The same parameters are also available in the Output Filters subprofile. If you set the
parameters in an input filter, only inbound packets are examined. If you set them in an output
filter, only outbound packets are examined.
Filtering by source or destination address
The network address and node address parameters are designed to work together to specify a
source or destination NetWare server. A full IPX network address uses the following format:
network-number:node-number
The Src Net Adrs and Dst Net Adrs parameters specify the network-number portion of the
address. The network number is a unique 8-byte hexadecimal number that is common to all
hosts on a particular LAN. NetWare servers have an internal network number that is the
destination network address for file read/write requests. (If you are not familiar with internal
network numbers, see your NetWare documentation for details.)
The Src Node Adrs and Dst Node Adrs parameters specify the node-number portion of the
address. The node number is a 12-byte hexadecimal number that is unique to each node on a
LAN. Each filter that specifies an IPX network number should also specify the corresponding
node number. (For example, if you specify the Src Net Adrs in a filter, you should also specify
the Src Node Adrs.)
Typically, a NetWare server address has the node number 1 (00:00:00:00:00:01) on the server’s
internal network. A node number of all 1s (FF:FF:FF:FF:FF:FF) matches all nodes on a LAN.
Filtering by socket number
NetWare servers use a particular socket number for each service. For example, NetWare file
service typically uses socket 0451 (04:51). Some services use dynamic socket numbers, which
Parameter Specifies
Src Network Adrs Network Number portion of the source IPX address.
Dst Network Adrs Network Number portion of the destination IPX address.
Src Node Adrs Node Number portion of the source IPX address.
Dst Node Adrs Node Number portion of the destination IPX address.
Src Socket # Source socket number.
Src Socket Cmp Type of comparison to perform against 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.
Dest Socket # Destination socket number.
Dst Socket Cmp Type of comparison to perform against the destination 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.
