CHAPTER 4

WAN

This chapter describes how to configure WAN settings.

4.1 Overview

A WAN (Wide Area Network) is an outside connection to another network or the Internet. Use the WAN screens to change your Prestige's WAN settings, click Configuration and WAN in the navigation panel.

4.1.1 Encapsulation Types

This section describes the various encapsulation (Internet connection) types the Prestige offers.

4.1.1.1 RFC 1483

RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer to the RFC for more detailed information.

In addition, the Prestige supports two RFC 1483 methods; routed or bridged. In RFC 1483 Bridged, the Prestige sends the packets based on the MAC address information. That is, the Prestige bridges the packets. In RFC 1483 Routed, the Prestige sends the packets based on the IP address. That is, the Prestige routes the packets. Refer to the RFC for more information.

4.1.1.2 PPPoE

The Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard (RFC 2516) specifying how a computer interacts with a broadband modem (DSL, cable, wireless, etc.) connection. PPPoE 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). PPPoE provides a login and authentication method that the existing Microsoft Dial-Up Networking software can activate, nd therefore requires no new learning or procedures for Windows users. 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.
