The MAX links a Local Area Network (LAN) to a Wide Area Network (WAN). The LAN
might comprise a few workstations, a large n umber of workstations and servers, or any number
of interconnected networks. WAN connections provid e lin ks between the LAN and virtually
any site or network.

The MAX provides multiple interfaces for your use in implementing your configuration.
Considerations for development of your WAN configuration include the number of remote
users who need access to your LAN, the types of telecommunications lines and services your
carrier can provide, and the spec ific MAX mo del y ou hav e p urch ased. WAN connections hav e
traditionally been either physically dedicated (nailed) from end to end or dial-up (switched).
Frame Relay, which provides the benefits of nailed connections but with greater flexibility, is
becoming increasingly popular. X.25 networks are predominant in Europe.

Although the MAX has a large number of features, you might only have to configure a few of
them, depending on what you want the MAX to do. Almost all applications require
configuration of IP routing. You can use R outin g In formation Protocol (RIP) or the newer

Open Shortest Path First (OSPF) protocol, which addresses many of RIP’s limitations. If you
have Novell Netware clients and servers, you can configure the MAX for Internetwork Packet

Introduction

eXchange (IPX) routing. Similarly, you can configure it for AppleTalk routing. If you need to
use a protocol that cannot be routed, the MAX supports transparent bridging as an alternative.

If you need to send data-intensive information to multiple users simultaneously, you can
significantly reduce traffic flow by setting up your network to support multicast forwarding. If
you have many remote clients who need secure connections to the home network, a tunneling
protocol, such as ATMP, PPTP, or L2TP, can provide virtual private connections over a public
network.

Y o u can define filters to cu stomize the way the MAX handles individua l packets of data. If yo u
do not implement dynamic filtering by means of a firewall such as an Ascend SecureConnect
firewall, you should probably define a filter on the MAX to provide rudimentary security. You
can also define filters to prevent unnecessary connections and to clear idle connections.
