Port Range Enter a range of destination TCP or UDP port numbers to be tested. An entry is
required for TCP, TCP New, TCP Established, and UDP, and is not allowed for
other protocols. Separate multiple ports with commas. Separate ranges of ports by
colons.
Examples:
22 – filter on port 22 only
23,64,80 – filter on ports 23, 64 and 80
23:64,80,143:150 – filter on ports 23 through 64, port 80 and ports 143 through
150
Action Select whether to Drop, Reject, or Allow communications for the specified IP
address, subnet mask, protocol, and port range. Drop ignores the packet with no
notification. Reject ignores the packet and sends back an error message. Allow
permits the packet through the filter.
Generate rule to
allow service
You may wish to “punch holes” in your filter set for a particular protocol or service.
For instance, if you have configured your NIS server and wish to create an opening
in your filter set, select the NIS option and click the Add Rule button. This entry
adds a new rule to your filter set using the NIS -configured IP address. Other
services and protocols added automatically generate the necessary rule to allow
their use.
