9.4.2 PPPoE Encapsulation

The NBG7815 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, and so
on) 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 NBG7815 (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the NBG7815 does that part of the task.
Furthermore, with NAT, all of the LANs' computers will have access.

DESCRIPTION
Select User-Defined and enter the IPv6 DNS server address assigned by the ISP to have the
NBG7815 use the IPv6 DNS server addresses you configure manually.
Select None if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IPv6 address of a computer in order to access it.
