Novell IPX Routing
Source Socket
IPX packets from a specific source socket can be discarded. The most common
IPX sockets (
NCP
,
NetBios
,
NLSP
and
IPX Ping
) can be selected from a list.
Other sockets can be filtered by selecting
Other
for the
Source Socket
and
then entering the socket number
Value
.
Packet Type
Specific IPX packet types can be filtered. NCP and SPX packets can be selected
from a list. Other packets types can be filtered by selecting
Other
for the
Pack-
et Type
and then entering the socket number
Value
.
IPX Filters Example
Filter requirement
NetWare devices use Diagnostic Request Packets to get information from about
other reachable devices. These packets can be used for testing if a device is reach-
able and gathering configuration information about devices.
Diagnostic Request Packets can be broadcast to all devices and require each de-
vice to respond and can cause WAN links to become saturated. It is therefore
sometimes desirable to eliminate these diagnostics from WAN links, and this can
be done using the IPX data filters implemented in the Intel Express 8100 Router.
Note
IPX ping may be affected by these filters, depending on whether the
implementation of ping in the device which is testing for connectivity,
uses the diagnostics responder.
