thanks Scott Kevill for registering and posting here this great news.... a lot of people were still unable to play because of these problems.
Thanks again for Gameranger, this is an awesome free concept!
PS : I'd like to know how you've managed to fix the wrong IP problem, because the origins are varied and I sometimes had no solution.
PS N° 2 : Just a feedback idea to improve GR : it would be interesting to allow users to configure the software port with the port they want because sometimes 2 personns on the same local network want to play on gameranger with 2 different PCs and only 1 redirection is possible for each port in their router.
But I suppose it implies to link IP+Port in your server for each user and send packets to "IP:Port x" and not only to "IP:port 16000".
All the best!
The best defence is attack!
