Encapsulation
The PPPoE choice is for a dial-up connection using PPPoE. The router supports 
PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard (RFC 
2516) specifying how a personal computer (PC) interacts with a broadband modem (i.e. 
xDSL, cable, wireless, etc.) connection. Operationally, PPPoE saves significant effort 
for both the end user and ISP/carrier, as it requires no specific configuration of the 
broadband modem at the customer site. By implementing PPPoE directly on the router 
rather than individual computers, the computers on the LAN do not need PPPoE 
software installed, since the router does that part of the task. Further, with NAT, all of 
the LAN's computers will have access. 
Service Name
Type the PPPoE service name provided to you. PPPoE uses a service name to identify 
and reach the PPPoE server.
