Encapsulation

The PPPoE choice is for a dial-up connection using PPPoE. The router 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

 

(i.e. DSL, cable, wireless, etc.) connection. Operationally, PPPoE saves significant

 

effort for both the end user and ISP/carrier, as it requires no specific configuration of

 

the broadband modem at the customer site. By implementing PPPoE directly on the

 

router rather than individual computers, the computers on the LAN do not need

 

PPPoE software installed, since the router does that part of the task. Further, with

 

NAT, all of the LAN's computers will have access.

Service Name

Type the PPPoE service name provided to you. PPPoE uses a service name to

 

identify and reach the PPPoE server.

Enable NAT

Network Address Translation (NAT) allows the translation of an Internet protocol

(Network

address used within one network (for example a private IP address used in a local

Address

network) to a different IP address known within another network (for example a

Translation)

public IP address used on the Internet).

 

Select this checkbox to enable NAT.

 

For more information about NAT see Chapter 22 on page 370.
