a user name and password that is provided by the remote IPSec
router.
If you use extended authentication, it takes four more steps to establish an IKE SA. These steps
occur at the end, regardless of the negotiation mode (steps 7-10 in main mode, steps 4-7 in
aggressive mode).
Certificates
It is possible for the UAG and remote IPSec router to authenticate each other with certificates. In
this case, you do not have to set up the pre-shared key, local identity, or remote identity because
the certificates provide this information instead.
• Instead of using the pre-shared key, the UAG and remote IPSec router check the signatures on
each other’s certificates. Unlike pre-shared keys, the signatures do not have to match.
• The local and peer ID type and content come from the certificates.
Note: You must set up the certificates for the UAG and remote IPSec router first.
IPSec SA Overview
Once the UAG and remote IPSec router have established the IKE SA, they can securely negotiate an
IPSec SA through which to send data between computers on the networks.
Note: The IPSec SA stays connected even if the underlying IKE SA is not available
anymore.
This section introduces the key components of an IPSec SA.
Local Network and Remote Network
In an IPSec SA, the local network, the one(s) connected to the UAG, may be called the local policy.
Similarly, the remote network, the one(s) connected to the remote IPSec router, may be called the
remote policy.
Active Protocol
The active protocol controls the format of each packet. It also specifies how much of each packet is
protected by the encryption and authentication algorithms. IPSec VPN includes two active
protocols, AH (Authentication Header, RFC 2402) and ESP (Encapsulating Security Payload, RFC
2406).
Note: The UAG and remote IPSec router must use the same active protocol.
Usually, you should select ESP. AH does not support encryption, and ESP is more suitable with NAT.
Chapter 30 IPSec VPN
UAG Series User’s Guide
360
Encapsulation
There are two ways to encapsulate packets. Usually, you should use tunnel mode because it is more
secure. Transport mode is only used when the IPSec SA is used for communication between the
UAG and remote IPSec router (for example, for remote management), not between computers on
the local and remote networks.
Note: The UAG and remote IPSec router must use the same encapsulation.
These modes are illustrated below.
In tunnel mode, the UAG uses the active protocol to encapsulate the entire IP packet. As a result,
there are two IP headers:
• Outside header: The outside IP header contains the IP address of the UAG or remote IPSec
router, whichever is the destination.
• Inside header: The inside IP header contains the IP address of the computer behind the UAG or
remote IPSec router. The header for the active protocol (AH or ESP) appears between the IP
headers.
In transport mode, the encapsulation depends on the active protocol. With AH, the UAG includes
part of the original IP header when it encapsulates the packet. With ESP, however, the UAG does
not include the IP header when it encapsulates the packet, so it is not possible to verify the
integrity of the source IP address.
IPSec SA Proposal and Perfect Forward Secrecy
An IPSec SA proposal is similar to an IKE SA proposal (see IKE SA Proposal on page 354), except
that you also have the choice whether or not the UAG and remote IPSec router perform a new DH
key exchange every time an IPSec SA is established. This is called Perfect Forward Secrecy (PFS).
If you enable PFS, the UAG and remote IPSec router perform a DH key exchange every time an
IPSec SA is established, changing the root key from which encryption keys are generated. As a
result, if one encryption key is compromised, other encryption keys remain secure.
If you do not enable PFS, the UAG and remote IPSec router use the same root key that was
generated when the IKE SA was established to generate encryption keys.
The DH key exchange is time-consuming and may be unnecessary for data that does not require
such security.

Additional Topics for IPSec SA
This section provides more information about IPSec SA in your UAG.
NAT for Inbound and Outbound Traffic
The UAG can translate the following types of network addresses in IPSec SA.
• Source address in outbound packets - this translation is necessary if you want the UAG to route
packets from computers outside the local network through the IPSec SA.
• Source address in inbound packets - this translation hides the source address of computers in the
remote network.
• Destination address in inbound packets - this translation is used if you want to forward packets
(for example, mail) from the remote network to a specific computer (like the mail server) in the
local network.
Each kind of translation is explained below. The following example is used to help explain each one.
Figure 250 VPN Example: NAT for Inbound and Outbound Traffic
Source Address in Outbound Packets (Outbound Traffic, Source NAT)
This translation lets the UAG route packets from computers that are not part of the specified local
network (local policy) through the IPSec SA. For example, in Figure 250 on page 361, you have to
configure this kind of translation if you want computer M to establish a connection with any
computer in the remote network (B). If you do not configure it, the remote IPSec router may not
route messages for computer M through the IPSec SA because computer M’s IP address is not part
of its local policy.
To set up this NAT, you have to specify the following information:
• Source - the original source address; most likely, computer M’s network.
Chapter 30 IPSec VPN
UAG Series User’s Guide
362
• Destination - the original destination address; the remote network (B).
• SNAT - the translated source address; the local network (A).
Source Address in Inbound Packets (Inbound Traffic, Source NAT)
You can set up this translation if you want to change the source address of computers in the remote
network. To set up this NAT, you have to specify the following information:
• Source - the original source address; the remote network (B).
• Destination - the original destination address; the local network (A).
• SNAT - the translated source address; a different IP address (range of addresses) to hide the
original source address.
Destination Address in Inbound Packets (Inbound Traffic, Destination NAT)
You can set up this translation if you want the UAG to forward some packets from the remote
network to a specific computer in the local network. For example, in Figure 250 on page 361, you
can configure this kind of translation if you want to forward mail from the remote network to the
mail server in the local network (A).
You have to specify one or more rules when you set up this kind of NAT. The UAG checks these rules
similar to the way it checks security policies. The first part of these rules define the conditions in
which the rule apply.
• Original IP - the original destination address; the remote network (B).
• Protocol - the protocol [TCP, UDP, or both] used by the service requesting the connection.
• Original Port - the original destination port or range of destination ports; in Figure 250 on page
361, it might be port 25 for SMTP.
The second part of these rules controls the translation when the condition is satisfied.
• Mapped IP - the translated destination address; in Figure 250 on page 361, the IP address of the
mail server in the local network (A).
• Mapped Port - the translated destination port or range of destination ports.
The original port range and the mapped port range must be the same size.

CHAPTER 31
Bandwidth Management
31.1 Overview
Bandwidth management provides a convenient way to manage the use of various services on the
network. It manages general protocols (for example, HTTP and FTP) and applies traffic prioritization
to enhance the performance of delay-sensitive applications like voice and video.
31.1.1 What You Can Do in this Chapter
Use the BWM screens (see Section 31.2 on page 370) to control bandwidth for services passing
through the UAG, and it identifies the conditions that refine this.
31.1.2 What You Need to Know
When you allow a service, you can restrict the bandwidth it uses. It controls TCP and UDP traffic.
Use policy routes to manage other types of traffic (like ICMP).
Note: Bandwidth management in policy routes has priority over TCP and UDP traffic
policies.
If you want to use a service, make sure both the security policy allow the service’s packets to go
through the UAG.
Note: The UAG checks security policies before it checks bandwidth management rules for
traffic going through the UAG.
Bandwidth management examines every TCP and UDP connection passing through the UAG. Then,
you can specify, by port, whether or not the UAG continues to route the connection.
BWM Type
The UAG supports three types of bandwidth management: Shared, Per user and Per-Source-IP.
The Shared BWM type is selected by default in a bandwidth management rule. All matched taffic
shares the bandwidth configured in the rule.
If the BWM type is set to Per us er in a rule, each user that matches the rule can use up to the
configured bandwidth by his/her own.
Select the Per-Source-IP type when you want to set the maximum bandwidth for traffic from an
individual source IP address.
In the following example, you configure a Per user bandwidth management rule for billing-users to
limit outgoing traffic to 300 kbs. Then all billing-users (A, B and C) can send 300 kbps of traffic.
Chapter 31 Bandwidth Management
UAG Series User’s Guide
367
DiffServ and DSCP Marking
QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given
the same priority. CoS (class of service) is a way of managing traffic in a network by grouping
similar types of traffic together and treating each type as a class. You can use CoS to give different
priorities to different packet types.
DiffServ (Differentiated Services) is a class of service (CoS) model that marks packets so that they
receive specific per-hop treatment at DiffServ-compliant network devices along the route based on
the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs)
indicating the level of service desired. This allows the intermediary DiffServ-compliant network
devices to handle the packets differently depending on the code points without the need to
negotiate paths or remember state information for every flow. In addition, applications do not have
to request a particular service or give advanced notice of where the traffic is going.
Connection and Packet Directions
Bandwidth management looks at the connection direction, that is from which interface the
connection was initiated and to which interface the connection is going.
A connection has outbound and inbound packet flows. The UAG controls the bandwidth of traffic of
each flow as it is going out through an interface.
• The outbound traffic flows from the connection initiator to the connection responder.
• The inbound traffic flows from the connection responder to the connection initiator.
For example, a LAN1 to WAN connection is initiated from LAN1 and goes to the WAN.
• Outbound traffic goes from a LAN1 device to a WAN device. Bandwidth management is applied
before sending the packets out a WAN interface on the UAG.
• Inbound traffic comes back from the WAN device to the LAN1 device. Bandwidth management is
applied before sending the traffic out a LAN1 interface.
Chapter 31 Bandwidth Management
UAG Series User’s Guide
368
Figure 252 LAN1 to WAN Connection and Packet Directions
Outbound and Inbound Bandwidth Limits
You can limit an application’s outbound or inbound bandwidth. This limit keeps the traffic from using
up too much of the out-going interface’s bandwidth. This way you can make sure there is bandwidth
for other applications. When you apply a bandwidth limit to outbound or inbound traffic, each
member of the out-going zone can send up to the limit. Take a LAN1 to WAN policy for example.
• Outbound traffic is limited to 200 kbps. The connection initiator is on the LAN1 so outbound
means the traffic traveling from the LAN1 to the WAN. Each of the WAN zone’s two interfaces can
send the limit of 200 kbps of traffic.
• Inbound traffic is limited to 500 kbs. The connection initiator is on the LAN1 so inbound means
the traffic traveling from the WAN to the LAN1.
Figure 253 LAN1 to WAN, Outbound 200 kbps, Inbound 500 kbps
Bandwidth Management Priority
• The UAG gives bandwidth to higher-priority traffic first, until it reaches its configured bandwidth
rate.
• Then lower-priority traffic gets bandwidth.
• The UAG uses a fairness-based (round-robin) scheduler to divide bandwidth among traffic flows
with the same priority.
• The UAG automatically treats traffic with bandwidth management disabled as priority 7 (the
lowest priority).

Maximize Bandwidth Usage
Maximize bandwidth usage allows applications with maximize bandwidth usage enabled to “borrow”
any unused bandwidth on the out-going interface.
After each application gets its configured bandwidth rate, the UAG uses the fairness- based
scheduler to divide any unused bandwidth on the out-going interface amongst applications that
need more bandwidth and have maximize bandwidth usage enabled.
Unused bandwidth is divided equally. Higher priority traffic does not get a larger portion of the
unused bandwidth.
Bandwidth Management Behavior
The following sections show how bandwidth management behaves with various settings. For
example, you configure LAN1 to WAN policies for FTP servers A and B. Each server tries to send
1000 kbps, but the WAN is set to a maximum outgoing speed of 1000 kbps. You configure policy A
for server A’s traffic and policy B for server B’s traffic.
Figure 254 Bandwidth Management Behavior
Configured Rate Effect
In the following table the configured rates total less than the available bandwidth and maximize
bandwidth usage is disabled, both servers get their configured rate.
Priority Effect
Here the configured rates total more than the available bandwidth. Because server A has higher
priority, it gets up to it’s configured rate (800 kbps), leaving only 200 kbps for server B.
Table 161 Configured Rate Effect

Maximize Bandwidth Usage Effect
With maximize bandwidth usage enabled, after each server gets its configured rate, the rest of the
available bandwidth is divided equally between the two. So server A gets its configured rate of 300
kbps and server B gets its configured rate of 200 kbps. Then the UAG divides the remaining
bandwidth (1000 - 500 = 500) equally between the two (500 / 2 = 250 kbps for each). The priority
has no effect on how much of the unused bandwidth each server gets.
So server A gets its configured rate of 300 kbps plus 250 kbps for a total of 550 kbps. Server B
gets its configured rate of 200 kbps plus 250 kbps for a total of 450 kbps.
Priority and Over Allotment of Ban dwidth Effect
Server A has a configured rate that equals the total amount of available bandwidth and a higher
priority. You should regard extreme over allotment of traffic with different priorities (as shown here)
as a configuration error. Even though the UAG still attempts to let all traffic get through and not be
lost, regardless of its priority, server B gets almost no bandwidth with this configuration.
Finding Out More
•See DSCP Marking and Per-Hop Behavior on page 205 for a description of DSCP marking.
31.2 The Bandwidth Management Screen
The Bandwidth management screens control the bandwidth allocation for TCP and UDP traffic. You
can use source interface, destination interface, destination port, schedule, user, source, destination
information, DSCP code and service type as criteria to create a sequence of specific conditions,
similar to the sequence of security policies, to specify how the UAG handles the DSCP value and
allocate bandwidth for the matching packets.
Click Configuration > BWM to open the following screen. This screen allows you to enable/disable
bandwidth management and add, edit, and remove user-defined bandwidth management policies.
The default bandwidth management policy is the one with the priority of “default”. It is the last
policy the UAG checks if traffic does not match any other bandwidth management policies you have
configured. You cannot remove, activate, deactivate or move the default bandwidth management
policy.

BWM In/Pri/Out/
Pri
This field shows the amount of bandwidth the traffic can use.
In - This is how much inbound bandwidth, in kilobits per second, this policy allows the
matching traffic to use. Inbound refers to the traffic the UAG sends to a connection’s
initiator. If no displays here, this policy does not apply bandwidth management for the
inbound traffic.
Out - This is how much outgoing bandwidth, in kilobits per second, this policy allows the
matching traffic to use. Outbound refers to the traffic the UAG sends out from a
connection’s initiator. If no displays here, this policy does not apply bandwidth
management for the outbound traffic.
Pri - This is the priority for the incoming (the first Pri value) or outgoing (the second Pri
value) traffic that matches this policy. The smaller the number, the higher the priority.
Traffic with a higher priority is given bandwidth before traffic with a lower priority. The UAG
ignores this number if the incoming and outgoing limits are both set to 0. In this case the
traffic is automatically treated as being set to the lowest priority (7) regardless of this
field’s configuration.
DSCP Marking This is how the UAG handles the DSCP value of the incoming and outgoing packets that
match this policy.
preserve means the UAG does not modify the DSCP value of the route’s packets.
default means the UAG sets the DSCP value of the route’s packets to 0.
If this field displays a DSCP value, the UAG applies that DSCP value to the route’s packets.

Inbound
kbps Type how much inbound bandwidth, in kilobits per second, this policy allows the traffic to
use. Inbound refers to the traffic the UAG sends to a connection’s initiator.
If you enter 0 here, this policy does not apply bandwidth management for the matching
traffic that the UAG sends to the initiator. Traffic with bandwidth management disabled
(inbound and outbound are both set to 0) is automatically treated as the lowest priority
(7).
If the sum of the bandwidths for routes using the same next hop is higher than the actual
transmission speed, lower priority traffic may not be sent if higher priority traffic uses all of
the actual bandwidth.
Outbound
kbps Type how much outbound bandwidth, in kilobits per second, this policy allows the traffic to
use. Outbound refers to the traffic the UAG sends out from a connection’s initiator.
If you enter 0 here, this policy does not apply bandwidth management for the matching
traffic that the UAG sends out from the initiator. Traffic with bandwidth management
disabled (inbound and outbound are both set to 0) is automatically treated as the lowest

the actual bandwidth.
Priority Enter a number between 1 and 7 to set the priority for traffic that matches this policy. The
smaller the number, the higher the priority.
Traffic with a higher priority is given bandwidth before traffic with a lower priority.
The UAG uses a fairness-based (round-robin) scheduler to divide bandwidth between
traffic flows with the same priority.
The number in this field is ignored if the incoming and outgoing limits are both set to 0. In
this case the traffic is automatically treated as being set to the lowest priority (7)
regardless of this field’s configuration.

CHAPTER 32
Application Patrol
32.1 Overview
Application patrol provides a convenient way to manage the use of various applications on the
network. It manages general protocols (for example, HTTP and FTP) and instant messenger (IM),
peer-to-peer (P2P), Voice over IP (VoIP), and streaming (RSTP) applications. You can even control
the use of a particular application’s individual features (like text messaging, voice, video
conferencing, and file transfers). You can also configure bandwidth management with application
patrol in the Configuration > BWM screen for traffic prioritization to enhance the performance of
delay-sensitive applications like voice and video.
32.1.1 What You Can Do in this Chapter
•Use the Profile summary screen (see Section 32.2 on page 377) to view application patrol
profiles configured on the UAG.
•Use the Profile Add/Edit screens (see Section 32.2.1 on page 378) to set actions for application
categories and for specific applications within the category.
32.1.2 What You Need to Know
If you want to use a service, make sure both the Security Policy and application patrol allow the
service’s packets to go through the UAG.
Note: The UAG checks secure policies before it checks application patrol rules for traffic
going through the UAG.
Application patrol examines every TCP and UDP connection passing through the UAG and identifies
what application is using the connection. Then, you can specify whether or not the UAG continues
to route the connection. Traffic not recognized by the application patrol signatures is ignored.
Application Profiles & Policies
An application patrol profile is a group of categories of application patrol signatures. For each
profile, you can specify the default action the UAG takes once a packet matches a signature
(forward, drop, or reject a service’s connections and/or create a log alert).
Use policies to link profiles to traffic flows based on criteria such as source zone, destination zone,
source address, destination address, schedule, user.
Classification of Applications
There are two ways the UAG can identify the application. The first is called auto. The UAG looks at
the IP payload (OSI level-7 inspection) and attempts to match it with known patterns for specific
Chapter 32 Application Patrol
UAG Series User’s Guide
377
applications. Usually, this occurs at the beginning of a connection, when the payload is more
consistent across connections, and the UAG examines several packets to make sure the match is
correct. Before confirmation, packets are forwarded by App Patrol with no action taken. The number
of packets inspected before confirmation varies by signature.
Note: The UAG allows the first eight packets to go through the security policy, regardless
of the application patrol policy for the application. The UAG examines these first
eight packets to identify the application.
The second approach is called service ports. The UAG uses only OSI level-4 information, such as
ports, to identify what application is using the connection. This approach is available in case the
UAG identifies a lot of “false positives” for a particular application.
Custom Ports for SIP and the SIP ALG
Configuring application patrol to use custom port numbers for SIP traffic also configures the SIP
ALG to use the same port numbers for SIP traffic. Likewise, configuring the SIP ALG to use custom
port numbers for SIP traffic also configures application patrol to use the same port numbers for SIP
traffic.
Finding Out More
• You must configure services in Objects > Application.
•See Configuration > BWM chapter for detailed information on bandwidth management.
32.2 Application Patrol Profile
Use the application patrol Profile screens to customize action and log settings for a group of
application patrol signatures. You then link a profile to a security policy (see Section 25.2 on page
291).
Note: You must register for the AppPatrol signature service (at least the trial) before you
can use it.
A profile is an application object(s) or application group(s) that has customized action and log
settings.

CHAPTER 33
Content Filtering
33.1 Overview
Use the content filtering feature to control access to specific web sites or web content.
33.1.1 What You Can Do in this Chapter
•Use the Profile screens (Section 33.2 on page 383) to set up content filtering profiles.
•Use the Trusted Web Sites screens (Section 33.3 on page 391) to create a common list of good
(allowed) web site addresses.
•Use the Forbidden Web Sites screens (Section 33.4 on page 392) to create a common list of
bad (blocked) web site addresses.
33.1.2 What You Need to Know
Content Filtering
Content filtering allows you to block certain web features, such as cookies, and/or block access to
specific web sites. It can also block access to specific categories of web site content. You can create
different content filter policies for different addresses, schedules, users or groups and content filter
profiles. For example, you can configure one policy that blocks John Doe’s access to arts and
entertainment web pages during the workday and another policy that lets him access them after
work.
Content Filtering Policies
A content filtering policy allows you to do the following.
• Use schedule objects to define when to apply a content filter profile.
• Use address and/or user/group objects to define to whose web access to apply the content filter
profile.
• Apply a content filter profile that you have custom-tailored.
Content Filtering Profiles
A content filtering profile conveniently stores your custom settings for the following features.
• Category-based Blocking
The UAG can block access to particular categories of web site content, such as pornography or
racial intolerance.
Chapter 33 Content Filtering
UAG Series User’s Guide
382
• Restrict Web Features
The UAG can disable web proxies and block web features such as ActiveX controls, Java applets
and cookies.
• Customize Web Site Access
You can specify URLs to which the UAG blocks access. You can alternatively block access to all
URLs except ones that you specify. You can also have the UAG block access to URLs that contain
particular keywords.
Content Filtering Configuration Guidelines
When the UAG receives an HTTP request, the content filter searches for a policy that matches the
source address and time (schedule). The content filter checks the policies in order (based on the
policy numbers). When a matching policy is found, the content filter allows or blocks the request
depending on the settings of the filtering profile specified by the policy. Some requests may not
match any policy. The UAG allows the request if the default policy is not set to block. The UAG
blocks the request if the default policy is set to block.
External Web Filtering Service
When you register for and enable the external web filtering service, your UAG accesses an external
database that has millions of web sites categorized based on content. You can have the UAG block,
block and/or log access to web sites based on these categories.
Keyword Blocking URL Checking
The UAG checks the URL’s domain name (or IP address) and file path separately when performing
keyword blocking.
The URL’s domain name or IP address is the characters that come before the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is
www.zyxel.com.tw.
The file path is the characters that come after the first slash in the URL. For example, with the URL
www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.
Since the UAG checks the URL’s domain name (or IP address) and file path separately, it will not
find items that go across the two. For example, with the URL www.zyxel.com.tw/news/
pressroom.php, the UAG would find “tw” in the domain name (www.zyxel.com.tw). It would also
find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.
Finding Out More
•See Section 33.5 on page 393 for content filtering background/technical information.
33.1.3 Before You Begin
• You must configure an address object, a schedule object and a filtering profile before you can set
up a content security policy.
• You must have Content Filtering license in order to use the function.subscribe to use the external
database content filtering (see the Licensing > Registration screens).

ActiveX
ActiveX is a tool for building dynamic and active web pages and distributed
object applications. When you visit an ActiveX web site, ActiveX controls are
downloaded to your browser, where they remain in case you visit the site
again.
Java Java is a programming language and development environment for building
downloadable Web components or Internet and intranet business
applications of all kinds.
Cookies Cookies are files stored on a computer’s hard drive. Some web servers use
them to track usage and provide service based on ID.
Web Proxy A server that acts as an intermediary between a user and the Internet to
provide security, administrative control, and caching service. When a proxy
server is located on the WAN it is possible for LAN users to circumvent
content filtering by pointing to this proxy server.

Figure 266 Content Filter Lookup Procedure
1A computer behind the UAG tries to access a web site.
2The UAG looks up the web site in its cache. If an attempt to access the web site was made in the
past, a record of that web site’s category will be in the UAG’s cache. The UAG blocks, blocks and
logs or just logs the request based on your configuration.
3If the UAG has no record of the web site, it queries the external content filter database and
simultaneously sends the request to the web server.
4The external content filter server sends the category information back to the UAG, which then
blocks and/or logs access to the web site based on the settings in the content filter profile. The web
site’s address and category are then stored in the UAG’s content filter cache.

CHAPTER 34
Zones
34.1 Zones Overview
Set up zones to configure network security and network policies in the UAG. A zone is a group of
interfaces. The UAG uses zones instead of interfaces in many security and policy settings, such as
security policies and remote management.
Zones cannot overlap. Each Ethernet interface, VLAN interface, bridge interface, and PPPoE/PPTP
interface can be assigned to at most one zone. Virtual interfaces are automatically assigned to the
same zone as the interface on which they run.
Figure 267 Example: Zones
34.1.1 What You Can Do in this Chapter
Use the Zone screens (see Section 34.2 on page 396) to manage the UAG’s zones.
34.1.2 What You Need to Know
Effects of Zones on Different Types of Traffic
Zones effectively divide traffic into three types--intra-zone traffic, inter-zone traffic, and extra-zone
traffic--which are affected differently by zone-based security and policy settings.
Chapter 34 Zones
UAG Series User’s Guide
396
Intra-zone Traffic
• Intra-zone traffic is traffic between interfaces in the same zone. For example, in Figure 267 on
page 395, traffic between VLAN1 and the Ethernet is intra-zone traffic.
• You can also set up security policies to control intra-zone traffic (for example, LAN1-to-LAN1),
but many other types of zone-based security and policy settings do not affect intra-zone traffic.
Inter-zone Traffic
Inter-zone traffic is traffic between interfaces in different zones. For example, in Figure 267 on page
395, traffic between VLAN1 and the Internet is inter-zone traffic. This is the normal case when
zone-based security and policy settings apply.
Extra-zone Traffic
• Extra-zone traffic is traffic to or from any interface that is not assigned to a zone. For example, in
Figure 267 on page 395, traffic to or from computer C is extra-zone traffic.
• Some zone-based security and policy settings may apply to extra-zone traffic, especially if you
can set the zone attribute in them to Any or All. See the specific feature for more information.

The Zone screen provides a summary of all zones. In addition, this screen allows you to add, edit,

CHAPTER 35
User/Group
35.1 Overview
This chapter describes how to set up user accounts, user groups, and user settings for the UAG. You
can also set up rules that control when users have to log in to the UAG before the UAG routes traffic
for them.
35.1.1 What You Can Do in this Chapter
•The User screen (see Section 35.2 on page 401) provides a summary of all user accounts.
•The Group screen (see Section 35.3 on page 405) provides a summary of all user groups. In
addition, this screen allows you to add, edit, and remove user groups. User groups may consist of
access users and other user groups. You cannot put admin users in user groups
•The Setting screen (see Section 35.4 on page 406) controls default settings, login settings,
lockout settings, and other user settings for the UAG. You can also use this screen to specify
when users must log in to the UAG before it routes traffic for them.
•The MAC Address screen (see Section 35.5 on page 411) allows you to configure the MAC
addresses of wireless clients for MAC authentication using the local user database.
35.1.2 What You Need To Know
User Account
A user account defines the privileges of a user logged into the UAG. User accounts are used in
security policies and application patrol, in addition to controlling access to configuration and
services in the UAG.
User Types
These are the types of user accounts the UAG uses.

Chapter 35 User/Group
UAG Series User’s Guide
400
Note: The default admin account is always authenticated locally, regardless of the
authentication method setting. (See Chapter 43 on page 464 for more information
about authentication methods.)
Ext-User Accounts
Set up an ext-user account if the user is authenticated by an external server and you want to set
up specific policies for this user in the UAG. If you do not want to set up policies for this user, you
do not have to set up an ext-user account.
All ext-user users should be authenticated by an external server, such as RADIUS. If the UAG tries
to use the local database to authenticate an ext-user, the authentication attempt always fails.
(This is related to AAA servers and authentication methods, which are discussed in Chapter 42 on
page 459 and Chapter 43 on page 464, respectively.)
Note: If the UAG tries to authenticate an ext-user using the local database, the attempt
always fails.
Once an ext-user user has been authenticated, the UAG tries to get the user type (see Table 177
on page 399) from the external server. If the external server does not have the information, the
UAG sets the user type for this session to User.
For the rest of the user attributes, such as reauthentication time, the UAG checks the following
places, in order.
1User account in the remote server.
2User account (Ext-User) in the UAG.
3Default user account for RADIUS users (radius-users) in the UAG.
See Setting up User Attributes in an External Server on page 413 for a list of attributes and how to
set up the attributes in an external server.
Ext-Group-User Accounts
Ext-Group-User accounts are similar to ext-user accounts but allow you to group users by the
value of the group membership attribute configured for the RADIUS server. See Section 42.2.1 on
page 460 for more on the group membership attribute.
Dynamic-Guest Accounts
Dynamic guest accounts are guest accounts, but are created dynamically and stored in the UAG’s
local user database. A dynamic guest account has a dynamically-created user name and password.
A dynamic guest account user can access the UAG’s services only within a given period of time and
will become invalid after the expiration date/time.

Table 177 Types of User Accounts (continued)
TYPE ABILITIES LOGIN METHOD(S)
Chapter 35 User/Group
UAG Series User’s Guide
401
There are three types of dynamic guest accounts depending on how they are created or
authenticated: billing-users, ua-users and trial-users.
billing-users are guest account created with the guest manager account or an external printer and
paid by cash or created and paid via the on-line payment service. ua-users are users that log in
from the user agreement page. trial-users are free guest accounts that are created with the Free
Time function.
Pre-Subscriber Accounts
Use the pre-subscriber account to test the Internet connection between the UAG and the ISP. The
UAG does not impose time limitations or charges on this account. Thus, anyone who logs in with
this account is able to gain Internet access for free.
User Groups
User groups may consist of user accounts or other user groups. Use user groups when you want to
create the same rule for several user accounts, instead of creating separate rules for each one.
Note: You cannot put access users and admin users in the same user group.
Note: You cannot put the default admin account into any user group.
The sequence of members in a user group is not important.
User Awareness
By default, users do not have to log into the UAG to use the network services it provides. The UAG
automatically routes packets for everyone. If you want to restrict network services that certain
users can use via the UAG, you can require them to log in to the UAG first. The UAG is then ‘aware’
of the user who is logged in and you can create ‘user-aware policies’ that define what services they
can use. See Section 35.4.2 on page 410 for a user-aware login example.
Finding Out More
•See Section 35.6 on page 413 for some information on users who use an external authentication
server in order to log in.

CHAPTER 36
AP Profile
36.1 Overview
This chapter shows you how to configure preset profiles for the Access Points (APs) connected to
your UAG’s wireless network.
36.1.1 What You Can Do in this Chapter
•The Radio screen (Section 36.2 on page 415) creates radio configurations that can be used by
the APs.
•The SSID screen (Section 36.3 on page 420) configures three different types of profiles for your
networked APs.
36.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
Wireless Profiles
At the heart of all wireless AP configurations on the UAG are profiles. A profile represents a group of
saved settings that you can use across any number of connected APs. You can set up the following
wireless profile types:
•Radio - This profile type defines the properties of an AP’s radio transmitter. You can have a
maximum of 32 radio profiles on the UAG2100 and the UAG4100, or 64 radio profiles on the
UAG5100.
•SSID - This profile type defines the properties of a single wireless network signal broadcast by
an AP. Each radio on a single AP can broadcast up to 8 SSIDs. You can have a maximum of 32
SSID profiles on the UAG2100 and the UAG4100, or 64 SSID profiles on the UAG5100.
•Security - This profile type defines the security settings used by a single SSID. It controls the
encryption method required for a wireless client to associate itself with the SSID. You can have a
maximum of 32 security profiles on the UAG2100 and the UAG4100, or 64 security profiles on
the UAG5100.
•MAC Filtering - This profile provides an additional layer of security for an SSID, allowing you to
block access or allow access to that SSID based on wireless client MAC addresses. If a client’s
MAC address is on the list, then it is either allowed or denied, depending on how you set up the
MAC Filter profile. You can have a maximum of 32 MAC filtering profiles on the UAG2100 and the
UAG4100, or 64 MAC filtering profiles on the UAG5100.
Chapter 36 AP Profile
UAG Series User’s Guide
415
SSID
The SSID (Service Set IDentifier) is the name that identifies the Service Set with which a wireless
station is associated. Wireless stations associating to the access point (AP) must have the same
SSID. In other words, it is the name of the wireless network that clients use to connect to it.
WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the AP
and the wireless stations associated with it in order to keep network communications private. Both
the wireless stations and the access points must use the same WEP key for data encryption and
decryption.
WPA and WPA2
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a
wireless security standard that defines stronger encryption, authentication and key management
than WPA. Key differences between WPA(2) and WEP are improved data encryption and user
authentication.
IEEE 802.1x
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of
wireless stations and encryption key management. Authentication is done using an external
RADIUS server.
36.2 Radio Screen
This screen allows you to create radio profiles for the APs on your network. A radio profile is a list of
settings that a supported managed AP (NWA5121-N for example) can use to configure either one of
its two radio transmitters. To access this screen click Configuration > Object > AP Profile.

compliant WLAN devices associate with the AP.
When using the 2.4 GHz band, select b/g/n to let IEEE 802.11b, IEEE 802.11g, and
IEEE 802.11n compliant WLAN devices associate with the AP.
When using the 5 GHz band, select a to let only IEEE 802.11a compliant WLAN devices
associate with the AP.
When using the 5 GHz band, select a/n to let IEEE 802.11a and IEEE 802.11n
compliant WLAN devices associate with the AP.
Channel Select the wireless channel which this radio profile should use.
It is recommended that you choose the channel least in use by other APs in the region
where this profile will be implemented. This will reduce the amount of interference
between wireless clients and the AP to which this profile is assigned.
Some 5 GHz channels include the label indoor use only. These are for use with an
indoor AP only. Do not use them with an outdoor AP.
Schedule Select a schedule to control when the WLAN of the managed AP (to which this radio
profile is applied) is turned on. Otherwise, select none and the managed AP’s WLAN is
always enabled.
Advanced Settings
Channel Width Select the channel bandwidth you want to use for your wireless network.
Select Auto to allow the UAG to adjust the channel bandwidth to 40 MHz or 20 MHz
depending on network conditions.
Select 20 MHz if you want to lessen radio interference with other wireless devices in
your neighborhood.
Guard Interval Set the guard interval for this radio profile to either short or long.
The guard interval is the gap introduced between data transmission from users in order
to reduce interference. Reducing the interval increases data transfer rates but also
increases interference. Increasing the interval reduces data transfer rates but also
reduces interference.
Enable A-MPDU
Aggregation Select this to enable A-MPDU aggregation.
Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with
their 802.11n headers and wraps them in a 802.11n MAC header. This method is useful
for increasing bandwidth throughput in environments that are prone to high error
rates.
Chapter 36 AP Profile
UAG Series User’s Guide
419
A-MPDU Limit Enter the maximum frame size to be aggregated.
A-MPDU
Subframe Enter the maximum number of frames to be aggregated each time.
Enable A-MSDU
Aggregation Select this to enable A-MSDU aggregation.
Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of
their 802.11n headers and wraps the header-less payload in a single 802.11n MAC
header. This method is useful for increasing bandwidth throughput. It is also more
efficient than A-MPDU except in environments that are prone to high error rates.
A-MSDU Limit Enter the maximum frame size to be aggregated.
RTS/CTS
Threshold Use RTS/CTS to reduce data collisions on the wireless network if you have wireless
clients that are associated with the same AP but out of range of one another. When
enabled, a wireless client sends an RTS (Request To Send) and then waits for a CTS
(Clear To Send) before it transmits. This stops wireless clients from transmitting
packets at the same time (and causing data collisions).
A wireless client sends an RTS for all packets larger than the number (of bytes) that
you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold
to turn RTS/CTS off.
Beacon Interval When a wirelessly networked device sends a beacon, it includes with it a beacon
interval. This specifies the time period before the device sends the beacon again. The
interval tells receiving devices on the network how long they can wait in low-power
mode before waking up to handle the beacon. A high value helps save current
consumption of the access point.
DTIM Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and
multicast packets are transmitted to mobile clients in the Active Power Management
mode. A high DTIM value can cause clients to lose connectivity with the network. This
value can be set from 1 to 255.
Output Power Set the output power of the AP in this field. If there is a high density of APs in an area,
decrease the output power of the NWA5160N to reduce interference with other APs.
Select one of the following Max, -3dB (50%), -6dB (25%), -9dB (12.5%), or Min.
See the product specifications for more information on your UAG’s output power.
Note: Reducing the output power also reduces the UAG’s effective broadcast radius.
Enable Signal
Threshold Select the check box to use the signal threshold to ensure wireless clients receive good
throughput. This allows only wireless clients with a strong signal to connect to the AP.
Clear the check box to not require wireless clients to have a minimum signal strength
to connect to the AP.
Station Signal
Threshold Set a minimum client signal strength. A wireless client is allowed to connect to the AP
only when its signal strength is stronger than the specified threshold.
-20 dBm is the strongest signal you can require and -76 is the weakest.
Disassociate
Station
Threshold
Set a minimum kick-off signal strength. When a wireless client’s signal strength is
lower than the specified threshold, the UAG disconnects the wireless client from the AP.
-20 dBm is the strongest signal you can require and -90 is the weakest.
Allow Station
Connection after
Multiple Retries
Select this option to allow a wireless client to try to associate with the AP again after it
is disconnected due to weak signal strength.
Station Retry
Count Set the maximum number of times a wireless client can attempt to re-connect to the
AP

36.3 SSID Screen
The SSID screens allow you to configure three different types of profiles for your networked APs: an
SSID list, which can assign specific SSID configurations to your APs; a security list, which can
assign specific encryption methods to the APs when allowing wireless clients to connect to them;
and a MAC filter list, which can limit connections to an AP based on wireless clients MAC addresses.
36.3.1 SSID List
This screen allows you to create and manage SSID configurations that can be used by the APs. An
SSID, or Service Set IDentifier, is basically the name of the wireless network to which a wireless
client can connect. The SSID appears as readable text to any device capable of scanning for
wireless frequencies (such as the WiFi adapter in a laptop), and is displayed as the wireless network
name when a person makes a connection to it.
Rate Configuration This section controls the data rates permitted for clients.
For each Rate, select a rate option from its list. The rates are:
•Basic Rate (Mbps) - Set the basic rate configuration in Mbps.
•Support Rate (Mbps) - Set the support rate configuration in Mbps.
•MCS Rate - Set the MCS rate configuration. IEEE 802.11n supports many different
data rates which are called MCS rates. MCS stands for Modulation and Coding
Scheme. This is an 802.11n feature that increases the wireless network
performance in terms of throughput.
Multicast Settings Use this section to set a transmission mode and maximum rate for multicast traffic.
Transmission
Mode Set how the AP handles multicast traffic.
Select Multicast to Unicast to broadcast wireless multicast traffic to all of the wireless
clients as unicast traffic. Unicast traffic dynamically changes the data rate based on the
application’s bandwidth requirements. The retransmit mechanism of unicast traffic
provides more reliable transmission of the multicast traffic, although it also produces
duplicate packets.
Select Fixed Multicast Rate to send wireless multicast traffic at a single data rate.
You must know the multicast application’s bandwidth requirements and set it in the
following field.
Multicast Rate
(Mbps) If you set the multicast transmission mode to fixed multicast rate, set the data rate for
multicast traffic here. For example, to deploy 4 Mbps video, select a fixed multicast
rate higher than 4 Mbps.
MBSSID Settings This section allows you to associate an SSID profile with the radio profile.
Edit Select and SSID and click this button to reassign it. The selected SSID becomes
editable immediately upon clicking.

Profile Name Enter up to 31 alphanumeric characters for the profile name. This name is only visible in
the Web Configurator and is only for management purposes. Underscores are allowed.
SSID Enter the SSID name for this profile. This is the name visible on the network to wireless
clients. Enter up to 32 characters, spaces and underscores are allowed.
Security Profile Select a security profile from this list to associate with this SSID. If none exist, you can use
the Create new Obje ct menu to create one.
Note: It is highly recommended that you create security profiles for all of your SSIDs to
enhance your network security.
MAC Filtering
Profile
Select a MAC filtering profile from the list to associate with this SSID. If none exist, you can
use the Create new Ob je ct menu to create one.
MAC filtering allows you to limit the wireless clients connecting to your network through a
particular SSID by wireless client MAC addresses. Any clients that have MAC addresses not
in the MAC filtering profile of allowed addresses are denied connections.
The disable setting means no MAC filtering is used.

QoS Select a Quality of Service (QoS) access category to associate with this SSID. Access
categories minimize the delay of data packets across a wireless network. Certain
categories, such as video or voice, are given a higher priority due to the time sensitive
nature of their data packets.
QoS access categories are as follows:
disable: Turns off QoS for this SSID. All data packets are treated equally and not tagged
with access categories.
WMM: Enables automatic tagging of data packets. The UAG assigns access categories to
the SSID by examining data as it passes through it and making a best guess effort. If
something looks like video traffic, for instance, it is tagged as such.
WMM_VOICE: All wireless traffic to the SSID is tagged as voice data. This is
recommended if an SSID is used for activities like placing and receiving VoIP phone calls.
WMM_VIDEO: All wireless traffic to the SSID is tagged as video data. This is
recommended for activities like video conferencing.
WMM_BEST_EFFORT: All wireless traffic to the SSID is tagged as “best effort,” meaning
the data travels the best route it can without displacing higher priority traffic. This is good
for activities that do not require the best bandwidth throughput, such as surfing the
Internet.
WMM_BACKGROUND: All wireless traffic to the SSID is tagged as low priority or
“background traffic”, meaning all other access categories take precedence over this one. If
traffic from an SSID does not have strict throughput requirements, then this access
category is recommended. For example, an SSID that only has network printers connected
to it.
Rate Limiting
Downlink Define the maximum incoming transmission data rate (either in mbps or kbps) on a per-
station basis.
Uplink Define the maximum outgoing transmission data rate (either in mbps or kbps) on a per-
station basis.
Band Select To improve network performance and avoid interference in the 2.4 GHz frequency band,
you can enable this feature to use the 5 GHz band first. You should set 2.4GHz and 5 GHz
radio profiles to use the same SSID and security settings.
Select standard to have the AP try to connect the wireless clients to the same SSID using
the 5 GHZ band. Connections to an SSID using the 2.4GHz band are still allowed.
Otherwise, select disable to turn off this feature.
VLAN ID Enter the VLAN ID that will be used to tag all traffic originating from this SSID if the VLAN
is different from the native VLAN.
Hidden SSID Select this if you want to “hide” your SSID from wireless clients. This tells any wireless
clients in the vicinity of the AP using this SSID profile not to display its SSID name as a
potential connection. Not all wireless clients respect this flag and display it anyway.
When an SSID is “hidden” and a wireless client cannot see it, the only way you can connect
to the SSID is by manually entering the SSID name in your wireless connection setup
screen(s) (these vary by client, client connectivity software, and operating system).
Enable Intra-BSS
Traffic Blocking
Select this option to prevent crossover traffic from within the same SSID.
Local VAP
Setting
This section is available only on the UAG that supports a local AP.
VLAN Support Select ON to tag traffic from the local Virtual AP (VAP) with the VLAN ID specified in this
SSID profile. Otherwise, select Off.

37.3 Technical Reference
The following section contains additional technical information about the features described in this
chapter.
Rogue APs
Rogue APs are wireless access points operating in a network’s coverage area that are not under the
control of the network’s administrators, and can open up holes in a network’s security. Attackers
can take advantage of a rogue AP’s weaker (or non-existent) security to gain access to the network,
or set up their own rogue APs in order to capture information from wireless clients. If a scan reveals
a rogue AP, you can use commercially-available software to physically locate it.
Figure 290 Rogue AP Example
In the example above, a corporate network’s security is compromised by a rogue AP (RG) set up by
an employee at his workstation in order to allow him to connect his notebook computer wirelessly
(A). The company’s legitimate wireless network (the dashed ellipse B) is well-secured, but the
rogue AP uses inferior security that is easily broken by an attacker (X) running readily available
encryption-cracking software. In this example, the attacker now has access to the company
network, including sensitive data stored on the file server (C).
Set Scan Channel
List (5 GHz)
Move a channel from the Available channels column to the Channels selected
column to have the APs using this profile scan that channel when Scan Channel Mode
is set to manual.
These channels are limited to the 5 GHz range (802.11 a/n).

Friendly APs
If you have more than one AP in your wireless network, you should also configure a list of “friendly”
APs. Friendly APs are other wireless access points that are detected in your network, as well as any
others that you know are not a threat (those from recognized networks, for example). It is
recommended that you export (save) your list of friendly APs often, especially if you have a
network with a large number of access points.

CHAPTER 40
Services
40.1 Overview
Use service objects to define TCP applications, UDP applications, and ICMP messages. You can also
create service groups to refer to multiple service objects in other features.
40.1.1 What You Can Do in this Chapter
•Use the Service screens (Section 40.2 on page 448) to view and configure the UAG’s list of
services and their definitions.
•Use the Service Group screens (Section 40.2 on page 448) to view and configure the UAG’s list
of service groups.
40.1.2 What You Need to Know
IP Protoc ols
IP protocols are based on the eight-bit protocol field in the IP header. This field represents the next-
level protocol that is sent in this packet. This section discusses three of the most common IP
protocols.
Computers use Transmission Control Protocol (TCP, IP protocol 6) and User Datagram Protocol
(UDP, IP protocol 17) to exchange data with each other. TCP guarantees reliable delivery but is
slower and more complex. Some uses are FTP, HTTP, SMTP, and TELNET. UDP is simpler and faster
but is less reliable. Some uses are DHCP, DNS, RIP, and SNMP.
TCP creates connections between computers to exchange data. Once the connection is established,
the computers exchange data. If data arrives out of sequence or is missing, TCP puts it in sequence
or waits for the data to be re-transmitted. Then, the connection is terminated.
In contrast, computers use UDP to send short messages to each other. There is no guarantee that
the messages arrive in sequence or that the messages arrive at all.
Both TCP and UDP use ports to identify the source and destination. Each port is a 16-bit number.
Some port numbers have been standardized and are used by low-level system processes; many
others have no particular meaning.
Unlike TCP and UDP, Internet Control Message Protocol (ICMP, IP protocol 1) is mainly used to send
error messages or to investigate problems. For example, ICMP is used to send the response if a
computer cannot be reached. Another use is ping. ICMP does not guarantee delivery, but networks
often treat ICMP messages differently, sometimes looking at the message itself to decide where to
send it.
Chapter 40 Services
UAG Series User’s Guide
448
Service Objects and Service Groups
Use service objects to define IP protocols.
• TCP applications
• UDP applications
• ICMP messages
• user-defined services (for other types of IP protocols)
These objects are used in policy routes, and security policies.
Use service groups when you want to create the same rule for several services, instead of creating
separate rules for each service. Service groups may consist of services and other service groups.
The sequence of members in the service group is not important.
40.2 The Service Summary Screen
The Service summary screen provides a summary of all services and their definitions. In addition,
this screen allows you to add, edit, and remove services.
To access this screen, log in to the Web Configurator, and click Configuration > Object > Service

CHAPTER 41
Schedules
41.1 Overview
Use schedules to set up one-time and recurring schedules for policy routes, and security policies.
The UAG supports one-time and recurring schedules. One-time schedules are effective only once,
while recurring schedules usually repeat. Both types of schedules are based on the current date and
time in the UAG.
Note: Schedules are based on the UAG’s current date and time.
41.1.1 What You Can Do in this Chapter
•Use the Schedule summary screen (Section 41.2 on page 454) to see a list of all schedules in
the UAG.
•Use the One-Time Schedule Add/Edit screen (Section 41.2.1 on page 455) to create or edit a
one-time schedule.
•Use the Recurring Schedule Add/Edit screen (Section 41.2.2 on page 456) to create or edit a
recurring schedule.
•Use the Schedule Group screen (Section 41.3 on page 457) to merge individual schedule
objects as one object.
41.1.2 What You Need to Know
One-time Schedules
One-time schedules begin on a specific start date and time and end on a specific stop date and
time. One-time schedules are useful for long holidays and vacation periods.
Recurring Schedules
Recurring schedules begin at a specific start time and end at a specific stop time on selected days of
the week (Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday). Recurring
schedules always begin and end in the same day. Recurring schedules are useful for defining the
workday and off-work hours.

CHAPTER 42
AAA Server
42.1 Overview
You can use a AAA (Authentication, Authorization, Accounting) server to provide access control to
your network. The AAA server can be a RADIUS server. Use the AAA Server screens to create and
manage objects that contain settings for using AAA servers. You use AAA server objects in
configuring ext-group-user user objects and authentication method objects (see Chapter 43 on
page 464).
42.1.1 RADIUS Server
RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used to
authenticate users by means of an external server instead of (or in addition to) an internal device
user database that is limited to the memory capacity of the device. In essence, RADIUS
authentication allows you to validate a large number of users from a central location.
Figure 311 RADIUS Server Network Example
42.1.2 What You Can Do in this Chapter
Use the Configuration > Object > AAA Server > RADIUS screen (Section 42.2 on page 460) to
configure the default external RADIUS server to use for user authentication.
42.1.3 What You Need To Know
AAA Servers Supported by the UAG
The following lists the types of authentication server the UAG supports.
•Local user database
The UAG uses the built-in local user database to authenticate administrative users logging into
the UAG’s Web Configurator or network access users logging into the network through the UAG.
Chapter 42 AAA Server
UAG Series User’s Guide

•RADIUS
RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used
to authenticate users by means of an external or built-in RADIUS server. RADIUS authentication
allows you to validate a large number of users from a central location.

belongs. You can add ext-group-user user objects to identify groups based on these
group identifier values.
For example you could have an attribute named “memberOf” with values like “sales”,
“RD”, and “management”. Then you could also create a ext-group-user user object for
each group. One with “sales” as the group identifier, another for “RD” and a third for
“management”.

Authentication Method
43.1 Overview
Authentication method objects set how the UAG authenticates wireless, HTTP/HTTPS clients, and
peer IPSec routers (extended authentication) clients. Configure authentication method objects to
have the UAG use the local user database, and/or the authentication servers and authentication
server groups specified by AAA server objects. By default, user accounts created and stored on the
UAG are authenticated locally.
43.1.1 What You Can Do in this Chapter
•Use the Configuration > Object > Auth. Method screens (Section 43.2 on page 464) to create
and manage authentication method objects.
43.1.2 Before You Begin
Configure AAA server objects (see Chapter 42 on page 459) before you configure authentication
method objects.
43.2 Authentication Method Objects
Click Configuration > Object > Auth. Method to display the screen as shown.

CHAPTER 44
Certificates
44.1 Overview
The UAG can use certificates (also called digital IDs) to authenticate users. Certificates are based
on public-private key pairs. A certificate contains the certificate owner’s identity and public key.
Certificates provide a way to exchange public keys for use in authentication.
44.1.1 What You Can Do in this Chapter
•Use the My Certificates screens (see Section 44.2 on page 470 to Section 44.2.3 on page 476)
to generate and export self-signed certificates or certification requests and import the CA-signed
certificates.
•Use the Trusted Certificates screens (see Section 44.3 on page 477 to Section 44.3.2 on page
481) to save CA certificates and trusted remote host certificates to the UAG. The UAG trusts any
valid certificate that you have imported as a trusted certificate. It also trusts any valid certificate
signed by any of the certificates that you have imported as a trusted certificate.
44.1.2 What You Need to Know
When using public-key cryptology for authentication, each host has two keys. One key is public and
can be made openly available. The other key is private and must be kept secure.
These keys work like a handwritten signature (in fact, certificates are often referred to as “digital
signatures”). Only you can write your signature exactly as it should look. When people know what
your signature looks like, they can verify whether something was signed by you, or by someone
else. In the same way, your private key “writes” your digital signature and your public key allows
people to verify whether data was signed by you, or by someone else. This process works as
follows.
1Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that
the message content has not been altered by anyone else along the way. Tim generates a public
key pair (one public key and one private key).
2Tim keeps the private key and makes the public key openly available. This means that anyone who
receives a message seeming to come from Tim can read it and verify whether it is really from him
or not.
3Tim uses his private key to sign the message and sends it to Jenny.
4Jenny receives the message and uses Tim’s public key to verify it. Jenny knows that the message is
from Tim, and that although other people may have been able to read the message, no-one can
have altered it (because they cannot re-sign the message with Tim’s private key).
Chapter 44 Certificates
UAG Series User’s Guide
468
5Additionally, Jenny uses her own private key to sign a message and Tim uses Jenny’s public key to
verify the message.
The UAG uses certificates based on public-key cryptology to authenticate users attempting to
establish a connection, not to encrypt the data that you send after establishing a connection. The
method used to secure the data that you send through an established connection depends on the
type of connection.
The certification authority uses its private key to sign certificates. Anyone can then use the
certification authority’s public key to verify the certificates.
A certification path is the hierarchy of certification authority certificates that validate a certificate.
The UAG does not trust a certificate if any certificate on its path has expired or been revoked.
Certification authorities maintain directory servers with databases of valid and revoked certificates.
A directory of certificates that have been revoked before the scheduled expiration is called a CRL
(Certificate Revocation List). The UAG can check a peer’s certificate against a directory server’s list
of revoked certificates. The framework of servers, software, procedures and policies that handles
keys is called PKI (public-key infrastructure).
Advantages of Certificates
Certificates offer the following benefits.
• The UAG only has to store the certificates of the certification authorities that you decide to trust,
no matter how many devices you need to authenticate.
• Key distribution is simple and very secure since you can freely distribute public keys and you
never need to transmit private keys.
Self-signed Certificates
You can have the UAG act as a certification authority and sign its own certificates.
Factory Default Certificate
The UAG generates its own unique self-signed certificate when you first turn it on. This certificate is
referred to in the GUI as the factory default certificate.
Certificate File Formats
Any certificate that you want to import has to be in one of these file formats:
• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters,
uppercase letters and numerals to convert a binary X.509 certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital
signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The
private key is not included. The UAG currently allows the importation of a PKS#7 file that
contains a single certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase
letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable
form.
Chapter 44 Certificates
UAG Series User’s Guide
469
• Binary PKCS#12: This is a format for transferring public key and private key certificates. The
private key in a PKCS #12 file is within a password-encrypted envelope. The file’s password is not
connected to your certificate’s public or private passwords. Exporting a PKCS #12 file creates this
and you must provide it to decrypt the contents when you import the file into the UAG.
Note: Be careful not to convert a binary file to text during the transfer process. It is easy
for this to occur since many programs use text files by default.
44.1.3 Verifying a Certificate
Before you import a trusted certificate into the UAG, you should verify that you have the correct
certificate. You can do this using the certificate’s fingerprint. A certificate’s fingerprint is a message
digest calculated using the MD5 or SHA1 algorithm. The following procedure describes how to check
a certificate’s fingerprint to verify that you have the actual certificate.
1Browse to where you have the certificate saved on your computer.
2Make sure that the certificate has a “.cer” or “.crt” file name extension.
Figure 316 Remote Host Certificates
3Double-click the certificate’s icon to open the Certificate window. Click the Details tab and scroll
down to the Thumbprint Algorithm and Thumbprint fields.
Figure 317 Certificate Details
Chapter 44 Certificates
UAG Series User’s Guide
470
4Use a secure method to verify that the certificate owner has the same information in the
Thumbprint Algorithm and Thumbprint fields. The secure method may very based on your
situation. Possible examples would be over the telephone or through an HTTPS connection.

46.4.1 Pre-defined NTP Time Servers List
When you turn on the UAG for the first time, the date and time start at 2003-01-01 00:00:00. The
UAG then attempts to synchronize with one of the following pre-defined list of Network Time
Protocol (NTP) time servers.
The UAG continues to use the following pre-defined list of NTP time servers if you do not specify a
time server or it cannot synchronize with the time server you specified.
When the UAG uses the pre-defined list of NTP time servers, it randomly selects one server and
tries to synchronize with it. If the synchronization fails, then the UAG goes through the rest of the
list in order from the first one tried until either it is successful or all the pre-defined NTP time
servers have been tried.

46.6 DNS Overview
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and
vice versa. The DNS server is extremely important because without it, you must know the IP
address of a machine before you can access it.
46.6.1 DNS Server Address Assignment
The UAG can get the DNS server addresses in the following ways.
• The ISP tells you the DNS server addresses, usually in the form of an information sheet, when
you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server
fields.
• If your ISP dynamically assigns the DNS server IP addresses (along with the UAG’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
• You can manually enter the IP addresses of other DNS servers.
46.6.2 Configuring the DNS Screen
Click Configuration > System > DNS to change your UAG’s DNS settings. Use the DNS screen to
configure the UAG to use a DNS server to resolve domain names for UAG system features like
DDNS and the time server. You can also configure the UAG to accept or discard DNS queries. Use
the Network > Interface screens to configure the DNS server information that the UAG sends to
the specified DHCP client devices.

46.6.3 Address Record
An address record contains the mapping of a Fully-Qualified Domain Name (FQDN) to an IP
address. An FQDN consists of a host and domain name. For example, www.zyxel.com is a fully
qualified domain name, where “www” is the host, “zyxel” is the second-level domain, and “com” is
the top level domain. mail.myZyXEL.com.tw is also a FQDN, where “mail” is the host, “myZyXEL” is
the third-level domain, “com” is the second-level domain, and “tw” is the top level domain.
The UAG allows you to configure address records about the UAG itself or another device. This way
you can keep a record of DNS names and addresses that people on your network may use
frequently. If the UAG receives a DNS query for an FQDN for which the UAG has an address record,
the UAG can send the IP address in a DNS response without having to query a DNS name server.

The following table describes the labels in this screen.
46.6.6 CNAME Record
A Canonical Name Record or CNAME record is a type of resource record in the Domain Name
System (DNS) that specifies that the domain name is an alias of another, canonical domain name.
This allows users to set up a record for a domain name which translates to an IP address, in other
words, the domain name is an alias of another. This record also binds all the subdomains to the
same IP address without having to create a record for each, so when the IP address is changed, all
subdomain’s IP address is updated as well, with one edit to the record.
For example, the domain name zyxel.com is hooked up to a record named A which translates it to
11.22.33.44. You also have several subdomains, like mail.zyxel.com, ftp.zyxel.com and you want
this subdomain to point to your main domain zyxel.com. Edit the IP address in record A and all
subdomains will follow automatically. This eliminates chances for errors and increases efficiency in
DNS management.
46.6.7 Adding a CNAME Record
Click the Add icon in the CNAME Record table to add a record. Use “*.” as a prefix for a wildcard
domain name. For example *.zyxel.com.

A MX (Mail eXchange) record indicates which host is responsible for the mail for a particular
domain, that is, controls where mail is sent for that domain. If you do not configure proper MX
records for your domain or other domain, external e-mail from other mail servers will not be able to
be delivered to your mail server and vice versa. Each host or domain can have only one MX record,
that is, one domain is mapping to one host.

46.7 WWW Overview
The following figure shows secure and insecure management of the UAG coming in from the WAN.
HTTPS and SSH access are secure. HTTP and Telnet access are not secure.
Note: To allow the UAG to be accessed from a specified computer using a service, make
sure you do not have a service control rule or to-Device security policy to block
that traffic.
•See To-Device Rules on page 290 for more on To-Device security policies.
To stop a service from accessing the UAG, clear Enable in the corresponding service screen.
46.7.1 Service Access Limitations
A service cannot be used to access the UAG when:
1You have disabled that service in the corresponding screen.
2The allowed IP address (address object) in the Service Control table does not match the client IP
address (the UAG disallows the session).
3The IP address (address object) in the Service Control table is not in the allowed zone or the
action is set to Deny.
4There is a security policy that blocks it.
46.7.2 System Timeout
There is a lease timeout for administrators. The UAG automatically logs you out if the management
session remains idle for longer than this timeout period. The management session does not time
out when a statistics screen is polling.
Each user is also forced to log in the UAG for authentication again when the reauthentication time
expires.
You can change the timeout settings in the User/Group screens.
Action Select Accept to have the UAG allow the DNS queries from the specified computer.
Select Deny to have the UAG reject the DNS queries from the specified computer.

46.7.3 HTTPS
You can set the UAG to use HTTP or HTTPS (HTTPS adds security) for Web Configurator sessions.
Specify which zones allow Web Configurator access and from which IP address the access can
come.
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol
that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level protocol
that enables secure transactions of data by ensuring confidentiality (an unauthorized party cannot
read the transferred data), authentication (one party can identify the other party) and data
integrity (you know if data has been changed).
It relies upon certificates, public keys, and private keys (see Chapter 44 on page 467 for more
information).
HTTPS on the UAG is used so that you can securely access the UAG using the Web Configurator. The
SSL protocol specifies that the HTTPS server (the UAG) must always authenticate itself to the
HTTPS client (the computer which requests the HTTPS connection with the UAG), whereas the
HTTPS client only should authenticate itself when the HTTPS server requires it to do so (select
Authenticate Client Certificates in the WWW screen). Authenticate Client Certificates is
optional and if selected means the HTTPS client must send the UAG a certificate. You must apply for
a certificate for the browser from a CA that is a trusted CA on the UAG.
Please refer to the following figure.
1HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the
UAG’s web server.
2HTTP connection requests from a web browser go to port 80 (by default) on the UAG’s web server.
Figure 338 HTTP/HTTPS Implementation
Note: If you disable HTTP in the WWW screen, then the UAG blocks all HTTP connection
attempts.
46.7.4 Configuring WWW Service Control
Click Configuration > System > WWW to open the WWW screen. Use this screen to specify
from which zones you can access the UAG using HTTP or HTTPS. You can also specify which IP
addresses the access can come from.

Here are the main reasons your browser displays warnings about the UAG’s HTTPS server certificate
and what you can do to avoid seeing the warnings:
• The issuing certificate authority of the UAG’s HTTPS server certificate is not one of the browser’s
trusted certificate authorities. The issuing certificate authority of the UAG's factory default
certificate is the UAG itself since the certificate is a self-signed certificate.
• For the browser to trust a self-signed certificate, import the self-signed certificate into your
operating system as a trusted certificate.
• To have the browser trust the certificates issued by a certificate authority, import the certificate
authority’s certificate into your operating system as a trusted certificate.

46.8 SSH
You can use SSH (Secure SHell) to securely access the UAG’s command line interface. Specify
which zones allow SSH access and from which IP address the access can come.
SSH is a secure communication protocol that combines authentication and data encryption to
provide secure encrypted communication between two hosts over an unsecured network. In the
following figure, computer A on the Internet uses SSH to securely connect to the WAN port of the
UAG for a management session.
Chapter 46 System
UAG Series User’s Guide
519
Figure 360 SSH Communication Over the WAN Example
46.8.1 How SSH Works
The following figure is an example of how a secure connection is established between two remote
hosts using SSH v1.
Figure 361 How SSH v1 Works Example
1Host Identification
The SSH client sends a connection request to the SSH server. The server identifies itself with a host
key. The client encrypts a randomly generated session key with the host key and server key and
sends the result back to the server.
The client automatically saves any new server public keys. In subsequent connections, the server
public key is checked against the saved version on the client computer.
2Encryption Method
Once the identification is verified, both the client and server must agree on the type of encryption
method to use.
A
Chapter 46 System
UAG Series User’s Guide
520
3Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is established
between the client and the server. The client then sends its authentication information (user name
and password) to the server to log in to the server.
46.8.2 SSH Implementation on the UAG
Your UAG supports SSH versions 1 and 2 using RSA authentication and four encryption methods
(AES, 3DES, Archfour, and Blowfish). The SSH server is implemented on the UAG for management
using port 22 (by default).
46.8.3 Requirements for Using SSH
You must install an SSH client program on a client computer (Windows or Linux operating system)
that is used to connect to the UAG over SSH.
46.8.4 Configuring SSH

Figure 368 SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the UAG). An agent
translates the local management information from the managed device into a form compatible with
SNMP. The manager is the console through which network administrators perform network
management functions. It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of
packets received, node port status etc. A Management Information Base (MIB) is a collection of
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an
agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it
initiates a Get operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.
46.11.1 Supported MIBs
The UAG supports MIB II that is defined in RFC-1213 and RFC-1215. The UAG also supports private
MIBs (private.mib and enterprise.mib) to collect information about CPU and memory usage. The
focus of the MIBs is to let administrators collect statistical data and monitor status and
performance. You can download the UAG’s MIBs from www.zyxel.com.

CHAPTER 48
File Manager
48.1 Overview
Configuration files define the UAG’s settings. Shell scripts are files of commands that you can store
on the UAG and run when you need them. You can apply a configuration file or run a shell script
without the UAG restarting. You can store multiple configuration files and shell script files on the
UAG. You can edit configuration files or shell scripts in a text editor and upload them to the UAG.
Configuration files use a .conf extension and shell scripts use a .zysh extension.
48.1.1 What You Can Do in this Chapter
•Use the Configuration File screen (see Section 48.2 on page 551) to store and name
configuration files. You can also download configuration files from the UAG to your computer and
upload configuration files from your computer to the UAG.
•Use the Firmware Package screen (see Section 48.3 on page 555) to check your current
firmware version and upload firmware to the UAG.
•Use the Shell Script screen (see Section 48.4 on page 557) to store, name, download, upload
and run shell script files.
48.1.2 What you Need to Know
Configuration Files and Shell Scripts
When you apply a configuration file, the UAG uses the factory default settings for any features that
the configuration file does not include. When you run a shell script, the UAG only applies the
commands that it contains. Other settings do not change.
Chapter 48 File Manager
UAG Series User’s Guide
550
These files have the same syntax, which is also identical to the way you run CLI commands
manually. An example is shown below.
While configuration files and shell scripts have the same syntax, the UAG applies configuration files
differently than it runs shell scripts. This is explained below.
You have to run the example in Figure 381 on page 550 as a shell script because the first command
is run in Privilege mode. If you remove the first command, you have to run the example as a
configuration file because the rest of the commands are executed in Configuration mode.
Comments in Configuration Files or Shell Scripts
In a configuration file or shell script, use “#” or “!” as the first character of a command line to have
the UAG treat the line as a comment.
Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!” to
have the UAG exit sub command mode.
Note: “exit” or “!'” must follow sub commands if it is to make the UAG exit sub command
mode.
Figure 381 Configuration File / Shell Script: Example
# enter configuration mode

# change administrator password

# configure wan1

Line 3 in the following example exits sub command mode.
Lines 1 and 3 in the following example are comments and line 4 exits sub command mode.
Lines 1 and 2 are comments. Line 5 exits sub command mode.
Errors in Configuration Files or Shell Scripts
When you apply a configuration file or run a shell script, the UAG processes the file line-by-line. The
UAG checks the first line and applies the line if no errors are detected. Then it continues with the
next line. If the UAG finds an error, it stops applying the configuration file or shell script and
generates a log.
You can change the way a configuration file or shell script is applied. Include setenv stop-on-
error off in the configuration file or shell script. The UAG ignores any errors in the configuration
file or shell script and applies all of the valid commands. The UAG still generates a log for any
errors.
48.2 The Configuration File Screen
Click Maintenance > File Manager > Configuration File to open the Configuration File
screen. Use the Configuration File screen to store, run, and name configuration files. You can also
download configuration files from the UAG to your computer and upload configuration files from
your computer to the UAG.
Once your UAG is configured and functioning properly, it is highly recommended that you back up
your configuration file before making further configuration changes. The backup configuration file
will be useful in case you need to return to your previous settings.

Configuration File Flow at Restart
• If there is not a startup-config.conf when you restart the UAG (whether through a
management interface or by physically turning the power off and back on), the UAG uses the
system-default.conf configuration file with the UAG’s default settings.
•If there is a startup-config.conf, the UAG checks it for errors and applies it. If there are no
errors, the UAG uses it and copies it to the lastgood.conf configuration file as a back up file. If
there is an error, the UAG generates a log and copies the startup-config.conf configuration file
to the startup-config-bad.conf configuration file and tries the existing lastgood.conf
configuration file. If there isn’t a lastgood.conf configuration file or it also has an error, the UAG
applies the system-default.conf configuration file.
• You can change the way the startup-config.conf file is applied. Include the setenv-startup
stop-on-error off command. The UAG ignores any errors in the startup-config.conf file and
applies all of the valid commands. The UAG still generates a log for any errors.

Immediately stop applying the configuration file - this is not recommended because
it would leave the rest of the configuration blank. If the interfaces were not configured
before the first error, the console port may be the only way to access the device.
Immediately stop applying the configuration file and roll back to the previous
configuration - this gets the UAG started with a fully valid configuration file as quickly as
possible.
Ignore errors and finish applying the configuration file - this applies the valid parts
of the configuration file and generates error logs for all of the configuration file’s errors.
This lets the UAG apply most of your configuration and you can refer to the logs for what to
fix.

Note: The UAG reserves some onboard storage space as a buffer.
Save data to USB
storage
Select this to have the UAG store packet capture entries only on a USB storage
device connected to the UAG.
Status:
Unused - the connected USB storage device was manually unmounted by using the
Remove Now button or for some reason the UAG cannot mount it.
none - no USB storage device is connected.
available - you can have the UAG use the USB storage device. The available
storage capacity also displays.
service deactivated - the USB storage feature is disabled and the UAG cannot use
a connected USB device to store the system log and other diagnostic information.
Note: The UAG reserves some USB storage space as a buffer.
Captured Packet Files When saving packet captures only to the UAG’s onboard storage, specify a
maximum limit in megabytes for the total combined size of all the capture files on
the UAG.
When saving packet captures to a connected USB storage device, specify a
maximum limit in megabytes for each capture file.
Note: If you have existing capture files and have not selected the Continuously
capture and overwrite old ones option, you may need to set this size larger or
delete existing capture files.
The valid range depends on the available onboard/USB storage size. The UAG stops
the capture and generates the capture file when either the file reaches this size or
the time period specified in the Duration field expires.
Split threshold Specify a maximum size limit in megabytes for individual packet capture files. After
a packet capture file reaches this size, the UAG starts another packet capture file.
Duration Set a time limit in seconds for the capture. The UAG stops the capture and
generates the capture file when either this period of time has passed or the file
reaches the size specified in the File Size field. 0 means there is no time limit.
File Suffix Specify text to add to the end of the file name (before the dot and filename
extension) to help you identify the packet capture files. Modifying the file suffix also
avoids making new capture files that overwrite existing files of the same name.
The file name format is “interface name-file suffix.cap”, for example “vlan2-packet-
capture.cap”.
Number Of Bytes To
Capture (Per Packet)
Specify the maximum number of bytes to capture per packet. The UAG
automatically truncates packets that exceed this size. As a result, when you view
the packet capture files in a packet analyzer, the actual size of the packets may be
larger than the size of captured packets.

CHAPTER 51
Reboot
51.1 Overview
Use this to restart the device (for example, if the device begins behaving erratically). See also
Section 1.5 on page 35 for information on different ways to start and stop the UAG.
51.1.1 What You Need To Know
If you applied changes in the Web configurator, these were saved automatically and do not change
when you reboot. If you made changes in the CLI, however, you have to use the write command to
save the configuration before you reboot. Otherwise, the changes are lost when you reboot.
Reboot is different to reset; (see Section 53.1 on page 589) reset returns the device to its default
configuration.
51.2 The Reboot Screen
The Reboot screen allows remote users to restart the device. To access this screen, click
Maintenance > Reboot.
Figure 416 Maintenance > Reboot
Click the Reboot button to restart the UAG. Wait a few minutes until the login screen appears. If

CHAPTER 53
Troubleshooting
This chapter offers some suggestions to solve problems you might encounter.
• You can also refer to the logs (see Chapter 7 on page 125).
• For the order in which the UAG applies its features and checks, see Chapter 50 on page 572.
None of the LEDs turn on.
Make sure that you have the power cord connected to the UAG and plugged in to an appropriate
power source. Make sure you have the UAG turned on. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you should contact
your local vendor.
Cannot access the UAG from the LAN.
• Check the cable connection between the UAG and your computer or switch.
• Ping the UAG from a LAN computer. Make sure your computer’s Ethernet card is installed and
functioning properly. Also make sure that its IP address is in the same subnet as the UAG’s.
• In the computer, click Start, (All) Programs, Accessories and then Command Prompt. In
the Command Prompt window, type "ping" followed by the UAG’s LAN IP address (172.16.0.1
or 172.17.0.1 is the default) and then press [ENTER]. The UAG should reply.
• If you’ve forgotten the UAG’s password, use the RESET button. Press the button in for about 5
seconds (or until the PWR LED starts to blink), then release it. It returns the UAG to the factory
defaults (password is 1234, LAN IP address 172.16.0.1 or 172.17.0.1 etc.; see your User’s Guide
for details).
• If you’ve forgotten the UAG’s IP address, you can use the commands through the console port to
check it. Connect your computer to the CONSOLE port using a console cable. Your computer
should have a terminal emulation communications program (such as HyperTerminal) set to
VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow control and 115200 bps port
speed.
I cannot access the Internet.
• Check the UAG’s connection to the Ethernet jack with Internet access. Make sure the Internet
gateway device (such as a DSL modem) is working properly.
Chapter 53 Troubleshooting
UAG Series User’s Guide
584
• Check the WAN interface's status in the Dashboard. Use the installation setup wizard again and
make sure that you enter the correct settings. Use the same case as provided by your ISP.
I configured security settings but the UAG is not applying them for certain interfaces.
Many security settings are usually applied to zones. Make sure you assign the interfaces to the
appropriate zones. When you create an interface, there is no security applied on it until you assign
it to a zone.
The UAG is not applying the custom policy route I configured.
The UAG checks the policy routes in the order that they are listed. So make sure that your custom
policy route comes before any other routes that the traffic would also match.
The UAG is not applying the custom security policy I configured.
The UAG checks the security policies in the order that they are listed. So make sure that your
custom security policy comes before any other rules that the traffic would also match.
I cannot enter the interface name I want.
• The format of interface names other than the Ethernet interface names is very strict. Each name
consists of 2-4 letters (interface type), followed by a number (x, limited by the maximum
number of each type of interface). For example, VLAN interfaces are vlan0, vlan1, vlan2, ...; and
so on.
• The names of virtual interfaces are derived from the interfaces on which they are created. For
example, virtual interfaces created on Ethernet interface wan1 are called wan1:1, wan1:2, and
so on. Virtual interfaces created on VLAN interface vlan2 are called vlan2:1, vlan2:2, and so on.
You cannot specify the number after the colon(:) in the Web Configurator; it is a sequential
number. You can specify the number after the colon if you use the CLI to set up a virtual
interface.
I cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface on an
Ethernet interface.
You cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface if the
underlying interface is a member of a bridge. You also cannot add an Ethernet interface or VLAN
interface to a bridge if the member interface has a virtual interface or PPP interface on top of it.
Chapter 53 Troubleshooting
UAG Series User’s Guide
585
My rules and settings that apply to a particular interface no longer work.
The interface’s IP address may have changed. To avoid this create an IP address object based on
the interface. This way the UAG automatically updates every rule or setting that uses the object
whenever the interface’s IP address settings change. For example, if you change LAN1’s IP address,
the UAG automatically updates the corresponding interface-based, LAN1 subnet address object.
I cannot set up a PPP interface.
You have to set up an ISP account before you create a PPPoE or PPTP interface.
I cannot configure a particular VLAN interface on top of an Ethernet interface even though I
have it configured it on top of another Ethernet interface.
Each VLAN interface is created on top of only one Ethernet interface.
The UAG is not applying an interface’s configured ingress bandwidth limit.
At the time of writing, the UAG does not support ingress bandwidth management.
The UAG routes and applies SNAT for traffic from some interfaces but not from others.
The UAG automatically uses SNAT for traffic it routes from internal interfaces to external interfaces.
For example LAN to WAN traffic. You must manually configure a policy route to add routing and
SNAT settings for an interface with the Interface Type set to General. You can also configure a
policy route to override the default routing and SNAT behavior for an interface with the Interface
Type set to Internal or External.
I cannot get Dynamic DNS to work.
• You must have a public WAN IP address to use Dynamic DNS.
• Make sure you recorded your DDNS account’s user name, password, and domain name and have
entered them properly in the UAG.
• You may need to configure the DDNS entry’s IP Address setting to Auto if the interface has a
dynamic IP address or there are one or more NAT routers between the UAG and the DDNS server.
Chapter 53 Troubleshooting
UAG Series User’s Guide
586
• The UAG may not determine the proper IP address if there is an HTTP proxy server between the
UAG and the DDNS server.
I cannot create a second HTTP redirect rule for an incoming interface.
You can configure up to one HTTP redirect rule for each (incoming) interface.
The UAG keeps resetting the connection.
If an alternate gateway on the LAN has an IP address in the same subnet as the UAG’s LAN IP
address, return traffic may not go through the UAG. This is called an asymmetrical or “triangle”
route. This causes the UAG to reset the connection, as the connection has not been acknowledged.
You can set the UAG’s security policies to permit the use of asymmetrical route topology on the
network (so it does not reset the connection) although this is not recommended since allowing
asymmetrical routes may let traffic from the WAN go directly to the LAN without passing through
the UAG. A better solution is to use virtual interfaces to put the UAG and the backup gateway on
separate subnets. See Asymmetrical Routes on page 291 and the chapter about interfaces for more
information.
I changed the LAN IP address and can no longer access the Internet.
The UAG automatically updates address objects based on an interface’s IP address, subnet, or
gateway if the interface’s IP address settings change. However, you need to manually edit any
address objects for your LAN that are not based on the interface.
I cannot get the RADIUS server to authenticate the UAG‘s default admin account.
The default admin account is always authenticated locally, regardless of the authentication method
setting. (See Chapter 42 on page 459 for more information about authentication methods.)
The UAG fails to authentication the ext-user user accounts I configured.
An external server such as RADIUS must authenticate the ext-user accounts. If the UAG tries to use
the local database to authenticate an ext-user, the authentication attempt will always fail. (This is
related to AAA servers and authentication methods, which are discussed in Chapter 42 on page 459
and Chapter 43 on page 464, respectively.)

I cannot add the admin users to a user group with access users.
You cannot put access users and admin users in the same user group.
I cannot add the default admin account to a user group.
You cannot put the default admin account into any user group.
The schedule I configured is not being applied at the configured times.
Make sure the UAG’s current date and time are correct.
I cannot get a certificate to import into the UAG.
1For My Certificates, you can import a certificate that matches a corresponding certification
request that was generated by the UAG. You can also import a certificate in PKCS#12 format,
including the certificate’s public and private keys.
2You must remove any spaces from the certificate’s filename before you can import the certificate.
3Any certificate that you want to import has to be in one of these file formats:
• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters,
uppercase letters and numerals to convert a binary X.509 certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital
signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The
private key is not included. The UAG currently allows the importation of a PKS#7 file that
contains a single certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase
letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable
form.
• Binary PKCS#12: This is a format for transferring public key and private key certificates.The
private key in a PKCS #12 file is within a password-encrypted envelope. The file’s password is not
connected to your certificate’s public or private passwords. Exporting a PKCS #12 file creates this
and you must provide it to decrypt the contents when you import the file into the UAG.
Note: Be careful not to convert a binary file to text during the transfer process. It is easy
for this to occur since many programs use text files by default.

I cannot access the UAG from a computer connected to the Internet.
Check the service control rules and to-UAG security policies.
I uploaded a logo to display on the upper left corner of the Web Configurator login screen and
access page but it does not display properly.
Make sure the logo file is a GIF, JPG, or PNG of 100 kilobytes or less.
I uploaded a logo to use as the screen or window background but it does not display properly.
Make sure the logo file is a GIF, JPG, or PNG of 100 kilobytes or less.
The UAG’s traffic throughput rate decreased after I started collecting traffic statistics.
Data collection may decrease the UAG’s traffic throughput rate.
I can only see newer logs. Older logs are missing.
When a log reaches the maximum number of log messages, new log messages automatically
overwrite existing log messages, starting with the oldest existing log message first.
The commands in my configuration file or shell script are not working properly.
• In a configuration file or shell script, use “#” or “!” as the first character of a command line to
have the UAG treat the line as a comment.
• Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!”
to have the UAG exit sub command mode.
•Include write commands in your scripts. Otherwise the changes will be lost when the UAG
restarts. You could use multiple write commands in a long script.
Note: “exit” or “!'” must follow sub commands if it is to make the UAG exit sub command
mode.
See Chapter 48 on page 549 for more on configuration files and shell scripts.
Chapter 53 Troubleshooting
UAG Series User’s Guide
589
I cannot get the firmware uploaded using the commands.
The Web Configurator is the recommended method for uploading firmware. You only need to use
the command line interface if you need to recover the firmware. See the CLI Reference Guide for
how to determine if you need to recover the firmware and how to recover it.
My packet capture captured less than I wanted or failed.
The packet capture screen’s File Size sets a maximum size limit for the total combined size of all
the capture files on the UAG, including any existing capture files and any new capture files you
generate. If you have existing capture files you may need to set this size larger or delete existing
capture files.
The UAG stops the capture and generates the capture file when either the capture files reach the
File Size or the time period specified in the Duration field expires.
My earlier packet capture files are missing.
New capture files overwrite existing files of the same name. Change the File Suffix field’s setting
to avoid this.
53.1 Resetting the UAG
If you cannot access the UAG by any method, try restarting it by turning the power off and then on
again. If you still cannot access the UAG by any method or you forget the administrator
password(s), you can reset the UAG to its factory-default settings. Any configuration files or shell
scripts that you saved on the UAG should still be available afterwards.
Use the following procedure to reset the UAG to its factory-default settings. This overwrites the
settings in the startup-config.conf file with the settings in the system-default.conf file.
Note: This procedure removes the current configuration.
If you want to reboot the device without changing the current configuration, see Chapter 51 on
page 581.
1Make sure the SYS LED is on and not blinking.
2Press the RESET button and hold it until the SYS LED begins to blink. (This usually takes about five
seconds.)
3Release the RESET button, and wait for the UAG to restart.
