6Set Device #1 to the FortiGate interface or VLAN subinterface through which to route traffic to connect to Gateway #1.
You can select the name of an interface, VLAN subinterface, or Auto (the default). If you select the name of an interface or VLAN subinterface the traffic is routed to that interface. If you select Auto the system selects the interface according to the following rules:
•If the Gateway #1 IP address is on the same subnet as a FortiGate interface or VLAN subinterface, the system sends the traffic to that interface.
•If the Gateway #1 IP address is not on the same subnet as a FortiGate interface or VLAN subinterface, the system routes the traffic to the external interface, using the default route.
You can use Device #1 to send packets to an interface that is on a different subnet than the destination IP address of the packets without routing them using the default route.
7Set Device #2 to the FortiGate interface or VLAN subinterface through which to route traffic to connect to Gateway #2.
You can select the name of an interface, VLAN subinterface, or Auto (the default). If you select the name of an interface or VLAN subinterface the traffic is routed to that interface. If you select Auto the system selects the interface according to the following rules:
•If the Gateway #2 IP address is on the same subnet as a FortiGate interface or VLAN subinterface, the system sends the traffic to that interface.
•If the Gateway #2 IP address is not on the same subnet as a FortiGate interface or VLAN subinterface, the system routes the traffic to the external interface, using the default route.
You can use Device #2 to send packets to an interface that is on a different subnet than the destination IP address of the packets without routing them using the default route.
8Select OK to save the route.
Note: Any two routes in the routing table must differ by something other than just the gateway to be simultaneously active. If two routes added to the routing table are identical except for their gateway IP addresses, only the route closer to the top of the routing table can be active.
Note: Arrange routes in the routing table from more specific to more general. For information about arranging routes in the routing table, see “Configuring the routing table”.
Adding routes in Transparent mode
Use the following procedure to add routes when operating the FortiGate unit in
Transparent mode.
To add a route in Transparent mode
1Go to System > Network > Routing.
2Select New.
3Enter the Destination IP address and Netmask for the route.
4Enter the Gateway IP address for the route.
