This rule alows incoming connections (in case of TCP protocol) on the specified port. So it is applicable to both incoming and outgoing packets.
I noticed you said “in case of TCP protocol”…
So, let me see if i got it:
If using TCP protocol, this rule will allow incoming and outgoing trafic.
But what if i need the same kind of rule (incoming and outgoing) on the same port with UDP protocol? The rule would be the same?
Or do i need one rule to alow incoming and another to alow outgoing trafic on the same port?
