criteria and configurable fields are as follows:
•
Destination IP Address:
Requires a packet’s destination IP address to
match the address listed here. In the
IP Address

destination IP address in dotted decimal format. In the
IP Mask
field, enter
a valid subnet mask to determine which bits in the IP address are
significant. Note that this is
not
a wildcard mask.
•
Destination Layer 4 Port:
Requires a packet’s TCP/UDP destination port to
match the port you select. Select the desired L4 keyword from the list on
which the rule can be based. If you select Other, the screen refreshes and
