firewall.
Type a number between 1 and 15 as the Metric value.

This represents the number of firewalls between your network and the destination. Usually, a
setting of 2 or 3 works, but if this is a direct connection, set it to 1.
Click Apply to have the static route entered into the table.
9.
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.
• Your company's network is 134.177.0.0.
When you first configured your firewall, 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 192.168.0.x addresses. With this configuration, if you attempt to access a device on
the 134.177.0.0 network, your firewall 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 example:
• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to
all 134.177.x.x addresses.
• Private is selected only as a precautionary security measure in case RIP is activated.
