How to Configure RCON for Your Arma 3 Server

Published June 9, 2026 · By Host Havoc Technical Support Team

RCON lets you manage your Arma 3 server remotely using tools such as BattleWarden. Configuration is done through a BattlEye config file that you create in the control panel file manager.

Once RCON is active you can also use it alongside headless client setups to manage AI offloading without being in-game.

Steps

  1. Log in to the Game Control Panel and navigate to your Arma 3 server.
  2. Open the File Manager and navigate to the A3DS/BattlEye directory.
  3. Create a new file:
    • If your server runs the x64 executable: name the file beserver_x64.cfg
    • If your server runs the x86 executable: name the file beserver.cfg
  4. Add the following to the file, replacing the placeholder values:
    RConPort <game port + 4>
RConPassword <your desired password>

    For example, if your game port is 2302:
    RConPort 2306
RConPassword changeme123
  5. Save the file.
  6. Restart the server.

Tip: Your RCON port is always your game port plus 4. If your game port is 2302, your RCON port is 2306.

After restarting, connect using your preferred RCON tool with the IP, RCON port, and password you configured above.
