Novell IPX Routing
Filter criteria
Each filter in the Intel Express 8100 Router can be setup to pass or discard IPX
packets based on the following criteria:
Note
All the filter criteria defined is used.
Destination Network Addresses
IPX data traffic addressed to a single destination network address, or range of
network addresses specified by the
Destination Network Address
and
Destination Network Mask
parameters can be filtered.
When the
Destination Network Mask
parameter is set to FFFFFFFF, pack-
ets addressed to the single
Destination Network Address
specified will be
filtered.
Filtering of packets to destination network addresses is disabled if a
Destina-
tion Network Address
of 00000000 with a
Destination Network Mask
of FFFFFFFF is defined (default values). For other values of the
Destination
Network Mask
, data packets addressed to a range of network addresses will be
filtered.
For example, with a
Network Address
of ABC00000 and a
Network Mask
:
FFF00000, service information will be filtered from/to all servers on the net-
works beginning with ABC.
Destination Node Address
IPX packets addressed to a single device (node) can be filtered. A
Destination
Node Address
of 000000000000 disables filtering on the destination node ad-
dress.
Destination Socket
IPX packets addresses to specific sockets 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
Destination Socket
and then entering the socket number
Value
.
Source Network Addresses
IPX data traffic from a single source network address, or range of network ad-
dresses specified by the
Source Network Address
and
Source Network
Mask
parameters can be filtered.
When the
Source Network Mask
parameter is set to FFFFFFFF, packets from
the single
Source Network Address
specified will be filtered.
Filtering of packets from source network addresses is disabled if a
Source Net-
work Address
of 00000000 with a
Source Network Mask
of FFFFFFFF is
defined (default values). For other values of the
Source Network Mask
, data
packets from a range of network addresses will be filtered.
For example, with a
Network Address
of ABC00000 and a
Network Mask
:
FFF00000, service information will be filtered from/to all servers on the net-
works beginning with ABC.
Source Node Address
IPX packets from a single device (node) can be filtered. A
Source Node Ad-
dress
of 000000000000 disables filtering on the source node address.
