I cant seem to find how to open a specific port in the ML firewall? I know you can give applications permisiion, but thats no good to me. Is there a way I can specify a specific port?

Can you explain what you're trying to achieve, and why allowing an application permissions doesn't solve it? If you don't have a program listening on that port, opening it in the firewall doesn't do any good; if you do have a program listening, just allow that program in the firewall. –  Gordon Davisson Sep 7 '12 at 16:22
    
I know it's an old question. Nonetheless I don't understand the downvote. The Op clearly asked what he was trying to achive: opening a port on the internal firewall. There are many reasons for this without the need of a specific application. –  cyphorious Aug 29 '13 at 14:32

This explains how to open a port by using the terminal. Otherwise you will need to download a program such as IceFloor or WaterRoof if you want a GUI.

That opens a port in the ipfw firewall, which is already wide open by default. In order to do anything useful, you have to be dealing with the application firewall (alf aka socketfilterfw aka a bunch of other names). –  Gordon Davisson Sep 7 '12 at 16:20
