Adding a default route
Add a default route to configure where the FortiGate unit 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.
To add a default route
1 Go to Router > Static.
2 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.
3 Select Create New.
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.
