Hello everyone.
I have an ADSL connection with Windows XP, my friend has a dedicated connection with Windows XP, and we also have a 3G modem with Windows 7. Neither of us has a dedicated IP address. The game version is 4.0.0.0. I would be very grateful if you could tell me how to do this. I'm confused by everything I've read, so if there's already a detailed answer, please provide a link, or you can send it to me in a private message.
P.S. Years go by, and I still haven't been able to play online.
