Reproduce: in Windows OS, install MegaGlest 3.6.0.2, start game, internet game, host game. It correctly shows among games in lobby (MegaGlest check for port fowarding runs ok). However clients connect and get disconnected (almost) immediately. Sometimes client "almost" joins.
Tested on: different windows (vista 32bit, windows 7 64bit) and different computers, graphic cards, etc. Confirmed/tested by tomreyn as well.
This is new issue, it worked before. I'm sorry, I don't know in exactly what version (3.6.0.2 or previous betas?), but it was quite recent.
In other words, guy with windows OS can host an internet game, but nobody would be able to join it.
Thnx a lot.
