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.
NBG4615 User's Guide
DESCRIPTION
Select this option If the ISP assigned a fixed IP address.
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
Enter the IP Subnet Mask in this field.
Enter a Gateway IP Address (if your ISP gave you one) in this field.
Select From ISP if your ISP dynamically assigns DNS server information (and
the NBG4615'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 NBG4615'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 NBG4615.
Click Cancel to begin configuring this screen afresh.
