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 is 134.177.1.0.

When you first configured your router, two implicit static routes were created. A default route was

created with your ISP as the gateway, and a second static route was created to your local network

for all 192.168.1.x addresses. With this configuration, if you attempt to access a device on the

134.177.1.0 network, your router forwards your request to the ISP. The ISP forwards your request

to the company where you are employed, and the request will likely be denied by the company’s

firewall.

In this case you must define a static route, telling your router that 134.177.1.0 should be accessed

through the ISDN router at 192.168.1.100. The static route would look like Figure 7-7.

In this example:

• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to

all 134.177.1.x addresses.

• The Gateway IP Address fields specifies that all traffic for these addresses should be

forwarded to the ISDN router at 192.168.1.100.

• A Metric value of 1 will work since the ISDN router is on the LAN.

• Private is selected only as a precautionary security measure in case RIP is activated.
