13.4.2 PPPoE Encapsulation

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,
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 (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.
Chapter 13 WAN
DESCRIPTION
Select From ISP if your ISP dynamically assigns DNS server information (and the NBG's
WAN IP address). The field to the right displays the (read-only) DNS server IP address that
the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS server's IP
address in the field to the right. If you chose User-Defined, but leave the IP address set to
0.0.0.0, User-Defined changes to None after you click Apply. If you set a second choice
to User-Defined, and enter the same IP address, the second User-Defined changes to
None after you click Apply.
Select None if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
The MAC address section allows users to configure the WAN port's MAC address by either
using the NBG's MAC address, copying the MAC address from a computer on your LAN or
manually entering a MAC address.
Select Factory default to use the factory assigned default MAC Address.
Select Clone the computer's MAC address - IP Address and enter the IP address of the
computer on the LAN whose MAC you are cloning.
Select this option and enter the MAC address you want to use.
Click Apply to save your changes back to the NBG.
Click Reset to begin configuring this screen afresh.
