Remote Access Server

IPX

To configure an IPX-based remote access client with IPXCP, the remote access server allocates an IPX network number and an IPX node number. The network number allocation behavior is configured from the IPX tab on the properties of a remote access router in the Routing and Remote Access snap-in. The main capabilities of IPX configuration are:

IPX network numbers for remote access clients can be automatically allocated or specified as a range by the network administrator. For automatically allocated IPX network numbers, the remote access server ensures that the IPX network number is not being used on the IPX internetwork by sending a RIP GetLocalTarget packet on its LAN interfaces. If there is a response to the RIP GetLocalTarget, then the IPX network number is in use and another IPX network number is chosen.
The same IPX network number can be assigned to all remote access clients.
Specific IPX node numbers can be requested by remote access clients.

You can set the first IPX node number as a 12-digit hexadecimal number to be allocated to IPX remote access clients.To do so, add the FirstWanNode (REG_SZ) registry entry to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess \Parameters\Ipx

And enter the desired IPX node number in the value of the entry.

Subsequent IPX clients are assigned incrementally increasing node numbers. If this registry entry does not appear in the registry, a random IPX node number, in the form 0x2E-xx-xx-xx-xx-xx (where you specify each x digit), is assigned when the remote access client does not request a specific IPX node number.
