NBG6616 User’s Guide

Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF 
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with 
a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data 
networks.

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

One of the benefits of PPPoE is the ability to let end users 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 specific users.

Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it 
requires no specific configuration of the broadband modem at the subscriber's 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 LAN's computers will have Internet access.
