With this new version of PokerTH, you no longer need to exchange IP addresses and configure routers to play on the internet. We are running a dedicated server which will host all of your PokerTH games. Everyone who is willing to help with testing is invited to go to the download section and get a copy of PokerTH-0.6-beta. Just run the game and click on "Internet-Game" to join existing online-games or create your own one.
If you find a bug please report it in the forum or join our irc channel for comments.
Your PokerTH development team.
