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 NBG6716 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6716 does that part of the task.

10.4.2
PPPoE Encapsulation
The NBG6716 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 NBG6716 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6716 does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.

Third DNS Server
Select
Obtained From ISP
if your ISP dynamically assigns DNS server information
(and the NBG6716'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

. 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.
WAN MAC Address
The MAC address section allows users to configure the WAN port's MAC address by
either using the NBG6716’s MAC address, copying the MAC address from a computer on
your LAN or manually entering a MAC address.
Factory default
Select
Factory default
to use the factory assigned default MAC Address.
