PPP Information (This is available only when you select PPPoE or PPPoA in the Mode field.)
PPP User Name Enter the user name exactly as your ISP assigned. If assigned a name in the form
user@domain where domain identifies a service name, then enter both components exactly

PPP Trigger
Type
Select when to have the VMG establish the PPP connection.
Auto Connect - select this to not let the connection time out.
Connect on Demand - select this to automatically bring up the connection when the VMG
receives packets destined for the Internet.
Manual - select this if you want to manually trigger the connection up.
Authentication
Method
Select an authentication protocol for outgoing connection requests through this WAN
interface.
PAP - Password Authentication Protocol (PAP) authentication sends user name and
password in clear text without using encryption. Select this if your VMG accepts PAP only.
CHAP - Challenge Handshake Authentication Protocol (CHAP) provides authentication
through a shared secret key and uses a three way handshake. Select this if your VMG
accepts CHAP only.
MSCHAP - Microsoft CHAP provides authentication through a shared secret key and uses a
three way handshake. It provides improved usability with Microsoft products. Select this if
your VMG accepts MSCHAP only.
AUTO - Select this if your VMG accepts either PAP, CHAP, or MSCHAP authentication
method.
Idle Timeout This value specifies the time in minutes that elapses before the router automatically
disconnects from the PPPoE server.
This field is not configurable if you select Auto Connect in the PPP Trigger Type field.
PPPoE Service
Name
Enter the name of your PPPoE service here.
PPPoE
Passthrough
This field is available when you select PPPoE encapsulation.
In addition to the VMG’s built-in PPPoE client, you can enable PPPoE pass through to allow up
to ten hosts on the LAN to use PPPoE client software on their computers to connect to the
ISP via the VMG. Each host can have a separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for application where NAT is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use PPPoE client
software on their computers to connect to the ISP.
IP Address (This is available only when you select IPv4 Only or IPv6/IPv4 DualStack in the IPv6/IPv4
Mode field.)
