RFC 2516 PPPoE
Some DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) to establish Internet connections. If
you are connected to the Internet through a DSL line, check with your ISP to see if they use PPPoE. If they
do, you will have to enable PPPoE.
• Service Name. Enter the name of your PPPoE service in the field.
• User Name and Password. Enter the User Name and Password provided by your ISP.
• Connect on Demand: Max Idle Time. You can configure the Gateway to disconnect the Internet
connection after it has been inactive for a specified period of time (Max Idle Time). If your Internet
connection has been terminated due to inactivity, Connect on Demand enables the Gateway to
automatically re-establish your connection as soon as you attempt to access the Internet again. If you
wish to activate Connect on Demand, click the radio button. In the Max Idle Time field, enter the
number of minutes you want to have elapsed before your Internet connection terminates.
• Keep Alive: Redial Period. If you select this option, the Gateway will periodically check your Internet
connection. If you are disconnected, then the Gateway will automatically re-establish your connection.
To use this option, click the radio button next to Keep Alive. In the Redial Period field, you specify how
often you want the Gateway to check the Internet connection. The default Redial Period is 30 seconds.
