Keyword Value Explanation
src_port {pnum | sname | * | -1} Matches the TCP or UDP
source port number. Specify
the port as a decimal number
(pnum) from 1 – 65535 or as a
standard service name
(sname), such as finger, ftp,
nfs, rlogin, smtp, telnet, or
tftp. Specifying –1 or “*”
matches all port numbers. For
a list of service names and
their corresponding port
numbers, see
Table A-13 .
src_address {ip_addr[/n] | * | -1} Matches the packet’s source IP
address. To match only the
non-host portion of the
address, enter /n after the
address, where n is the number
of bits in the non-host portion
of the subnet mask for this
address. For example,
132.245.33.0/24 denotes a
mask of 255.255.255.0, which
matches destination addresses
on network 132.245.33.0. (If
you list the filter,
132.245.33.0/24 appears as the
destination address.)
To match all addresses, enter –
1 or “*” instead of an address.
