Arma Reforger BattlEye Config Helper
Safely generate the lines to append to BEServer_x64.cfg — RConPort, RConPassword, RestrictRCon, MaxPing. Alphanumeric password validator with crypto-secure generator, plus recovery steps for corrupted BattlEye configs.
Your server auto-generates GameID and MasterPort lines — touching those breaks BattlEye and disconnects all players. Always APPENDnew settings, don't modify existing ones.
BattlEye settings
Enter an RCon password before using this config, or click Generate to create a secure random one. BattlEye RCon will not work without a password.

Full file example (if starting fresh or file is missing)
# Arma Reforger BattlEye Config
# DO NOT erase existing auto-generated lines (GameID, MasterPort)

RConPassword YOUR_PASSWORD_HERE
RestrictRCon 1
Only use this if BEServer_x64.cfg does not exist yet. The server will add GameID and MasterPort lines automatically on first boot.
What is BEServer_x64.cfg in Arma Reforger?
BEServer_x64.cfg is the configuration file used by BattlEye's server-side anti-cheat process for Arma Reforger. The _x64 suffix is mandatory for Reforger — BattlEye will ignore a plain BEServer.cfg on Reforger, unlike earlier Arma titles. The file lives in the battleye/ folder inside your server install. It is generated automatically on first server boot with two critical lines: GameID and MasterPort. Those lines are handshake tokens between your server and BattlEye's master service — if they are removed or edited, BattlEye disconnects every player and kicks your server off the public browser.
BattlEye Config vs Game Config — What's the Difference?
Arma Reforger has two separate RCon systems. The game's own RCon is configured inside config.json under the rcon block — this handles in-game admin commands like kicking, banning, and sending messages. BattlEye's RCon, configured inside BEServer_x64.cfg, is a separate listener used by external tools (BEC, BattleWarden, etc.) to pipe BattlEye events and broadcasts. They use different ports, different passwords, and different protocols. Changing one does not affect the other.
BattlEye Config Settings Reference
| Setting | Type | Default | Description |
|---|---|---|---|
| RConPort | number | none | BattlEye RCon listener port. Must not conflict with other services. |
| RConPassword | alphanumeric | none | RCon login password. Max 24 characters. No symbols allowed. |
| RConIP | string | 0.0.0.0 | Optional. Bind RCon to a specific IP — use 127.0.0.1 to restrict to local tools. |
| RestrictRCon | 0 / 1 | 0 | Restricts the set of RCon commands clients can run. Recommended: 1. |
| RConAllowPrivIPs | 0 / 1 | 0 | Allow RCon connections from private IP ranges (10.x, 192.168.x, etc.). |
| RConAutoHeartbeat | 0 / 1 | 0 | Enables automatic keepalive pings — useful for long-running admin tools. |
| MaxPing | number (ms) | not set | Kicks players whose ping exceeds this value. |
Why Password Can Only Be Alphanumeric
BattlEye's RCon protocol dates back to Arma 2 and uses a very lightweight wire format. Special characters, spaces, and punctuation can break the parser mid-handshake — some symbols are interpreted as field delimiters. Bohemia documents the limit as alphanumeric only (A-Z, a-z, 0-9) with a 24 character cap for Arma Reforger. If you need higher entropy, use all 24 characters of mixed-case letters and digits — that gives roughly 143 bits of entropy, which is stronger than most passwords on the internet.
File Location
- Windows:
<server_root>\battleye\BEServer_x64.cfg - Linux:
<server_root>/battleye/BEServer_x64.cfg - On XGamingServer hosts: the file is visible in your game panel's File Manager inside the
battleye/folder. Edit it with the built-in editor or download, edit, and re-upload.
Recovery if BattlEye Breaks
If BattlEye stops accepting connections or players get a "Missing GameID" error:
- Stop the server fully (not just a restart — full stop).
- Delete
battleye/BEServer_x64.cfg. - On Steam hosts: verify game file integrity via Properties → Local Files.
- On dedicated servers: run SteamCMD with
app_update 1874900 validate(the Reforger server AppID). - Start the server — the file regenerates with the correct GameID and MasterPort.
- Append your RCon settings back — do not replace the auto-generated lines.
