IPX Description

Introduction

The purpose of IPX is to allow Novell NetWare clients to dial in to (or directly attach to) the network access server via asynchronous lines. Each remotely connected Novell client looks and acts as if it was directly connected to the LAN.

The network access software provides PPP/IPXCP as the underlying data link on the asynchronous lines. This allows multiprotocol support (IP/IPX/AppleTalk) over the same asynchronous lines simultaneously.

Access Server Configuration

The access server can be set up to provide access for remote PC users to dial in over standard telephone lines to establish an IPX connection to a Novell network. The remote PC can access network resources such as file servers, printers, and electronic mail. Once connected, the PC becomes a remote node on the network. The access server facilitates IPX client-server communications between PC and NetWare file servers over the standard telephone line.

The remote node service provides the same functions and features to remote PCs as locally connected LAN users. The main difference between the remote node connection and a local connection using Ethernet is the data transfer speed. However, dial-in connections that use high-speed modems provide excellent performance.

The PC gains access to the IPX network through the access server by using any third- party remote node access software that supports the point-to-point protocol (PPP) for IPX. The remote access software must also facilitate the use of Novell NetWare workstation software, which is used to communicate with the Novell network over the dial-up connection.

By default, the access server will simultaneously communicate with all four frame types on the LAN: Ethernet II, 802.2 SAP, 802.2 SNAP, and Novell 802.3. When IPX is enabled on the access server, the network addresses for all four types will automatically be learned.
