Access

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.

(Network

Address

Translation)

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

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

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

public IP address used on the Internet).
Select this checkbox to enable NAT.
