Server

From OpenTTD

If you want to host multiplayer network games, you need to set up the OpenTTD server on your computer.

1. From the Main Menu, click Multiplayer
2. Click Start Server
3. Choose a random new game (default) or one of the available scenarios
4. Pick a name for your game to help others identify it, and enter it into the Game name box
5. Configure the additional settings, explained below
6. Click Start Game to begin - this will then allow players to join

[edit] Settings

• Set Password sets a password for the server so that only users who know the password can join your game.
• Connection specifies whether the server is for LAN use only, or if it advertises itself to the master server so that it shows up in the internet server list.
• Max clients limits the total number of players that can connect.
• Max spectators limits the number of clients who can connect to watch but not play.
• Language Spoken is for requesting that users speak a certain language on your server.
• Load game is used if you want to continue an existing game - apart from the fact it's an existing map, it will restart the game in the same way as Start Game and players will then be able to join.

[edit] Ports

If your computer is behind a firewall or NAT router, you should check that the correct ports are open or forwarded.

[edit] Dedicated server

If you are expecting many players and aren't going to be using the machine yourself to play, you can start OpenTTD as a dedicated server instead of the usual interactive graphical version.
