Initial PPPoE Active Discovery Terminate (PADT) timeout in seconds.

for this number of seconds. PADT must be supported by your ISP. Set
initial PADT timeout to 0 to disable.
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.
Enable Retrieve default gateway from server to retrieve a default
gateway IP address from a PPPoE server. The default gateway is
added to the static routing table.
Enable Override internal DNS to replace the DNS server IP addresses
on the System 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 when you select OK or Apply.
Disable this option if you are configuring the interface offline.
Configuring Dynamic DNS service for an interface
When the FortiGate unit has a static domain name and a dynamic public IP
address, you can use a DDNS service to update Internet DNS servers when the
IP address for the domain changes.
Dynamic DNS is available only in NAT/Route mode.
Go to System > Network > Interface. Select Create New or select the Edit icon
of an existing interface. Enable DDNS, just below the Addressing mode section,
and configure the DDNS service using the information they have provided to you.
