I need to open a specific port on my mac client (because when I try to connect from server it says "target machine actively refused it ").My problem though is I cannot find a way to add a specific port on my latest Mac OS.

I go to system pref->securtiy &privacy->firewall-> turn it on (FWIW connection didnt work when I had turned it off)->Firewall options->"+"

This gives me an option to add some application but not a port .Can someone point me to the right place to add the port?

Is there a program listening for connections on that port? If not, it's closed pretty much by definition. – Gordon Davisson Jun 21 '12 at 4:58
That is what my question was ..I dont think it is and that is why I wanted to open it ..not sure how to do it though. – Manish Jun 21 '12 at 23:06
