OUT: Specifies the rule for filtering outgoing packets.
Protocol: Specifies the protocol(s) this filter rule will apply
to.

If the End Port is empty, the port number is not equal to the
value of the Start Port. Otherwise, this port number is not
between the Start Port and the End Port (including the Start
Port and End Port).

Port (includes the Start Port).
< : Specifies the port number is less than the Start Port
(includes the Start Port).
Keep State: When checked, protocol information about the
TCP/UDP/ICMP communication sessions will be kept by the
IP Filter/Firewall (the Firewall Protocol option requires that
TCP or UDP or TCP/UDP or ICMP be selected for this to
operate correctly).
