• Source MAC Mask. Indicates which bits in the source MAC address are significant
and which are ignored. An F indicates that the bit is significant, while a 0 indicates that

address specified here.
• Destination MAC Mask. Indicates which bits in the destination MAC address are
significant and which are ignored. An F indicates that the bit is significant, while a 0

the address listed here. In the IP Address field, enter a valid destination IP address in
dotted decimal format.
• Destination Mask. Enter a valid subnet mask to determine which bits in the IP
address are significant. This is not a wildcard mask.
• Destination L4 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 a Port ID field appears. Enter a
user-defined Port ID by which packets are matched to the rule.
