TCP/UDP Port Filters
The AWK-1137C's TCP/UDP port filter is a policy-based filter that can allow or filter out TCP/UDP-based packets
with a specified source or destination port.
The AWK-1137C provides 32 entities for setting the range of source/destination ports of a specific protocol. In
addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or both. The end
port can be left empty if only a single port is specified. Of course, the end port cannot be larger than the start
port.
The Application name is a text string that describes the corresponding entity with up to 31 characters.
Remember to check the Active check box for each entity to activate the setting.
