When you add a static route to the Static Route list, the FortiGate unit evaluates
the information to determine if it represents a different route compared to any
other route already present in the FortiGate routing table. If no route having the
same destination exists in the routing table, the FortiGate unit adds the route to
the routing table.
To view the list of static routes, go to Router > Static > Static Route. To edit an
existing static route entry, go to Router > Static > Static Route and select the
Edit icon beside the entry that you want to edit.
Figure 98 shows the static route list belonging to a FortiGate unit that has
interfaces named “external” and “internal”. The names of the interfaces on your
FortiGate unit may be different.

Default route and default gateway
In the factory default configuration, entry number 1 in the Static Route list is
associated with a destination address of 0.0.0.0/0.0.0.0, which means any/all
destinations. This route is called the “static default route”. If no other routes are
present in the routing table and a packet needs to be forwarded beyond the
FortiGate unit, the factory configured static default route causes the FortiGate unit
to forward the packet to the default gateway.
To prevent this you must either edit the factory configured static default route to
specify a different default gateway for the FortiGate unit, or delete the factory
configured route and specify your own static default route that points to the default
gateway for the FortiGate unit.
For example, consider Figure 99, which shows a FortiGate unit connected to a
router. To ensure that all outbound packets destined to any network beyond the
router are routed to the correct destination, you must edit the factory default
configuration and make the router the default gateway for the FortiGate unit.
Create New Add a static route to the Static Route list. See “Adding a static route to
the routing table” on page 184.
IP The destination IP addresses of packets that the FortiGate unit
intercepts.
Mask The network masks associated with the IP addresses.
Gateway The IP addresses of the next-hop routers to which intercepted packets
are forwarded.
Device The names of the FortiGate interfaces through which intercepted
packets are received and sent.
Distance The administrative distances associated with each route. The values
represent distances to next-hop routers.
