Defining Static Filters
Defining IPX filters
can change each time they load. A socket number of all 1s (FF:FF) matches any socket on the
specified server.
When you specify a NetWare socket number, you must also indicate how to compare the
socket number in a packet to the specification in the filter. The Src Socket Cmp parameter
specifies the method of comparison for the source socket number. You can specify that the
filter matches the packet if the packet’s source socket number is Less (less than), Eql (equal
to), Gtr (greater than), or Neq (not equal to) the source socket number specified in the filter.
The Dst Socket Cmp parameter specifies the method of comparison for the destination socket
number. You can specify that the filter matches the packet if the packet’s destination socket
number is Less (less than), Eql (equal to), Gtr (greater than), or Neq (not equal to) the
destination socket number specified in the filter.
Example of an outbound IPX filter
When the following sample IPX filter is applied as a data filter to a WAN interface, it causes
the MAX unit to drop all outbound IPX packets that have a destination IPX network address of
00003823, regardless of the destination IPX node or socket number in the packets. All other
packets are forwarded.

Example of an inbound IPX filter
When the following sample IPX filter is applied as a data filter to a WAN interface, it causes
the MAX unit to drop all inbound IPX packets received from a specific source. In this
example, the filter causes the MAX unit to drop packets from source IPX network address
00000005:00abcde12345 and source socket number 4002. All other packets are forwarded.
