I have read the how-to.
ok, so basically my problem is the whole 'disconnect when starting game' thing, but port forwarding hasn't seem to fix it. I've been trying to play cnc3 on steam, windows 7. I've looked for a solution for three days, but to no avail.
If i must be more precise, the game disconnects after everyone's loaded and even got the custom map if there is one. I've tried playing with high ranked people that shouldn't have the problem themselves.
Any suggestion will be helpful, and may get me closer to the solution.
note: hosting games like Minecraft and Garry's Mod works.
