1.5.6.1 WPS
Your NR2101 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure WiFi network.
WPS is an industry standard specification, defined by the WiFi Alliance.
WPS allows you to quickly set up a WiFi network with strong security, without having to configure security
settings manually. Each WPS connection works between two devices. Both devices must support WPS
(check each device’s documentation to make sure). When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set up
a secure network by themselves.
You can use the LCD screen of the NR2101 to activate WPS in order to quickly set up a WiFi network with
strong security.
Go to Settings > WPS, select WPS Enable, and then WPS connect appears. Go to WPS connect > WPS to
activate WPS or type WPS PIN to connect. The following screen displays.

APN & SIM PIN
6.1 Overview
This chapter discusses the NR2101’s APN & SIM PIN settings. Use these screens to configure your NR2101
for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It
connects your private networks such as a LAN (Local Area Network) and other networks, so that a
device in one location can communicate with devices in other locations.
3G, 4G, and 5G wireless technology standards for the sending and receiving of voice, video, and data
in a mobile environment. You can insert a 5G SIM card and set the NR2101 to use this 3G/4G/5G
connection as your WAN.
Figure 47 LAN/Wireless LAN and Wireless WAN
6.1.1 What You Can Do in this Chapter
• Use the APN Settings screen to configure the APN (Access Point Name) settings (Section 6.2 on page
55).
• Use the SIM PIN Setting screen to enable SIM PIN lock (Section 6.3 on page 56).
6.1.2 What You Need To Know
3G
3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is optimized as
multiple users share the same channel and bandwidth is only allocated to users when they send data. It
allows fast transfer of voice and non-voice data and provides broadband Internet access to mobile
devices.
Chapter 6 APN & SIM PIN
NR2101 User’s Guide
54
4G
4G is the fourth generation of the mobile telecommunications technology and a successor of 3G. Both
the WiMAX and Long Term Evolution (LTE) standards are the 4G candidate systems. 4G only supports all-
IP-based packet-switched telephony services and is required to offer gigabit speed access.
5G
5G is the fifth generation of the mobile telecommunications technology that delivers exceptionally high
bandwidth and low latency. 5G is expected to bring about a band new uniform user experience using
massive IoT devices.
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa,
for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important
because without it, you must know the IP address of a computer before you can access it.
The NR2101 can get the DNS server addresses in the following ways.
1The 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 IPv6 DNS server fields.
2If your ISP dynamically assigns the DNS server IP addresses (along with the NR2101’s WAN IP address), set
the DNS server fields to get the DNS server address from the ISP.
IPv6 Introduction
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in
IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. The NR2101
can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and supports IPv6 rapid deployment
(6RD).
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an
example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be
written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can
only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be
written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
Chapter 6 APN & SIM PIN
NR2101 User’s Guide
55
IPv6 Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6
prefix length specifies how many most significant bits (start from the left) in the address compose the
network address. The prefix length is written as “/x” where x is a number. For example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.
IPv6 Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into
eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character
(1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters. For example,
FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.

CHAPTER 7
WLAN & WWAN
7.1 Overview
This chapter discusses how to configure the wireless network settings in your NR2101.
The following figure provides an example of a wireless network.
Figure 51 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B are called
wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the
printer) or with the Internet. Your NR2101 is the AP.
7.1.1 What You Can Do in this Chapter
• Use the SSID Settings screen to configure the wireless LAN (2.4G/5G) and select wireless security
modes (Section 7.2 on page 60).
• Use the WPS Settings screen to activate WPS via a PIN code (Section 7.3 on page 66).
• Use the MAC Filter screen to deny wireless clients based on their MAC addresses from connecting to
the NR2101 (Section 7.4 on page 67).
• Use the WWAN Settings screen to configure the WWAN settings on the NR2101 for Internet access
(Section 7.5 on page 68).
Chapter 7 WLAN & WWAN
NR2101 User’s Guide

7.1.2 What You Need to Know
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific channel, or frequency,
to send and receive information.
• Every wireless client in the same wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network. It can also protect the
information that is sent in the wireless network.
Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless
network.
SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the
SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the
default SSID to something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for unauthorized devices to get the
SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network.
MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is
usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02.
To get the MAC address for each wireless client, see the appropriate User’s Guide or other
documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use
the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the
correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless
network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network. Furthermore,
there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then,
they can use that MAC address to use the wireless network.
WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a wireless network with strong security, without having to configure security
1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These
kinds of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

settings manually. Depending on the devices in your network, you can either press a button (on the
device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices.
Then, they connect and set up a secure network by themselves. See how to set up a secure wireless
network using WPS in the Section 7.3 on page 66.

CHAPTER 8
NAT
8.1 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.
The figure below is a simple illustration of a NAT network. 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 192.168.1.35 to a third (C in the example).
You assign the LAN IP addresses to the devices (A to D) connected to your NR2101. The ISP assigns the
WAN IP address. The NAT network appears as a single host on the Internet. All traffic coming from A to D
going out to the Internet use the IP address of the NR2101, which is 192.168.1.1.
Figure 64 NAT Example
Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the
WAN to be forwarded through the NR2101.
8.1.1 What You Can Do
• Use the NAT Settings screen to configure your NR2101’s VPN pass-through and port forwarding settings
(Section 8.2 on page 76).
Chapter 8 NAT
NR2101 User’s Guide
75
8.1.2 What You Need to Know
Inside/Outside
Inside/outside denotes where a host is located relative to the NR2101, for example, the computers of
your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Global/Local
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for example,
the local address refers to the IP address of a host when the packet is in the local network, while the
global address refers to the IP address of the host when the same packet is traveling in the WAN side.
NAT
In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the
inside local address) to another (the inside global address) before forwarding the packet to the WAN
side. When the response comes back, NAT translates the destination address (the inside global address)
back to the inside local address before forwarding it to the original inside host.
NAT Types
This section discusses the following NAT types that are implemented on the NR2101.
•Full Cone: In full cone NAT, the NAT router maps all outgoing packets from an internal IP address and
port to a single IP address and port on the external network. The NAT router also maps packets
coming to that external IP address and port to the internal IP address and port.
•Address Restricted or Restricted Cone: As in full cone NAT, a restricted cone NAT router maps all
outgoing packets from an internal IP address and port to a single IP address and port on the external
network. The difference from full cone NAT is in how the restricted cone NAT router handles packets
coming in from the external network.
•Port Restricted: Port restricted cone NAT maps all outgoing packets from an internal IP address and
port to a single IP address and port on the external network.
•Symmetric: The full, restricted and port restricted cone NAT types use the same mapping for an
outgoing packet’s source address regardless of the destination IP address and port. In symmetric NAT,
the mapping of an outgoing packet’s source address to a source address in another network is
different for each different destination IP address and port.

8.3 Technical Reference
The following section contains additional technical information about the NR2101 features described in
this chapter.
8.3.1 NAT Port Forwarding: Services and Port Numbers
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you
can make accessible to the outside world even though NAT makes your whole inside network appear
as a single machine to the outside world.
Use the Port Forwarding screen to forward incoming service requests to the server(s) on your local
network. You may enter a single port number or a range of port numbers to be forwarded, and the local
IP address of the desired server. The port number identifies a service; for example, web service is on port
80 and FTP on port 21. In some cases, such as for unknown services or where one server can support
more than one service (for example both FTP and web service), it might be better to specify a range of
port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request that does
not have a server explicitly designated for it is forwarded to the default server. If the default is not
defined, the service request is simply discarded.
L2TP VPN Pass-Through Select Enable to allow VPN clients to make outbound L2TP connections. It is required
in order to connect to a L2TP VPN account. If L2TP is disabled, then when a client
sends a request to a VPN server, the server will reply to the NR2101 and the NR2101
will drop the request. When L2TP is enabled, the NR2101 will forward the reply from
the VPN server to the client that initiated the request, and the connection will
establish successfully.
Webserver WWAN Access Select Enable to activate remote web server management.
DMZ IP Enter the IP address of the default server which receives packets from ports that are
not specified in the port forwarding table.
Port Forwarding Port forwarding allows you to define the local servers to which the incoming services
will be forwarded. You can configure a new schedule rule by clicking Add Entry. You
can view the schedule rules by clicking Get Entries.
Serial: This field displays the serial number of an individual port forwarding server
entry.
Private IP: This field displays the IP address of the virtual server on the LAN.
Private port: A private port refers to the port number of a host when the packet is in
the LAN side.
Global port: A global port refers to the port number of the host when the same
packet is traveling in the WAN side.
Protocol: Select the protocol (TCP_UDP, TCP, UDP, or ICMP) used to transport the
packets for which you want to apply the rule.
Delete: Click Delete to delete an existing port forwarding rule.

Note: Many residential broadband ISP accounts do not allow you to run any server processes
(such as a Web or FTP server) from your location. Your ISP may periodically check for
servers and may suspend your account if it discovers any active services at your
location. If you are unsure, refer to your ISP.
8.3.2 NAT Port Forwarding Example
Let's say 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 192.168.1.35 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.
Figure 66 Multiple Servers Behind NAT Example
8.3.3 Trigger Port Forwarding
Some services use a dedicated range of ports on the client side and a dedicated range of ports on the
server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in
from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that
port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a
different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding
port with another LAN computer's IP address.
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns
using the service. The NR2101 records the IP address of a LAN computer that sends traffic to the WAN to
request a service with a specific port number and protocol (a "trigger" port). When the NR2101's WAN
port receives a response with a specific port number and protocol ("incoming" port), the NR2101
forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s
connection for that service closes, another computer on the LAN can use the service in the same
manner. This way you do not need to configure a new IP address each time you want a different LAN
computer to use the application.
8.3.4 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.

Figure 67 Trigger Port Forwarding Process: Example
1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a “trigger” port and causes the NR2101 to record Jane’s computer IP address. The NR2101
associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The NR2101 forwards the traffic to Jane’s computer IP address.
5Only Jane can connect to the Real Audio server until the connection is closed or times out. The NR2101
times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control
Protocol/Internet Protocol).
8.3.5 Two Points To Remember About Trigger Ports
1Trigger events only happen on data that is coming from inside the NR2101 and going to the outside.
2If an application needs a continuous data stream, that port (range) will be tied up so that another

CHAPTER 9
Firewall
9.1 Overview
Use these screens to enable and configure the firewall that protects your NR2101 and your LAN from
unwanted or malicious traffic.
Enable the firewall to protect your LAN devices from attacks by hackers on the Internet and control
access between the LAN and WAN. By default the firewall:
• Allows traffic that originates from your LAN devices to go to all of the networks.
• Blocks traffic that originates on the other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant Messaging)
session from the LAN to the WAN (1). Return traffic for this session is also allowed (2). However other traffic
initiated from the WAN is blocked (3 and 4).
Figure 68 Default Firewall Action
9.1.1 What You Can Do
• Use the Firewall Settings screen to configure predefined Internet services and firewall rules (Section 9.2
on page 82).

About the NR2101 Firewall
The NR2101’s firewall feature physically separates the LAN and the WAN and acts as a secure gateway
for all data passing between the networks.
It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when
activated (click the General tab under Firewall and then click the Enable check box). The NR2101's
purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The
NR2101 can be used to prevent theft, destruction and modification of data, as well as log events, which
may be important to the security of your network.
The NR2101 is installed between the LAN and a broadband modem connecting to the Internet. This
allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The LAN (Local Area Network) connects to a network of computers, which needs security from the
outside world. These computers will have access to Internet services such as e-mail, FTP and the World
Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to
use a specific service.
Guidelines For Enhancing Security With Your Firewall
1Change the default password via Web Configurator.
2Think about access control before you connect to the network in any way, including attaching a
modem to the port.
3Limit who can access your NR2101.
4Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a
potential security risk. A determined hacker might be able to find creative ways to misuse the enabled
services to access the firewall or the network.
5For local services that are enabled, protect against misuse. Protect by configuring the services to
communicate only with specific peers, and protect by configuring rules to block packets for the services
at specific interfaces.
6Protect against IP spoofing by making sure the firewall is active.
7Keep the firewall in a secured (locked) room.

CHAPTER 10
LAN Settings
10.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain
TCP/IP configuration at start-up from a server. You can configure the NR2101’s WLAN as a DHCP server
or disable it. When configured as a server, the NR2101 provides the TCP/IP configuration for the clients. If
DHCP service is disabled, you must have another DHCP server on your LAN, or else the computer must
be manually configured.
10.1.1 What You Can Do
• Use the LAN Settings screen to enable the LAN DHCP server and view the current DHCP client
information (Section 10.2 on page 86).
10.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
MAC Addresses
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned
at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. Find
out the MAC addresses of your network devices if you intend to add them to the DHCP Client List screen.
IP Pool Setup
The NR2101 is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64. This
configuration leaves 31 IP addresses (excluding the NR2101 itself) in the lower range (192.168.1.2 to
192.168.1.32) for other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that you may
have.
10.2 DHCP Server General Settings
The NR2101 has built-in DHCP server capability that assigns IP addresses to systems that support DHCP
client capability. Use this screen to enable the DHCP server. Click WLAN SETTINGS and the following
screen displays.

LAN DHCP Select Enable to activate DHCP for LAN.
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients (computers) to obtain TCP/IP configuration at startup from a server. Enable the
DHCP server unless your ISP instructs you to do otherwise. Select Disable to stop the
NR2101 acting as a DHCP server. When configured as a server, the NR2101 provides TCP/
IP configuration for the clients. If not, DHCP service is disabled and you must have another
DHCP server on your LAN, or else the computers must be manually configured. When set
as a server, fill in the following four fields.
LAN DHCP Start IP This field specifies the first of the contiguous addresses in the IP address pool for LAN.
LAN DHCP End IP This field specifies the last of the contiguous addresses in the IP address pool for LAN.
LAN DHCP Lease Time This is the period of time DHCP-assigned addresses is used. DHCP automatically assigns IP
addresses to clients when they log in. DHCP centralizes IP address management on
central computers that run the DHCP server program. DHCP leases addresses, for a
period of time, which means that past addresses are “recycled” and made available for
future reassignment to other systems.
