• 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 cut 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 Option: 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.
