8.3.2 PPPoE Encapsulation
The NBG-416N 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 NBG-416N (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG-416N does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.
