Configuring an interface for PPPoE

Adding a secondary IP address to an interface

96
Use the following procedure to configure any FortiGate interface to use PPPoE.
If you configure the interface to use PPPoE, the FortiGate unit automatically
broadcasts a PPPoE request. You can disable connect to server if you are configuring
the FortiGate unit offline and you do not want the FortiGate unit to send the PPPoE
request.
By default, the FortiGate unit also retrieves a default gateway IP address and DNS
server IP addresses from the PPPoE server. You can disable the option Retrieve
default gateway and DNS from server if you do not want the PPPoE server to
configure these FortiGate settings.
To configure an interface for PPPoE
1 Go to System > Network > Interface.
2 Choose an interface and select Modify
3 In the Addressing Mode section, select PPPoE.
4 Enter your PPPoE account User Name and Password.
5 Clear the Retrieve default gateway and DNS from server check box if you do not want
the FortiGate unit to obtain a default gateway IP address and DNS server IP
addresses from the PPPoE server.
By default, this option is enabled.
6 Clear the Connect to Server check box if you do not want the FortiGate unit to connect
to the PPPoE server.
By default, this option is enabled.
7 Select Apply.
The FortiGate unit attempts to contact the PPPoE server from the interface to set the
IP address, netmask, default gateway IP address, and DNS server IP addresses.
8 Select Status: to refresh the addressing mode status message. Possible messages:
initializing No activity
connecting The FortiGate unit is attempting to connect to the DHCP server.
connected The FortiGate unit retrieves an IP address, netmask, and other settings from
the PPPoE server.
failed The FortiGate unit was unable to retrieve an IP address and other
information from the PPPoE server.
9 Select OK.
You can use the CLI to add a secondary IP address to any FortiGate interface. The
secondary IP address cannot be the same as the primary IP address but it can be on
the same subnet.
To add a secondary IP address from the CLI enter the command:
set system interface <intf_str> config secip <second_ip>
<netmask_ip>
