The items in the IPX Filters and Filter Sets screen are grouped into four areas:
■
IPX packet filters
■
IPX packet filter sets
■
IPX SAP filters
■
IPX SAP filter sets
The following sections explain the items in each of these areas.
IPX packet filters
For each IPX packet filter, you can configure a set of parameters to match on the source or destination
attributes of IPX data packets coming from or going to the WAN.
Viewing and modifying packet filters
To display a view-only table of IPX packet filters, select Show/Change IPX Packet Filters in the IPX Filters and
Filter Sets screen.
To modify any of the filters in the table, note the desired filter and press Return to go to the Change Packet Filter
screen. The parameters in this screen are the same as the ones in the Add Packet Filter screen (see the next
section).
Adding a packet filter
To add a new IPX packet filter, select Add IPX Packet Filter in the IPX Filters and Filter Sets screen and press
Return to go to the Add Packet Filter screen.
By default, the filter’s socket numbers and network and node addresses are null (all zeros). This sets the filter
to match on any IPX data packet. You should configure the filter using criteria that meet your security needs.
