Absolute power.

try playing through Tunngle. Maybe we can even play together if you want.

Thanks, but unfortunately, with my internet connection, it's not possible to fix the tunnel through a relay using Tunngle (you can still somehow configure a direct tunnel in Hamachi). I've tried configuring it and forwarding ports. It seems that the wireless connection is causing these problems.
However, if you're willing to help with the setup (maybe you know better), I would be grateful.
