13.4.2 PPPo E Enc a psula tio n
The NBG 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, WiFi, etc.)
connection. The
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 (rather than individual computers), the computers on the
LAN do not need PPPoE software installed, since the NBG does that part of the task. Furthermore, with
NAT, all of the LANs' computers will have access.
