4 Complete the addressing configuration.
• For manual addressing, enter the IP address and netmask for the interface.
• For DHCP addressing, select DHCP and any required settings.
• For PPPoE addressing, select PPPoE, and enter the username and password and
any other required settings.
For information about how to configure these and other interface settings, see the
FortiGate online help or the FortiGate Administration Guide.
5 Select OK.
6 Repeat this procedure for each interface.
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.
To configure DNS server settings
1 Go to System > Network > DNS.

3 Enter the IP address of the secondary DNS server.
4 Select OK.
To add 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.
1 Go to System > 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.
4 Set Destination IP to 0.0.0.0.
5 Set Mask to 0.0.0.0.
6 Set Gateway to the default gateway IP address.
