NBG6616 User’s Guide

The NBG6616 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard 
(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, 
cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using 
PPPoE.

For the service provider, PPPoE offers an access and authentication method that works with existing 
access control systems (for example Radius).

One of the benefits of PPPoE is the ability to let you access one of multiple network services, a 
function known as dynamic service selection. This enables the service provider to easily create and 
offer new IP services for individuals.

Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no 
specific configuration of the broadband modem at the customer site.

By implementing PPPoE directly on the NBG6616 (rather than individual computers), the computers 
on the LAN do not need PPPoE software installed, since the NBG6616 does that part of the task. 
Furthermore, with NAT, all of the LANs’ computers will have access.
