Select User-Definedif 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-Definedchanges to None after you

 

click Apply. If you set a second choice to User-Defined, and enter the same IP

 

address, the second User-Definedchanges 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 NBG4615’s MAC address, copying the MAC address from a

 

computer on your LAN or manually entering a MAC address.

17.4.2 PPPoE Encapsulation

The NBG4615 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.
