IPX Packet Filter Rule Examples
Drop all packets where the source network number is greater than or equal to
1000 and permit all other packets:
deny srcnet >= 1000 permit type = ALL
Drop all packets from a specific IPX network and node and permit all other packets:
deny srcnet = FAB4 srcnode = 0.0.A5.0.0.1 permit
Drop all packets where the source socket is a diagnostic packet, log the denial and permit all other packets through:
deny srcskt = DIAG log permit
IPX Route Filter Rules
To access an editor window for IPX Route filters, open the Main IPX Filtering Dialog Box (under Global/Filtering/IPX Filtering) and then select the Route Filters button.
Route filtering rules are applied globally in the device and are not associated with any interface. However, they can be restricted to an interface using the “from” or “to” modifiers in the rule.
A device does not reorder rule sets as they have been specified before they are applied. They are applied in the order they were written. When multiple filter sets are selected with CompatiView, the filter sets will be concatenated in the device from first to last (top to bottom on screen).
Any IPX network not explicitly allowed by the rules will not be included in the routing table on input or in the routing update on output. To allow all other network numbers not filtered, the last rule must be:
permit network = ALL
Rules that have been specified using CompatiView may be edited or exam- ined through the command line interface, and
Rule sets that have been created with the IPX Route Filter Editor Window must be selected using the
