Nortel Networks NN46110-602 manual IPX client

Appendix D Configuring for interoperability 223

Network addresses form the basis of the IPX internetwork addressing scheme for sending packets between network segments. Every network segment of an internetwork is assigned a unique network address by which routers forward packets to their final destination network. On the VPN Router, all public interfaces are treated as a single network segment with a unique network address. A network address in the NetWare environment consists of eight hexadecimal characters. In the example 0xnnnnnnnn, 0x indicates that this is a hexadecimal number, and n is any hexadecimal character.

Socket numbers are the basis for an IPX intranode address (the address of an individual entity within a node). They allow a process (for example, IPX Routing Information Protocol [RIP] and Service Access Points [SAP]) to distinguish itself to IPX. To communicate on the network, the process must request a socket number. Any packets IPX receives addressed to that socket are then passed on to the process within the node.

The VPN Router uses IPX RIP and SAP to dynamically learn and advertise IPX routes and services. The VPN Router assigns IPX addresses to tunneled clients; remote users cannot configure the IPX tunnel address for their systems.

The VPN Router does not forward IPX packets from a private nontunneled LAN to another private nontunneled LAN, nor does it propagate routing or server tables from a private nontunneled LAN to another private nontunneled LAN.

IPX client

On the PPTP client (for example, Microsoft Dial-Up Networking), you must enable the dial-up networking IPX option. When you enable IPX, you can tunnel using IPX, IP, or IPX and IP according to the dial-up networking selections.
