Ok so I have a ADSL modem which the isp has NAT on I obviously can't change this so I have my Airport in bridge mode so I don't get double nat.

Now what I want to do is make a little private cod4 server for my friends ect. Well the problem is that I can't figure out how to open my ports with my airport extreme base station?

I know I need:
UDP:28960
UDP:20800
UDP:20810

open and when I do http://www.yougetsignal.com/tools/open-ports/ it says they are closed. And of course when I try joining the server by typing connect "my external ip here" it doesn't find it.

Any ideas? I would really like to get this working! Thanks

ok I figured out my isp's username and pass. I added the ports (at least I think I did), but it still won't open.

Weird thing is that if I ping my computers local ip and port 10.146.12.4:28960 from another computer within the network it won't connect!

Any ideas?
