To add a default route
Add a default route to configure where the FortiGate-5000 module sends traffic
destined for an external network (usually the Internet). Adding the default route also
defines which interface is connected to an external network. The default route is not
required if the interface connected to the external network is configured using DHCP
or PPPoE.

System > Router > Static
.

If the Static Route table contains a default route (IP and Mask set to 0.0.0.0), select
the Delete icon to delete this route.

Select Create New.

Using the command line interface
You can also configure the FortiGate-5000 module using the command line interface
(CLI). For information about connecting to the CLI, see
“Connecting to the command
line interface (CLI)” on page 16
.
Note:
If you change the IP address of the interface you are connecting to, you must connect
through a web browser again using the new address. Browse to https:// followed by the new IP
address of the interface. If the new IP address of the interface is on a different subnet, you may
have to change the IP address of your computer to the same subnet.
