Changing IPX Parameters

The IPX Setup dialog box controls the four frame types and the WAN ports. The advanced tab
enables IPX routing, enables auto learn of Ethernet network numbers, and specifies the distributed
name of the MultiFRAD.

The RIP and SAP default timers should not have to be changed for most applications. Disabling IPX
and SPX Watchdog Spoofing in the Bandwidth Optimization group has proven effective under certain
circumstances with Citrix clients.

The IPX WAN Setup dialog box lets you to enable or disable IPX routing on the WAN port, change
the network number for the WAN port, enable or disable NetBIOS, change the default RIP and SAP
timers, and optimize the bandwidth. If the  WAN port is configured for frame relay, this dialog box lets
you to add logical WANs. How the WAN port is configured is controlled by the WAN Port Setup dialog
box that you access by clicking the WAN button on the MF200 main menu.
