How To Configure Your Arma 3 Server

Learn how to configure your Arma 3 dedicated server using server.cfg and Startup settings.

Arma 3 server configuration is handled through the server.cfg file and the Startup settings in your panel. Here is an overview of the key settings you can adjust.

Using Startup Settings

Open the Startup Page

Adjust the Available Settings

The Startup page provides fields for the most common settings including:

Server Name - The name shown in the server browser
Max Players - Maximum number of player slots
Server Password - Password to join the server
Admin Password - Password for admin login
Map - The map/terrain to load
Mods - Steam Workshop mod IDs

Restart Your Server

After making changes, restart your server from the Console page.

Editing server.cfg

For more advanced configuration, you can edit the server.cfg file directly.

Open Files

In the sidebar, click Files and open the server.cfg file.

Edit the Configuration

Here are some commonly used settings:

// Server Name
hostname = "My Arma 3 Server";

// Passwords
password = "";
passwordAdmin = "myadminpassword";

// Network
maxPlayers = 32;

// Voting
voteMissionPlayers = 1;
voteThreshold = 0.33;

// Mission rotation
class Missions {
    class Mission1 {
        template = "mission.Altis";
        difficulty = "Regular";
    };
};

Save and Restart

Save the file and restart your server from the Console page.

📝 Note: Settings in the server.cfg file may be overridden by Startup parameters. If a setting does not seem to apply, check whether it is also set in Startup.
