From the main menu of the browser interface, under Advanced, click LAN IP Setup to view

the LAN IP Setup menu.

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 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

The LAN IP address of the router.

•

IP Subnet Mask

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 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 sent by the router.

(It recognizes both formats when receiving.) The default setting is RIP-1.

—

RIP-1 is universally supported. RIP-1 is usually adequate unless you have an unusual

network setup.

—

RIP-2 carries more information. RIP-2B uses subnet broadcasting.

Using the Router as a DHCP server

By default, the router functions as a DHCP 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

“Internet Networking and TCP/IP Addressing” 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

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.

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 use another device on your network as the DHCP server, or to manually configure the network

settings of all of your computers, deselect Use Router as DHCP Server. Otherwise, leave it

selected. If you deselect this service and no other DHCP server is available on your network, you

will need to set your computers’ IP addresses manually or they will not be able to access the router.

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 Add.

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 Edit or Delete.

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.

Using a Dynamic DNS Service

If your Internet Service Provider (ISP) gives you 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.

Your router contains a client that can connect to the dynamic DNS service provided by

DynDNS.org. You must first visit their website at

www.dyndns.org

and obtain an account and host

name, which you will configure in the router. Then, whenever your ISP-assigned IP address

changes, your router will automatically contact the dynamic DNS service provider, log in to your

account, and register your new IP address. If your host name is

hostname

, you will be able to reach

your router at

hostname.dyndns.org

.

From the main menu of the browser interface, under Advanced, click on Dynamic DNS to view

the Dynamic DNS menu.

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.

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 checkbox for Use a Dynamic DNS Service.

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.

This is the name you use to log in to your account, not your host name.

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 can

select the Use Wildcards checkbox 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 the WAN Setup Options

The WAN Setup options let you configure a DMZ (De-Militarized Zone) server, change the

Maximum Transmit Unit (MTU) size, and enable the wireless router to respond to a ping on the

WAN port. From the main menu of the browser interface, under Advanced, click WAN Setup to

view the WAN Setup menu.
