Configuring the ADSL interface using the CLI
Configure the ADSL interface like any other FortiGate physical network interface.
The information that you need to provide depends on the addressing mode your
ISP requires you to use.
This section shows settings that are unique to the ADSL interface and are not
described in other FortiGate documentation. Many settings that apply to interfaces
generally also apply to the ADSL interface. This section shows only the settings
that you might need to configure to communicate with your ISP. For a complete list
of interface settings, refer to system interface in the FortiGate CLI
Reference.

Distance Enter the administrative distance for the default gateway retrieved from
the PPPoE or PPPoA server. The administrative distance, an integer
from 1-255, specifies the relative priority of a route when there are
multiple routes to the same destination. A lower administrative
distance indicates a more preferred route. The default distance for the
default gateway is 1.
Retrieve default
gateway from
server
Enable Retrieve default gateway from server to retrieve a default
gateway IP address from a PPPoE or PPPoA server. The default
gateway is added to the static routing table.

DNS

on the DNS page with the DNS addresses retrieved from the PPPoE
or PPPoA server.
Connect to server Enable Connect to Server so that the interface automatically attempts
to connect to a PPPoE or PPPoA server. Disable this option if you are
configuring the interface off-line.
