_________________________________________________________________________________________________
TIP
DHCP (Dynamic Host Configuration Protocol) assigns an IP address to each device on the LAN/private network. When
you enable the DHCP Server, the DHCP Server will automatically allocate an unused IP address from the IP address pool
specified in this screen to the requesting device as long as the device is set to "Obtain an IP Address Automatically". By
default, DHCP is enabled.
IPv6 Autoconfig
Static LAN IPv6 Address Configuration
Interface Address (prefix length is required): Enter the interface address.
_________________________________________________________________________________________________
NOTE
1. IPv6 address can only be Aggregatable Global Unicast Addresses and Unique Local Address. Link-Local Unicast
Addresses and Multicast Addresses are not permitted.
2. The IPv6 address must be entered with a prefix length.
_________________________________________________________________________________________________
80
IPv6 LAN Applications
Enable DHCPv6 Server：Check to enable the DHCPv6 Server.
Stateless: If selected, IPv6 clients will generate IPv6 addresses automatically based on the Prefix Delegation's IPv6
prefix and their own MAC addresses.
Stateful: Stateful DHCPv6 is supported based on the assumption of prefix length less than 64. Select this option and
configure the start/end interface ID and leased time. The router will automatically assign IPv6 addresses to IPv6 clients.
Leased Time (hour): The lease time is a time length that the IP address is assigned to each device before it is refreshed.
Start interface ID/End interface ID: Specify the start/end interface ID Interface ID does NOT support ZERO
COMPRESSION "::". Please enter the complete information. For example: Please enter "0:0:0:2" instead of "::2".
Enable RADVD: The RADVD (Router Advertisement Daemon) implements link-local advertisements of IPv6 router
addresses and IPv6 routing prefixes using the Neighbor Discovery Protocol (NDP) and is used by system administrators
in stateless autoconfiguration methods of network hosts on Internet Protocol version 6 networks. Check the checkbox to
enable the RADVD.
Enable ULA Prefix Advertisement: If enabled, the router will advertise ULA prefix periodically
Randomly Generate: If selected, address prefix can be automatically generated.
Statically Configure: If you select this option, you need to manually configure the address prefix and life time.
Prefix: Specify the prefix.
Preferred Life Time (hour): Specify the preferred life time in hour.
Valid Life Time (hour): Specify the valid life time in hour.
Enable MLD Snooping: MLD is used by IPv6 routers for discovering multicast listeners on a directly attached link. If
disabled on layer2 devices, IPv6 multicast data packets will be broadcast on the entire layer2; if enabled, these packets
will be multicast to only specified recipient instead of being broadcast on the entire layer2.
_________________________________________________________________________________________________
TIP
If you change the LAN IP address of the device, the current connection to the device will be stopped. You must use the
new IP address to log in to the device. Be sure to write the new address on a sticky label and attach it to the bottom of the
unit. You will need the new address to log in to the device in the future.

4.2.4 NAT
This section explains the following:
• Virtual Server
• Port Triggering
• DMZ Host
• UPnP
Virtual Server
The Virtual Server is useful for web servers, ftp servers, e-mail servers, gaming and other specialized Internet
applications. When you enable the Virtual Server, the communication requests from the Internet to your router’s WAN
port will be forwarded to the specified LAN IP address.
To enter the virtual server screen, click NAT > Virtual Server and then click the Add button to add rules.
Use Interface: Select a WAN connection to which you wish to apply the rules. When there is only one WAN connection
available, the rules will be automatically applied to it.
Service Name:
- Select a Service: Allows you to select an existing service from the drop-down list.
- Custom Service: Allows you to customize a service.
Server IP Address: Enter the IP address of your local computer that will provide this service.
External Starting Port and External Ending Port: These are the starting number and ending number for the public
82
ports at the Internet interface.
Protocol: Select the protocol from the Protocol drop-down list. If you are unsure, select TCP/UDP.
Internal Starting Port and Internal Ending Port: These are the starting number and ending number for the ports of a
computer on the router’s local area network (LAN).
_________________________________________________________________________________________________
NOTE
If you have enabled the UPnP functionality on both the router and your PC that is attached to one of the LAN port of the
router, you will be prompted on the Virtual Server page that the UPnP interface is being used.
_________________________________________________________________________________________________
Instance
You have set up two servers on your LAN side:
- An FTP server (using the default port number of 21) at the IP address of 192.168.1.100
- A web server (using the default port number of 8080) at the IP address of 192.168.1.110
And want your friends on the Internet to access the FTP server and web server via default ports. To access your FTP or
web server from the Internet, a remote user has to know the WAN IP address of your router. In this example, we assume
the WAN IP address of your router is 183.37.227.201. Then follow instructions below:
To configure the router to make your local FTP server public:
Procedure
1. Click NAT > Virtual Server to enter it and then click the Add button.
2. Select FTP Server that you wish to host on your network from the Select a Service drop-down list. The port
number (21) used by this service will then be automatically populated.
- Or if you wish to define the service yourself, enter a descriptive name in the Custom Service, say My FTP, and
then manually enter the port number (21) used by this service in the Internal Starting Port, Internal Ending Port,
External Starting Port and External Ending Port fields.
3. Select a protocol from the Protocol drop-down list. If you are unsure, select TCP/UDP.
4. In the Server IP Address field, enter the last digit of the IP address of your local computer that offers this service.
Here in this example, we enter 100.
5. Click .
Your friends on the Internet will then be able to access your FTP server simply by "ftp://183.37.227.201:21".
83
To configure your router to make your local web server public:
Procedure
1. Click NAT > Virtual Server to enter it and then click the Add button.
2. Select Web Server (HTTP) that you wish to host on your network from the Select a Service drop-down list. The
port number (8080) used by this service will then be automatically populated.
- Or if you wish to define the service yourself, enter a descriptive name in the Custom Service, say My Web Server
(HTTP), and then manually enter the port number (8080) used by this service in the Internal Starting Port,
Internal Ending Port, External Starting Port and External Ending Port fields.
3. Select a protocol from the Protocol drop-down list. If you are unsure, select TCP/UDP.
4. In the Server IP Address field, enter the last digit of the IP address of your local computer that offers this service.
Here in this example, we enter 110.
5. Click .
Now you can view your configurations as seen in the screenshot below. Your friends on the Internet will then be able to
access the web server simply by entering "http://183.37.227.201:8080" in his browser.
_________________________________________________________________________________________________
NOTE
1. The "Internal Port End" cannot be modified directly. Normally, it is set to the same value as "External Port End".
However, if you modify "Internal Port Start", then "Internal Port End" will be set to the same value as "Internal Port
Start".
2. If the service or game you wish to host on your network is not included in the list, manually add it in the Custom
Service field and then add the port number used by it to the Internal Starting Port, Internal Ending Port, External
Starting Port and External Ending Port fields.
_________________________________________________________________________________________________
84
Port Triggering
Some applications such as games, video conferencing, remote access applications and others require that specific ports in
the Router's firewall be opened for access by the applications. Port Trigger dynamically opens up the 'Open Ports' in the
firewall when an application on the LAN initiates a TCP/UDP connection to a remote party using the 'Triggering Ports'.
The Router allows the remote party from the WAN side to establish new connections back to the application on the LAN
side using the 'Open Ports'.
To enter the Port Triggering screen, click NAT > Port Triggering and then click the Add button to add rules.
You can configure the port settings from this screen by selecting an existing application or creating your own (Custom
application) and click Save/Apply to add it.
Use Interface: Select a WAN connection to which you wish to apply the rules. When there is only one WAN connection
available, the rules will be automatically applied to it.
Application Name: Two options are available:
Select an application: Select one from the drop-down list directly.
- Custom application: Custom application by yourself.
Trigger Port Start/Trigger Port End: The port range for an application to initiate connections.
Trigger Protocol: Select the protocol from the drop-down list. If you are unsure, select TCP/UDP.
Open Port Start/ Open Port End: These are the starting number and ending number for the ports that will be
85
automatically opened by the built-in firewall when connections initiated by an application are established.
DMZ Host
The default DMZ (De-Militarized Zone) host feature is helpful when you are using some online games and
videoconferencing applications that are not compatible with NAT (Network Address Translation).
DMZ Host IP Address: The IP Address of the device for which the router’s firewall will be disabled. Be sure to assign a
static IP Address to that device. The DMZ host should be connected to a LAN port of the device. Be sure to assign a
static IP address to that DMZ host.
Warning!
DMZ servers pose a security risk. A computer designated as the DMZ server loses much of the protection of the firewall
and is exposed to exploits from the Internet.
UPnP
UPnP (Universal Plug and Play) allows Windows based systems to configure the device for various Internet applications
automatically. UPnP devices can automatically discover the services from other registered UPnP devices on the network.
If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications, like instant
messaging or remote assistance (a feature in Windows XP), you should enable UPnP.
86
Enable UPnP: Check/uncheck to enable/disable the UPnP feature.
_________________________________________________________________________________________________
NOTE
UPnP is activated only when there is a live WAN service with NAT enabled.

Static Route
Static routes provide additional routing information to your router. Typically, you do not need to add static routes.
However, when there are several routers in the network, you may want to set up static routing. Static routing determines
the path of the data in your network. You can use this feature to allow users on different IP domains to access the Internet
via this device. It is not recommended to use this setting unless you are familiar with static routing. In most cases,
dynamic routing is recommended, because this feature allows the router to detect the physical changes of the network
layout automatically.
Click Add to enter the following screen:
IP Version: Select IP version.
Destination IP address/prefix length: Enter the destination IP address and prefix length of the final destination.
Interface: Select an interface from the drop-down list.
Gateway IP address: Enter the gateway IP address, which must be a router on the same LAN segment as the
95
router.
Metric: Enter a number in the Metric field. This stands for the number of routers between your network and the
destination.
Apply /Save: Click to apply and save your settings.
_________________________________________________________________________________________________
NOTE
1. Destination IP address cannot be on the same IP segment as WAN or LAN segment as the router.
2. Only configure additional static routes for unusual cases such as multiple routers or multiple IP subnets located on
your network. Wrong static routes may lead to network failure.
3. For system created route, the “Remove” checkbox is disabled.
_________________________________________________________________________________________________
4.2.9 DNS
DNS Server (Static DNS)
The DNS server translates domain names to numeric IP addresses. It is used to look up site addresses based on their
names. If the DNS server works incorrectly, Internet access will be blocked.
DNS server is configured when you are setting up your Internet connectivity. So, you do not have to finish DNS server
setup here unless your network works false.
For IPv4
① Click Advanced Setup > DNS > DNS Server, and enter the screen below.
96
② Check the Select DNS Server Interface from available WAN interfaces option if the device gets a DNS
address automatically from an upstream device. Or select the Use the following Static DNS IP address option and
enter static DNS server address provided by your ISP.
③ Click Apply/Save at the bottom of the page.
For IPv6
① Click Advanced Setup > DNS > DNS Server, and enter the screen below.
② Select the Obtain IPv6 DNS info from a WAN interface option if the device gets a DNS server address from
the upstream device automatically. And select a configured WAN interface for the IPv6 DNS server information.
Or select the Use the following Static IPv6 DNS address option and enter the static IPv6 DNS server address
provided by your ISP.
③ Click Apply/Save.
NOTE
1. In ATM mode, if only a single PVC with IPoA or static IPoE protocol is configured, Static DNS server IP addresses
must be entered.
2. If you are not clear about the static DNS server IP information, ask your ISP to provide it.
3. The default settings are recommended if you are unsure about the DNS server addresses. If a wrong DNS server
address is configured, webpages may not be open.
Dynamic DNS (DDNS)
If your Internet service provider (ISP) gave you a static (fixed) public IP address, you can register a domain name and
have that name associated with your IP address by public Domain Name Servers (DNS). However, if your ISP gave you
a dynamic (changing) public IP address, you cannot predict what your IP address will be, and the address can change
frequently. In this case, you can use a commercial Dynamic DNS service. It allows you to register your domain to their
IP address and forward traffic directed at your domain to your frequently changing IP address. If your ISP assigns a
private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic DNS service does not work because private
97
addresses are not routed on the Internet.
Click Advanced Setup > DNS > Dynamic DNS to enter the Dynamic DNS screen.
Click to configure the DDNS settings.
D-DNS Provider: Select your DDNS service provider from the drop-down menu.
Hostname: Enter the DDNS domain name registered with your DDNS service provider.

⑤ Enter the password of DynDNS account.
Here is “123456789” for example.
⑥ Click to save your configuration.
4.2.10 DSL
This screen provides multiple ASDL modulation modes to meet diversified environments. You can also select phone line
pair and Capability.
DSL parameter configurations must be supported by ISP to take effect. Actual parameters (see Statistics-DSL) resulted
from the negotiation between your router and ISP. Wrong configurations may fail your Internet access.
The best DSL configurations are the factory defaults. Only change them with the support of your ISP or our technical
staff when your router fails to negotiate with ISP in DSL (ATM) mode.
99
Check the checkbox next to a modulation to enable it and then click .
Advanced Settings: Click it to enter the Advanced Settings screen as below.
