Ok got that to work, not when my friend tries to connect to my metaserver game and vice versa, it says "game not found".

Anyone know what might be causing this?

Could very well be a firewall or router issue.. I'm afraid I'm not too well versed in the possible solutions for that.
 
I've had the exact same problem with my friend trying to get an internet game together. Currently we're having a problem because the game says we don't have the same version.... so annoying.
However the answer to your problem (if you want to play a direct internet game, not metaserver) is the HOST of the game has to enable port forwarding on their router. You should be able to find all the info at www.portforward.com
Hope this helps.
