-Select From List—The keyword associated with the source port to match: ftp, ftpdata, http, smtp, snmp, telnet, tftp, www.
Each of these keywords translates into its equivalent port number.
-Match to Port—The IANA port number to match to the source port identified in the datagram header. The port range is 0 to 65535 and includes three different types of ports:
0 to 1023—Well Known Ports
1024 to 49151—Registered Ports
49152 to 65535—Dynamic and/or Private Ports
•Destination IP Address—Requires a packet's destination IP address to match the address listed here. Enter an IP address in the appropriate field to apply this criteria.
•Wild Card Mask—The destination IP address wildcard mask.
The wildcard mask determines which bits are used and which bits are ignored. A wildcard mask of 255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all bits are important. This field is required when Source IP Address is selected.
A wildcard mask is basically the inverse of a subnet mask. For example, to match the criteria to a single host address, use a wildcard mask of 0.0.0.0. To match the criteria to a 24-bit subnet (for example, 192.168.10.0/24), use a wildcard mask of 0.0.0.255.
•Destination Port—Includes a destination port in the match condition for the rule. The destination port is identified in the datagram header.
If you select the Destination Port, choose the port name or enter the port number.
