A wildcard mask of 0.0.0.0 indicates that none of the bits are important. A wildcard of 255.255.255.255 indicates that all of the bits are important. • Dst. In the Dst field, enter a destination IP address, using dotted-decimal notation, to be compared to a packet's destination IP address as a match criterion for the selected IP ACL rule: - If you select the IP Address radio button, enter an IP address with a relevant wildcard mask to apply this criteria. If this field is left empty, it means any. - If you select the Host radio button, the wildcard mask is configured as 0.0.0.0. If this field is left empty, it means any. The wildcard mask determines which bits are used and which bits are ignored. A wildcard mask of 0.0.0.0 indicates that none of the bits are important.

Each of these values translates into its equivalent port number, which is used as both the start and end of the port range. Select Other from the menu to enter a port number. If you select Other from the menu but leave the field blank, it means any. The relevant matching conditions for L4 port numbers are as follows: • Equal.

The IP ACL rule matches if the Layer 4 destination port number is less than the specified port number. • Greater Than. The IP ACL rule matches if the Layer 4 destination port number is greater than the specified port number. • Not Equal. The IP ACL rule matches only if the Layer 4 destination port number is not equal to the specified port number or port protocol. Manage Device Security 355
