Static Route Example

As an example of when a static route is needed, consider the following case:
• Your primary Internet access is through the Model DG814 gateway 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 192.168.0.100.
• Your company's network is 134.177.0.0.
When you first configured your gateway, 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.x.x addresses. With this configuration, if you attempt to access a device on
the 134.177.0.0 network, your router will forward 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 134.177.0.0 should be accessed
through the ISDN router at 192.168.100. The static route would look like
Figure 5-5. Static Route Example
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 fields specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.
• A Metric value of either 1 or 2 will work.
• Private is selected only as a precautionary security measure in case RIP is activated.
