Static Routes

Static routes provide additional routing information to your wireless router. Under normal

circumstances, the wireless router has adequate routing information after it has been

configured for Internet access, and you do not need to configure additional static routes. You

configure static routes only for unusual cases such as multiple routers or multiple IP subnets

located on your network.

Static Route Example

As an example of when a static route is needed, consider the following case:

• Your primary Internet access is through a cable modem to an ISP.

• You have an ISDN router on your home network for connecting to the company where

you are employed. This router’s address on your LAN is 192.168.1.100.

• Your company’s network address is 134.177.0.0.

When you first configured your wireless router, two implicit static routes were created. A

default route was created with your ISP as the wireless router, and a second static route was

created to your local network for all 192.168.0.x addresses. With this configuration, if you

attempt to access a device on the 134.177.0.0 network, your wireless router forwards your

request to the ISP. The ISP forwards your request to the company where you are employed,

and the request is likely to be denied by the company’s firewall.

In this case you need to define a static route,

telling your wireless router that 134.177.0.0

should be accessed through the ISDN router

at 192.168.0.100

In this example:

• The Destination IP Address and IP

Subnet Mask fields specify that this static

route applies to all 134.177.x.x

addresses.

• The Gateway IP Address field specifies

that all traffic for these addresses is to be

forwarded to the ISDN router at

192.168.0.100.

• The value in the Metric field represents

the number of routers between your

network and the destination. This is a direct connection, so it can be set to the minimum

value of 2.

• The Private check box is selected only as a precautionary security measure in case RIP

is activated.
