Chapter 7 WAN Table 38 Network > WAN > Internet Connection: Ethernet Encapsulation (continued) LABEL DESCRIPTION First DNS Server Second DNS Server Select From ISP if your ISP dynamically assigns DNS server information (and the NBG418N'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 primary and secondary DNS server's IP address in the fields to the right. WAN MAC Address The MAC address section allows users to configure the WAN port's MAC address by either using the NBG-418N'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. Clone the computer's MAC address - MAC Address Select this option to clone the MAC address of the computer (displaying in the screen) from which you are configuring the NBG-418N. Once it is successfully configured, the address will be copied to the rom file. It will not change unless you change the setting or upload a different ROM file. Set WAN MAC Address Select this option and enter the MAC address you want to use. Apply Click Apply to save your changes back to the NBG-418N. Reset Click Reset to begin configuring this screen afresh. 7.3.2 PPPoE Encapsulation The NBG-418N 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-418N (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG-418N does that part of the task. Furthermore, with NAT, all of the LANs' computers will have access. 88 NBG-418N User's Guide

7.3.2
PPPoE Encapsulation
The NBG-418N 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-418N (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the NBG-418N does that part of
the task. Furthermore, with NAT, all of the LANs’ computers will have access.

The MAC address section allows users to configure the WAN port's MAC address by either
using the NBG-418N’s MAC address, copying the MAC address from a computer on your
LAN or manually entering a MAC address.
