Uhhh.... well, I'm not that deep with Linux. I've installed hamachi according to this Thread:

But I guess, I've found a solution for my problem. The hamachi Version for Windows seems to have some bug. With the newes Version I'm unable to play Titan Quest wth some friends of mine. If we use Version 1.0.1.5, erverything works fine. I'll install 1.0.1.5 later on my server and post the results.
