To configure an interface for PPPoE
Use this procedure to configure any FortiGate interface to use PPPoE. See
on page 51 for information on PPPoE settings.
1 Go to System > Network > Interface.
2 Choose an interface and select Edit.
3 In the Addressing Mode section, select PPPoE.
4 Enter your PPPoE account User Name and Password.
5 Enter an Unnumbered IP if required by your PPPoE service.
6 Set the Initial Disc Timeout and Initial PADT Timeout if supported by your ISP.
7 Select the Retrieve default gateway from server check box if you want the FortiGate
unit to obtain a default gateway IP address from the PPPoE server.
8 Select the Override Internal DNS check box if you want the FortiGate unit to obtain a
DNS server IP address from the PPPoE server.
9 Select the Connect to Server check box if you want the FortiGate unit to connect to
the PPPoE server.
Select Apply.
The FortiGate unit attempts to contact the PPPoE server from the interface to set the
IP address, netmask, and optionally default gateway IP address and DNS server IP
addresses.
11 Select Status to refresh the addressing mode status message.
Select OK.
To add a secondary IP address
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.
From the FortiGate CLI, enter the following commands:
config system interface
edit <intf_str>
config secondaryip
edit 0
set ip <second_ip> <netmask_ip>
Optionally, you can also configure management access and add a ping server to the
secondary IP address:
set allowaccess ping https ssh snmp http telnet
set gwdetect enable
Save the changes:
