Explanation
Matches the packet's destination IP address. To test 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.
Matches the TCP or UDP destination port. 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 A13-5.
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 A13-5.

132.245.33.0/24 appears as the destination address.)
