Adding DNS server IP addresses

Several FortiGate functions, including sending email alerts and URL blocking, use DNS. Use the following procedure to add the IP addresses of the DNS servers that your FortiGate unit can connect to. DNS server IP addresses are usually supplied by your ISP.

To add DNS server IP addresses

1Go to System > Network > DNS.

2Change the primary and secondary DNS server IP addresses as required.

3Select Apply to save the changes.

Configuring routing

This section describes how to configure FortiGate routing. You can configure routing to add static routes from the FortiGate unit to local routers. Using policy routing you can increase the flexibility of FortiGate routing to support more advanced routing functions.

You can also use routing to create a multiple Internet connection configuration that supports redundancy and load sharing between the two Internet connections.

This section describes:

Adding a default route

You can add a default route for network traffic leaving the external interface.

To add a default route

1Go to System > Network > Routing Table.

2Select New to add a new route.

3Set the Source IP and Netmask to 0.0.0.0.

4Set the Destination IP and Netmask to 0.0.0.0.

5Set Gateway 1 to the IP address of the routing gateway that routes traffic to the Internet.

6Select OK to save the default route.

Note: Only one default route can be active at a time. If two default routes are added to the routing table, only the default route closest to the top of the routing table is active.
