Excuse me but even if you have port mapping on doesn't mean that you've set it up correctly. Which must be the case since it's not working for you! Try not to be so short with people and you might get even more help. I've never been short with one person on this board and hate to see someone being that way with me.

I posted that message late after doing lots of research on my own Airport port mapping issue and appoligize for not at least giving you a smiley face so that you would understand that I am friend not foe. In the future I will not respond to one of your post unless I have more time to be a bit more clear. I did at least give you a couple links that I thought would be very helpful, which seems to be a lot more than anyone else has given you. The Apple message board seems to have lots more information on port mapping than MacNN.

I can tell you this: Apple's port mapping is not very good at this point and probable needs a firmware update to fix it. I have mine set up correctly and strangly enough I can host an online game but can not join one. Your a bit of a gamer, maybe you have an answer for that?

Again, there are some topics over at Apple message boards that will probable be pretty helpful if you cared to look.

God Bless!
