NBG4615 User’s Guide

The NBG4615 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 NBG4615 (rather than individual 
computers), the computers on the LAN do not need PPPoE software installed, 
since the NBG4615 does that part of the task. Furthermore, with NAT, all of the 
LANs’ computers will have access.
