Configuring Network Overview
1 Overview
The Network module provides basic router functions, including WAN connection, DHCP
service, VLAN, IPTV service and more.
1.1 Supported Features
WAN
The router can provide a maximum of four WAN ports. Each WAN port has its own internet
connection, providing link backup and load balancing.
LAN
For LAN configuration, you can configure the LAN IP address and DHCP (Dynamic Host
Configuration Protocol) server. With its DHCP server enabled, the router can automatically
assign IP addresses to hosts in the LAN.
IPTV
IPTV services is based on the Internet protocol, rather than through traditional satellite
signal or cable transmission.
The router supports three kinds of IPTV configuration according to your ISP：
IPTV based on IGMP.
IPTV in Bridge mode.
IPTV in Custom mode.
MAC
You can change the default MAC address of the WAN port or LAN port according to your
needs.
Switch
The router supports some basic switch port management functions, like Port Mirror, Rate
Control, Flow Control and Port Negotiation, to help you to monitor the traffic and manage
the network effectively.
VLAN
The router supports 802.1Q VLAN, which can divide the LAN into multiple VLANs, helping
to manage the network more effectively.
IPv6
You can set up an IPv6 internet connection if your ISP provides IPv6 service.
Configuring Network WAN Configuration
User Guide 13
2 WAN Configuration
You can configure at most four WAN ports. Each WAN port can have its own WAN
connection, providing link backup and load balancing.
To complete WAN configuration, follow these steps:
1) Configure the number of WAN ports.
2) Configure the WAN connection.
2.1 Configuring the Number of WAN Ports
Choose the menu Network > WAN > WAN Mode to load the following page.
Figure 2-1 Configuring the WAN Mode
WAN Mode Specify the number of WAN ports.
1: Configure physical interface 1 as WAN1.
2: Configure physical interface 1 and interface 2 as WAN1 and WAN2 respectively.
3: Configure physical interface 1, interface 2 and interface3 as WAN1, WAN2 and
WAN3 respectively.
4: Configure physical interface 1, interface 2, interface 3 and interface 4 as WAN1,
WAN2, WAN3 and WAN4 respectively.
Note:
• When a WAN port is added, a port-related tab is automatically added; when a WAN port is de-
leted, the port-related tab is automatically deleted.
• The router will reboot after switching the WAN mode.
2.2 Configuring the WAN Connection
The router supports six connection types: Static IP, Dynamic IP, PPPoE, L2TP, PPTP and
BigPond Cable, you can choose one according to the service provided by your ISP.
User Guide 14
Configuring Network WAN Configuration
Static IP: If your ISP provides you with a fixed IP address and the corresponding
parameters, choose Static IP.
Dynamic IP: If your ISP automatically assigns the IP address and the corresponding
parameters, choose Dynamic IP.
PPPoE: If your ISP provides you with a PPPoE account, choose PPPoE.
L2TP: If your ISP provides you with an L2TP account, choose L2TP.
PPTP: If your ISP provides you with a PPTP account, choose PPTP.
BigPond Cable: If your ISP provides you with a BigPond Cable account, choose BigPond
Cable. BigPond Cable is only available for Australian users.
Configuring the Dynamic IP
Choose the menu Network > WAN > WAN to load the following page.
Figure 2-2 Configuring the Dynamic IP
In the Connection Configuration section, select the connection type as Dynamic IP. Enter
the corresponding parameters and click Save.
Connection Type Choose the connection type as Dynamic IP if your ISP automatically assigns the IP
address.
Host Name Optional. Enter a name for the router. It is null by default.
Upstream
Bandwidth
Specify the upstream bandwidth of the WAN port. The value configured here is the
upper limit of the “Maximum Upstream Bandwidth” on Transmission > Bandwidth
Control > Bandwidth Control page, to make “Bandwidth Control” take effect, please
ensure this parameter is set correctly.
Downstream
Bandwidth
Specify the downstream bandwidth of the WAN port. The value configured here is the
lower limit of the “Maximum Downstream Bandwidth” on Transmission > Bandwidth
Control > Bandwidth Control page, to make “Bandwidth Control” take effect, please
ensure this parameter is set correctly.
Configuring Network WAN Configuration
User Guide 15
MTU Specify the MTU (Maximum Transmission Unit) of the WAN port.
MTU is the maximum data unit transmitted in the physical network. When Dynamic
IP is selected, MTU can be set in the range of 576-1500 bytes. The default value is
1500.
Primary/
Secondary DNS
Optional. Enter the IP address of the DNS server provided by your ISP.
VLAN Add the WAN port to a VLAN. Generally, you don’t need to manually configure it
unless required by your ISP.
By default, the WAN port is automatically assigned to a VLAN, and the egress rule of
the VLAN is UNTAG, so the packets are transmitted by the WAN port without VLAN
tags. If you want the WAN port to transmit packets with VLAN tag, you need to create
the corresponding VLAN first and configure its egress rule as TAG, then manually
add the WAN port to that VLAN. To create VLANs, go to Network > VLAN > VLAN.
Note: When using the IPTV function, either in Bridge mode or Custom mode,
the router will automatically create corresponding VLANs after you finished the
configuration, and add port 1 (WAN 1) to the VLANs. Users cannot then manually
select the VLAN that WAN 1 belongs to.
Get IP using
Unicast DHCP
The broadcasting requirement may not be supported by a few ISPs. Select this
option if you can not get the IP address from your ISP even with a normal network
connection. This option is not required generally.

By default, the WAN port is automatically assigned to a VLAN, and the egress rule of
the VLAN is UNTAG, so the packets are transmitted by the WAN port without VLAN
tags. If you want the WAN port to transmit packets with VLAN tag, you need to create
the corresponding VLAN first and configure its egress rule as TAG, then manually
add the WAN port to that VLAN. To create VLANs, go to Network > VLAN > VLAN.
Note: When using the IPTV function, either in Bridge mode or Custom mode,
the router will automatically create corresponding VLANs after you finished the
configuration, and add port 1 (WAN1) to the VLANs. Users cannot then manually
select the VLAN that WAN 1 belongs to.

Lease time defines how long the clients can use the IP address assigned by the DHCP
server. Generally, the client will automatically request the DHCP server for extending
the lease time before the lease expired. If the request failed, the client will have to stop
using that IP address when the lease finally expired, and try to get a new IP address
from the other DHCP servers.

If a client requests option 60, the server will respond a packet containing the option
60 configured here. And then the client will compare the received option 60 with its
own. If they are the same, the client will accept the IP address assigned by the server,
otherwise the assigned IP address will not be accepted.
Option 138 Optional. Specify the option 138, which can be configured as the management IP

Configure IPTV based on IGMP.
Configure IPTV in Bridge mode.
Configure IPTV in Custom mode.
4.1 Configuring IPTV Based on IGMP
Some ISPs provide IPTV service based on IGMP technology. In this scenario, you can just
enable IGMP snooping and IGMP proxy, and connect your STB (Set-Top Box) to any LAN
port of the router. The IPTV stream will then be transmitted to the corresponding LAN port.
Choose the menu Network > IPTV> IPTV to load the following page.

IGMP Snooping Check the box to enable IGMP Snooping.
Without IGMP Snooping, the router will broadcast multicast stream to all LAN ports,
even though some LAN ports are not connected to any multicast member.
With IGMP Snooping enabled, the LAN ports listen IGMP packets transmitted between
the router and the clients and build a multicast table. The multicast table records the
multicast members and the corresponding connected LAN port. So the multicast
stream will be transmitted to only the ports that connected to multicast members.
IGMP Proxy Check the box to enable IGMP Proxy.
IGMP Proxy sends IGMP querier packets to the LAN ports to detect if there is any
multicast member connected to the LAN ports.
IGMP Version Choose the IGMP version as V2 or V3. The default is IGMP V2.

Configuring Transmission Transmission
1 Transmission
1.1 Overview
Transmission function provides multiple traffic control measures for the network. You can
configure the transmission function according to your actual needs.
1.2 Supported Features
The transmission module includes NAT, Bandwidth Control, Session Limit, Load Balancing
and Routing.
NAT
NAT (Network Address Translation) is the translation between private IP and public IP.
NAT provides a way to allow multiple private hosts to access the public network using one
public IP at the same time, which alleviates the shortage of IP addresses. Furthermore, NAT
strengthens the LAN (Local Area Network) security since the address of LAN host never
appears on the internet. The router supports following NAT features:
Multi-Nets NAT
Multi-Nets NAT function can help the router provide NAT translation for multiple subnets.
One-to-One NAT
One-to-One NAT creates a relationship between a private IP address and a public IP
address. A device with a private IP address can be accessed through the corresponding
valid public IP address.
Virtual Servers
When you build up a server in the local network and want to share it on the internet, Virtual
Servers can realize the service and provide it to the internet users. At the same time
Virtual Servers can keep the local network safe as other services are still invisible from the
internet.
Port Triggering
Port Triggering is a feature used to dynamically forward traffic on a certain port to a
specific server on the local network. When a host in the local network initiates a connection
to the triggering port, all the external ports will be opened for subsequent connections. The
router can record the IP address of the host, when the data from the internet returns to the
Configuring Transmission Transmission
User Guide 65
external ports, the router can forward them to the corresponding host. Port Triggering is
mainly applied to online games, VoIPs, video players and so on.
NAT-DMZ
When a PC is set to be a DMZ (Demilitarized Zone) host in the local network, it is totally
exposed to the internet, which can realize the unlimited bidirectional communication
between internal hosts and external hosts. The DMZ host becomes a virtual server with
all ports opened. When you are not clear about which ports to open in some special
applications, such as IP camera and database software, you can set the PC to be a DMZ
host.
ALG
Some special protocols such as FTP, H.323, SIP, IPSec and PPTP will work properly only
when ALG (Application Layer Gateway) service is enabled.
Bandwidth Control
You can control the bandwidth by configuring bandwidth control rules for limiting various
data flows. In this way, the network bandwidth can be reasonably distributed and utilized.
Session Limit
The amount of TCP and UDP sessions supported by the router is finite. If some local hosts
transmit too many TCP and UDP sessions to the public network, the communication quality
of the other local hosts will be affected, thus it is necessary to limit the sessions of those
hosts.
Load Balancing
You can configure the traffic sharing mode of the WAN ports to optimize the resource
utilization.
Routing
You can configure policy routing rules and static routing.
Policy routing provides a more accurate way to control the routing based on the policy
defined by the network administrator.
Static routing is a form of routing that is configured manually by adding non-aging entries
into a routing table. The manually-configured routing information guides the router in
forwarding data packets to the specific destination.

Configuring Firewall Firewall
1 Firewall
1.1 Overview
Firewall is used to enhance the network security. It can prevent external network threats from
spreading to the internal network, protect the internal hosts from ARP attacks, and control the
internal users’ access to the external network.
1.2 Supported Features
The Firewall module supports four functions: Anti ARP Spoofing, Attack Defense, MAC Filtering
and Access Control.
Anti ARP Spoofing
ARP (Address Resolution Protocol) is used to map IP addresses to the corresponding MAC
addresses so that packets can be delivered to their destinations. However, since ARP is
implemented with the premise that all the hosts and gateways are trusted, there are high
security risks on real, complex networks. If attackers send ARP spoofing packets with false IP
address-to-MAC address mapping entries, the device will update the ARP table based on the
false ARP packets and record wrong mapping entries, which results in a breakdown of normal
communication.
Anti ARP Spoofing can protect the network from ARP spoofing attacks. It works based on the
IP-MAC Binding entries. These entries record the correct one-to-one relationships between IP
addresses and MAC addresses. When receiving an ARP packet, the router checks whether it
matches any of the IP-MAC Binding entries. If not, the router will ignore the ARP packets. In this
way, the router maintains the correct ARP table.
In addition, the router provides the following two sub functions:
Permitting the packets matching the IP-MAC Binding entries only and discarding other
packets.
Sending GARP packets to the hosts when it detects ARP attacks. The GARP packets can
inform hosts of the correct ARP table, preventing their ARP tables from being falsified by
ARP spoofing packets.
Attack Defense
Attacks on a network device can cause device or network paralysis. With the Attack Defense
feature, the router can identify and discard various attack packets which are sent to the CPU,
and limit the packet receiving rate. In this way, the router can protect itself and the connected
network against malicious attacks.
Configuring Firewall Firewall
User Guide 93
The router provides two types of Attack Defense: Flood Defense and Packet Anomaly Defense.
Flood Defense limits the receiving rate of the specific types of packets, and Packet Anomaly
Defense discards the illegal packets directly.
MAC Filtering
MAC Filtering can flexibly control the access to the network of the specific hosts. You can
simply add the MAC addresses of the hosts to the MAC Filtering List and specify the filtering
rule for these hosts. Two rules are provided: allow the packets with the MAC addresses in the
MAC Filtering List and deny other packets, or deny the packets with the MAC addresses in the
MAC Filtering List and allow other packets.
Access Control
Access Control can filter the packets passing through the router based on the Access Control
rules. An Access Control rule includes a filter policy and some conditions, such as service
type, receiving interface and effective time. The router will apply the filter policy to the packets
matching these conditions, and thus to limit network traffic, manage network access behaviors
and more.
Access Control can prevent various network attacks, such as attacks on TCP (Transmission
Control Protocol) and ICMP (Internet Control Message Protocol) packets, and can also manage
network access behaviors, such as controlling access to the internet.

In Firewall module, you can configure the following features:
Anti ARP Spoofing

2.1 Anti ARP Spoofing
To complete Anti ARP Spoofing configuration, there are two steps. First, add IP-MAC Binding
entries to the IP-MAC Binding List. Then enable Anti ARP Spoofing for these entries.
Note:
In case Anti ARP Spoofing causes access problems to the currently connected devices, we
recommend that you add and verify the IP-MAC Binding entries first before enabling Anti ARP
Spoofing.
2.1.1 Adding IP-MAC Binding Entries
You can add IP-MAC Binding entries in two ways: manually and via ARP scanning.
Adding IP-MAC Binding Entries Manually
You can manually bind the IP address, MAC address and interface together on the condition
that you have got the related information of the hosts on the network.
Adding IP-MAC Binding Entries via ARP Scanning
With ARP Scanning, the router sends the ARP request packets with the specific IP field to the
hosts. Upon receiving the ARP reply packet, the router can get the IP address, MAC address
and connected interface of the host.
The following sections introduce these two methods in detail.

ARP Scanning to facilitate your operation.
Note:
Before using this feature, make sure that your network is safe and the hosts are not suffering from
ARP attacks at present; otherwise, you may obtain incorrect IP-MAC Binding entries. If your network
is being attacked, it’s recommended to bind the entries manually.

3 Configuration Examples
3.1 Example for Anti ARP Spoofing
3.1.1 Network Requirements
In the diagram below, several hosts are connected to the network via a layer 2 switch, and the
router is the gateway of this network. Since there exists the possibility that the attacker will
launch a series of ARP attacks, it is required to configure the router to protect itself and the
terminal hosts from the ARP attacks.

3.1.2 Configuration Scheme
The attacker can launch three types of ARP attacks: cheating gateway, imitating gateway
and cheating terminal hosts. The following section introduces the three ARP attacks and the
corresponding solutions.
Cheating Gateway
Cheating gateway attack is aimed at the router.
Configuring Firewall Configuration Examples
User Guide 105
The attacker pretends to be legal terminal hosts and sends fake ARP packets to the router,
cheating the router into recording wrong ARP maps of the hosts. As a result, packets from the
gateway cannot be correctly sent to the hosts. To protect the router from this kind of attack,
you can configure Anti ARP Spoofing on the router.
Imitating Gateway and Cheating Hosts
These two attacks are aimed at the terminal hosts.
Imitating Gateway means that the attacker imitates the gateway and sends fake ARP packets
to the hosts. As a result, the hosts record wrong ARP map of the gateway and cannot send
packets to the router correctly.
Cheating Hosts means that the attacker pretends to be a legal host and sends fake ARP
packets to other hosts. As a result, the cheated hosts record an incorrect ARP map of the legal
host and cannot send packets to legal host correctly.
To protect the hosts from the attacks above, it is recommend to take both of the precautions
below.
»Configure the firewall feature on the hosts.
»Configure the router to send GARP packets to the hosts when the router detects ARP
attacks. The GARP packets will inform the hosts of the correct ARP maps, and the wrong
ARP maps in the hosts will be replaced by the correct ones.
In conclusion, to protect the network from ARP attacks, we should make sure both the router
and the hosts are configured with the relevant ARP defense features. Here we introduce how to
configure Anti ARP Spoofing on the router. There are mainly three steps:
1) Get the IP and MAC addresses of the legal hosts and bind them to the IP-MAC Binding list.
2) Enable Anti ARP Spoofing.
3) Configure the router to send GARP packets when ARP attacks are detected.
3.1.3 Configuration Procedure
Follow the steps below to configure Anti ARP Spoofing on the router:
1) Choose the menu Firewall > Anti ARP Spoofing > IP-MAC Binding to load the following
page. In the IP-MAC Binding List section, click Add.

Host A, we keep Export to DHCP Address Reservation as “Enable" to preserve this IP
address from being assigned to other hosts. Keep Status of this entry as “Enable”. Click OK.

To meet these requirements, we can configure Access Control rules on the router to filter
the specific types of packets from R&D department: only the HTTP and HTTPs packets are
allowed to be sent to the internet, and other types of packets are not allowed. The configuration
overview is as follows:
1) Add an IP group for the R&D department in the Preferences module.
2) By default, the HTTP service type already exists, and you need to add HTTPs to the Service
Type list in the Preferences module.
3) Create two rules to allow the HTTP and HTTPs packets from the R&D department to be sent
to the WAN.

1.1 Overview
With the Behavior Control feature, you can control the online behavior of local hosts. You can
block specific hosts’ access to specific websites using URLs or keywords, block HTTP posts
and prevent certain types of files from being downloaded from the internet.
1.2 Supported Features
The Behavior Control module supports two features: Web Filtering and Web Security.
Web Filtering
Web Filtering is used to filter specific websites. The router provides two ways to filter websites:
Web Group Filtering and URL Filtering.
Web Group Filtering: You can configure multiple websites as a web group, and set a filtering
rule for the group. More than one group can be created and several groups can share a
same filtering rule.
URL Filtering: You can directly set a filtering rule for specific entire URLs or keywords.
Web Security
Web Security is used to control the specific online behaviors of local users. You can configure
this feature to block HTTP post, which means that the local users cannot log in, submit
comments or perform any other operation which needs HTTP post. Also, you can prohibit local
users from downloading specific types of files from the internet.

Configuring VPN VPN
Note:
TL-ER5120 does not support VPN function.
1 VPN
1.1 Overview
VPN (Virtual Private Network) provides a means for secure communication between
remote computers across a public wide area network (WAN), such as the internet. Virtual
indicates the VPN connection is based on the logical end-to-end connection instead of the
physical end-to-end connection. Private indicates users can establish the VPN connection
according to their requirements and only specific users are allowed to use the VPN
connection.
The core of VPN is to realize tunnel communication, which fulfills the task of data
encapsulation, data transmission and data decompression via the tunneling protocol.
Common tunneling protocols are Layer 2 tunneling protocol and Layer 3 tunneling
protocol.
Figure 1-1 Typical Topology of VPN
Remote Client
Gateway (Client)
Enterprise Server
Gateway (Server)
Internet
VPN Tunnel
1.2 Supported Features
The router supports Layer 2 tunneling protocol (PPTP, L2TP) and Layer 3 tunneling
protocol (IPSec).
PPTP
PPTP (Point-to-Point Tunneling Protocol) is a network protocol that enables the secure
transfer of data from a remote client to a private enterprise server by creating a VPN
across TCP/IP-based data networks. PPTP supports on-demand, multiprotocol, virtual
private networking over public networks, such as the internet.
L2TP
L2TP (Layer 2 Tunneling Protocol) provides a way for a dialup user to make a virtual Point-
to-Point Protocol (PPP) connection to an L2TP network server (LNS), which can be a
Configuring VPN VPN
User Guide 131
security gateway. L2TP sends PPP frames through a tunnel between an L2TP access
concentrator (LAC) and the LNS. Because of the lack of confidentiality inherent in the L2TP
protocol, it is often implemented along with IPSec.
IPSec
IPSec (IP Security) can provide security services such as data confidentiality, data integrity
and data authentication at the IP layer. IPSec uses IKE (Internet Key Exchange) to handle
negotiation of protocols and algorithms based on the user-specified policy, and to
generate the encryption and authentication keys to be used by IPSec. IPSec can be used
to protect one or more paths between a pair of hosts, between a pair of security gateways,
or between a security gateway and a host. The security gateway refers to a device which
implements IPSec protocol. For example, a router or a firewall implementing IPSec is a
security gateway.

Configuring Authentication Overview
1 Overview
Portal authentication, also known as Web authentication, is usually deployed in a guest-
access network (like a hotel or a coffee shop) to control the client’s internet access. In
portal authentication, all the client’s HTTP requests will be redirected to an authentication
page first. The client needs to enter the account information on the page to authenticate,
then can visit the internet after the authentication succeeded.
1.1 Typical Topology
The typical topology of portal authentication is shown as below:
Figure 1-1 Topology of Portal Authentication
Client
Access Device
Web Server
Authentication Server
Client
The end device that needs to be authenticated before permitted to access the internet.
Access Device
The device that supports portal authentication. In this user guide, it means the router. The
Access Device helps to: redirect all HTTP requests to the Web Server before authenticated;
interact with the Authentication Server to authenticate the client during the authentication
process; permit users to access the internet after the authentication succeeded.
Web Server
The web server responds to client’s HTTP requests, and returns an authentication login
page.
Authentication Server
The authentication server records the information of the user’s account, and interacts with
the access device to authenticate clients.

Router Web Server Authentication Server
1) The client is connected to the router but not authenticated, and starts to visit the
internet through HTTP;
2) The router redirects the client’s HTTP request to the web server;
3) The client visits the web server;
4) The Web server returns the authentication login page to the client;
5) The client enters the username and password on the authentication login page;
6) The router forwards the username and password to the authentication server;
7) The authentication server returns the authentication result to the router;
8) The router replies to the client with the authentication result;
9) The client visits the internet after the authentication succeeded.
1.3 Supported Features
To configure portal authentication, you need to configure both the web server and the
authentication server. The web server provides the authentication page for login; the
authentication server records the account information and authenticates the clients.
User Guide 164
Configuring Authentication Overview
1.3.1 Supported Web Server
The router has a built-in web server and also supports external web server. You can
configure the authentication page either using the built-in server or the external server.
Custom Page
You can use the built-in web server and customize the authentication page on your router.
External Links
You can specify the external web server and configure the authentication page on the
external web server.
1.3.2 Supported Authentication Server
The router provides three types of portal authentication:
Radius Authentication
In Radius authentication, you can specify an external Radius server as the authentication
server. The user’s account information are recorded in the Radius server.
Local Authentication
If you don’t have an additional Radius server, you can choose local authentication. In local
authentication, the router uses the built-in authentication server to authenticate. The built-
in authentication server can record at most 500 local user accounts, and each account is
can be used for at most 1024 clients to authenticate.

Managing Services Services
1 Services
1.1 Overview
The Services module incorporates two functions, Dynamic DNS (DDNS) and UPnP (Universal
Plug and Play) to provide convenient network services.
1.2 Support Features
Dynamic DNS
Nowadays, network protocols such as PPPoE and DHCP are widely employed by ISPs to
assign public IP addresses to users. The use of these protocols can cause the user’s public
IP address to change dynamically. DDNS is an internet service that ensures a fixed domain
name can be used to access a network with a varying public IP address. This means the
user’s network can be more easily accessed by internet hosts.
UPnP
With the development of networking and advanced computing techniques, greater
numbers of devices feature in networks. UPnP is designed to solve the problem of
communication between these network devices. UPnP function allows devices dynamically
discover and communicate with each other without additional configurations. For example,
it allows the download of P2P software without opening ports.

Managing Services Configuration Example for Dynamic DNS
4 Configuration Example for Dynamic DNS
4.1 Network Requirement
Host A gets internet services from an ISP (Internet Service Provider) via a PPPoE dial-up
connection. The user wants to visit the router’s web management interface using another
host on the internet.
Figure 4-1 Network Topology
Internet
Internet HostHost A Router
4.2 Configuration Scheme
For security management, the internet hosts attempting to manage the router must be
permitted by the router. Remote Management is used to manage the IP addresses of these
hosts.
Because the user uses PPPoE to access to the network, the public IP address of the router
may be changed each time the dial-up connection is established. When the public IP
address of the router changes, DDNS service ensures the DNS server rebinds the current
domain name to the new IP address. This means the user can always reach the router using
the same domain name, even if the public IP address has been changed.
4.3 Configuration Procedure
4.3.1 Specifying the IP Address of the Host
Before configuring DDNS, it is required to specify the IP address of the internet host
for remote management. For details, go to System Tools > Admin Setup > Remote
Management page.
4.3.2 Configuring the DDNS function
There are four DDNS servers supported by the router, we take Peanuthull DNS as an
example here.
