Possible keywords are server, network, host, and socket.
server
Compare the server name of an advertised service to the server
name of the packet filter.
< permit | deny> server <server name>
network
Compare the IPX network number of the advertised service to
the network IPX address. The IPX network number must be in
hexadecimal format.
< permit | deny> network <IPX network number>
host
The IPX node address of the service is compared to the host IPX
node address specified in the packet filter. The IPX address
must be in hexadecimal format.
< permit | deny> host <IPX network address>

Compare the server’s IPX socket number to the one given in the
filter. You must specify the type of the comparison. Valid
comparisons are: less than (lt), equal (eq), or greater than (gt).
< permit | deny> socket <lt | gt | eq> <IPX network address>
