Chapter 5: Linking two networks

for the LAN of the head office for the LAN of the branch office for the higher-level WAN

The IPX network numbers in the head and branch offices are specified to the respective remote sides.

IPX internal net:

00020002

WAN

IPX network no.:

00000009

VPN or ISDN

connection

(0123) 123456

LAN of the head office

IPX network no.: 00000001

Binding: Ethernet_II

EN

(0789) 654321

LAN of the branch office

IPX network no.: 00000002

Binding: Ethernet_II

The three required network numbers are designated as “External Network Numbers” by the IPX conventions. Like IP network addresses, the apply to an entire LAN segment. On the other hand, internal IPX numbers are used to address specific Novell servers in the LAN. All three specified network num- bers must be distinct from one another and from all used internal IPX network numbers.

In addition, it may be necessary to enter the frame type (“binding”).

Specifying the IPX network number and binding used is not necessary if the remote network also contains a Novell server. It is only necessary to enter the network number for the WAN manually in this case.

5.1.4Settings for NetBIOS routing

NetBIOS routing can be set up quickly: All that is required in addition to the information for the TCP/IP protocol used is the name of a Windows workgroup from in the router's own LAN.
