Advanced Configuration of the Router
v1.3, May 2006
Configuring LAN TCP/IP Setup Parameters
The router is shipped preconfigured to use private IP addresses on the LAN side, and to act.as a
DHCP server. The router’s default LAN IP configuration is:
LAN IP address—192.168.1.1
Subnet mask—255.255.255.0
These addresses are part of the IETF-designated private address range for use in private networks,
and should be suitable for most applications. If your network has a requirement to use a different
IP addressing scheme, you can make those changes in this menu.
The LAN IP parameters are:
IP Address
This is the LAN IP address of the router.
IP Subnet Mask
This is the LAN Subnet Mask of the router. Combined with the IP address, the IP Subnet Mask
allows a device to know which other addresses are local to it, and which must be reached
through a gateway or router.
RIP Direction
RIP (Router Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction selection controls how the router sends and receives RIP packets.
Both is the default.
When set to Both or Out Only, the router broadcasts its routing table periodically.
When set to Both or In Only, the router incorporates the RIP information that it receives.
When set to None, the router does not send any RIP packets and ignores any RIP packets
received.
RIP Version
This controls the format and the broadcasting method of the RIP packets that the router sends.
(It recognizes both formats when receiving.) By default, this is set for RIP-1.
RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you
have an unusual network setup.
RIP-2 carries more information. RIP-2B uses subnet broadcasting.
Note:
If you change the LAN IP address of the router while connected through the
browser, you will be disconnected. You must then open a new connection to the
new IP address and log in again.

Using the Router as a DHCP server
By default, the router functions as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the router's LAN. The assigned default gateway address is the LAN address of the router. The
router assigns IP addresses to the attached computers from a pool of addresses specified in this
menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See
“Wireless Communications” in Appendix B
for an explanation of DHCP and information about
how to assign IP addresses for your network.
Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.1.2 and
192.168.1.254, although you may wish to save part of the range for devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
An IP Address from the range you have defined
Subnet Mask
Gateway IP Address (the router’s LAN IP address)
Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the router’s LAN IP address)
Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu)
To select another device on your network as the DHCP server, or to manually configure the
network settings of all of your computers, clear the
Use Router as DHCP Server
check box.
Otherwise, leave it checked.
Using Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer will always
receive the same IP address each time it accesses the router’s DHCP server. Reserved IP addresses
should be assigned to computers or servers that require permanent IP settings.
To reserve an IP address:
1.
Click the
Add
button.
2.
In the IP Address box, type the IP address to assign to the computer or server.
(choose an IP address from the router’s LAN subnet, such as 192.168.1.x)

3.
Type the MAC Address of the computer or server.
4.
Click
Apply
to enter the reserved address into the table.
To edit or delete a reserved address entry:
1.
Click the button next to the reserved address you want to edit or delete.
2.
Click

or
Delete
.
Using a Dynamic DNS Service
If your network has a permanently assigned IP address, you can register a domain name and have
that name linked with your IP address by public Domain Name Servers (DNS). However, if your
Internet account uses a dynamically assigned IP address, you do not know in advance what your IP
address will be, and the address can change frequently. In this case, you can use a commercial
dynamic DNS service, which will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently-changing IP address.
The router contains a client that can connect to many popular dynamic DNS services. You can
select one of these services and obtain an account with them. Then, whenever your ISP-assigned
IP address changes, your router will automatically contact your dynamic DNS service provider,
log in to your account, and register your new IP address.
Tip:
If the computer is already present on your network, you can copy its MAC
address from the Attached Devices menu and paste it here.
Note:
The reserved address is not assigned until the next time the computer contacts
the router's DHCP server. Reboot the computer or access its IP configuration
and force a DHCP release and renew.
Note:
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the
dynamic DNS service will not work because private addresses are not routed on the
Internet.

From the main menu of the browser interface, under Advanced, click on
Dynamic DNS
.
To configure Dynamic DNS:
1.
Register for an account with one of the dynamic DNS service providers whose names appear
in the
Select Service Provider
box. For example, for dyndns.org, go to
www.dyndns.org
.
2.
Select the
Use a Dynamic DNS Service
check box.
3.
Select the name of your dynamic DNS Service Provider.
4.
Type the Host Name (or domain name) that your dynamic DNS service provider gave you.
5.
Type the User Name for your dynamic DNS account.
6.
Type the Password (or key) for your dynamic DNS account.
7.
If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may
select the
Use wildcards
check box to activate this feature.
For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same
IP address as yourhost.dyndns.org.
8.
Click
Apply
to save your configuration.

Configuring Static Routes
Static Routes provide additional routing information to your router. Under normal circumstances,
the router has adequate routing information after it has been configured for Internet access, and
you do not need to configure additional static routes. You must configure static routes only for
unusual cases such as multiple routers or multiple IP subnets located on your network.
From the main menu of the browser interface, under Advanced, click on
Static Routes
to view the
Static Routes menu, shown below.
To add or edit a Static Route:
1.
Click the
Add
button to open the Add/Edit Menu, shown below.
2.
Type a route name for this static route in the Route Name box.
(This is for identification purposes only.)
