Railroad Tycoon 2 can be played over Hamachi by following two basic steps will be required for this to work:
- Install Hamachi and join a network with your friend(s). Follow the steps on the Hamachi setup page, on how to install Hamachi and create and join networks.
- Join a game through TCP/IP. With all of your friends in the same Hamachi network and online, start up Railroad Tycoon. Click on multiplayer and then TCP/IP. If you’ve installed hamachi properly the IP in the “Your IP” box should be your Hamachi IP. Now one player should host, and if your firewall is configured correctly their game should appear for the other players. If not you can try entering their Hamachi IP or letting other players host.
- Make sure TCP/UDP 7242 ports are open, and that Hamachi and Railroad Tycoon 2 are unblocked on your firewall. Hamachi can confuse your firewall because it is recognized as a connection to an outside network on some operating systems, especially Windows 7. Try adding Hamachi as an exception to your firewall settings, but if that still doesn’t work you can turn off firewall for Public Networks in Control Panel/Windows Firewall. MAKE SURE that this doesn’t open your system up to outside threats. Do this at your own risk!
