To access this dialog box, select VPN/IPX Routing in the Device View.

This set of radio buttons controls how IPX packets are handled for this 
interface.

•

If set to IPX Routing, then IPX packets received on this interface are 
routed to the correct interface on the device.

•

If set to IPX Bridging, then any IPX packets received on this interface 
are forwarded to the device’s internal bridge. This setting makes this 
interface a member of the “IPX Bridge Group” for this device.

v Note:  The IPX Bridging radio button will be grayed out unless bridging 
has been turned on globally for the device using the Main Bridging Configu-
ration Dialog Box (under Global/Bridging) and locally on this interface 
using the VPN-Bridging Dialog Box (under VPN/Bridging). 

•

If it is set to IPX Off, then any IPX packets received on this interface are 
discarded.

This checkbox determines whether the VPN port will have an IPX network 
number associated with it.

VPN tunnels are essentially point-to-point links. These links do not generally 
require a network number because all traffic sent from one end is, by defini-
tion, destined for the other end. However, you may wish to assign an address 
for network tracking purposes.

This IPX Network Number is an eight-digit hexadecimal number that 
uniquely identifies the network segment(s) connected to this interface. Values 
range from 1 to FFFFFFFE.

v Note:  Accidental selection of an IPX network number which is already in 
use on another network segment may cause hard-to-diagnose problems. You 
should carefully track which IPX network numbers are in use, and where they 
are used.

VPN links which are configured to provide “dial-on-demand” service will 
bring a connection up (i.e. dial the other end) when there are network packets 
which must be transferred over the link. Once a dial-on-demand connection 
is up, network traffic passing across the link causes the inactivity timer for the 
link to be reset, keeping the connection up.
