Enter the settings that your service provider gave you.

If your service provider gave you only one user name and password, the service provider 
most likely supports dual stack PPPoE (a single ppp session). If the service provider gave

PPP session. 

To use separate PPP sessions (the default setting), leave the Use the same Login 
information as IPv4 PPPoE check box cleared and complete the PPP Login and 
Password fields. 

To use a single PPP session to establish the IPv4 and IPv6 Internet connection, 
select the Use the same Login information as IPv4 PPPoE check box.

is acquired, the field displays Not Available.

the field displays Not Available.
