Configuring the routing table

The routing table shows the destination IP address and mask of each route that you

add, as well as the gateways and devices added to the route. The routing table also

displays the gateway connection status. A green check mark indicates that the

FortiGate unit has used the ping server and dead gateway detection to determine that

it can connect to the gateway. A red X means that a connection cannot be established.

A blue question mark means that the connection status is unknown. For more

information, see “Adding a ping server to an interface” on page 146.

The FortiGate unit assigns routes using a best match algorithm based on the

destination address of the packet and the destination address of the route. To select a

route for a packet, the FortiGate unit searches the routing table for a route that best

matches the destination address of the packet. If a match is not found, the FortiGate

unit routes the packet using the default route.

To configure the routing table

1 Go to System > Network > Routing Table.

2 Choose the route that you want to move and select Move to to change its order in

the routing table.

3 Type a number in the Move to field to specify where in the routing table to move the

route and select OK.

4 Select Delete to delete a route from the routing table.
