Defining Filters and Firewalls
Working with predefined call filters
6-22 Preliminary January 30, 1998 Pipeline User’s Guide
NetWare servers broadcast SAP packets every 60 seconds to make sure that all
routers and bridges know about available services. To prevent these packets from
keeping a connection up unnecessarily, apply the predefined NetWare Call filter
in the Session Options submenu of a Connection or Answer profile in which IPX
routing is configured.
The predefined NetWare Call filter contains six Output filters, which identify
outbound SAP packets and prevent them from resetting the idle timer or initiating
a call.
