The tunngle lobby is already open from a month. With the game works perfectly (a part the game problem of fall of client player). Is the better solution if your connection is behind a NAT.
We get the same issues in direct play
But the other issue is reliablity with it is that going to be sound? And its free now but will it be always free? for example hamachi was good till someone else bought it out. Now its suspect in reliability.
A lot of the time something thats free, is not free of problems, therefore it costs time. I dont have the time to spare to muck around with it.
Id rather pay a small amount for a system that has guaranteed connections, got heaps of reliablitily and support for a strong basic system, than with something thats reliable some of the time, and the support you get only forum support at best.
NAT?
