How to Configure Your Arma Reforger Server (Config Editor & config.json)
Configure your Arma Reforger dedicated server using the built-in Config Editor tool or by editing config.json manually.
XGamingServer includes a built-in Arma Reforger Config Editor — a visual tool that eliminates manual JSON editing. You can also edit config.json directly if you prefer.
Open the Config Editor
In the XGamingServer Panel, click Arma Reforger Config in the sidebar (or click Open Config Editor on the dashboard banner).
Choose a tab
The editor has 5 tabs:
| Tab | What you configure |
|---|---|
| Network | Bind address, bind port, public address, public port |
| Game | Server name, max players, password, admin password, scenario, platforms, admin IDs |
| Properties | View distance, grass distance, BattlEye, third person, VON settings |
| Mods | Search & add Workshop mods, manage mod list, import/export |
| Optional | A2S query, RCON, operating settings, persistence |
Edit the values
Use the form fields to adjust settings. The editor validates input as you type so you can't accidentally write broken JSON.
Save Changes
Click Save Changes at the top. Most settings take effect immediately — a few require a server restart from Console.
Editor Features
- Scenario dropdown — 29+ official scenarios with friendly names
- Workshop mod search — search by name, author, or mod ID with auto-dependency resolution
- JSON preview — toggle to see the raw JSON being generated
- Export/Import — download or copy your config as JSON
Stop the server
Go to Console in the panel and stop your server.
Open config.json
Click Files in the sidebar and open config.json in the server root.
Edit settings
Make your changes. Valid JSON syntax is required — quotes around all strings, commas between fields, no trailing commas.
Save and start
Click Save Content and start the server from Console.
Warning: Invalid JSON syntax will prevent the server from starting. Use the Config Editor to avoid this — it validates as you type.
See the config.json Reference for every available setting.
