The best way to experience the multiplayer variety of Arma Reforger is on your own server. You can play multiplayer battles in conflict mode or in the “Capture & Hold” mode. You can also enjoy an individual adventure with a game master in Everon mode. Once you have the necessary server equipment, simply set up the Arma Reforger server using SteamCMD.

Dedicated resourcesUnlimited trafficPersonal consultantIf you want to host your own multiplayer sessions in Arma Reforger, we recommend renting external hardware. You can also run the server application on your own computer, however, there are certain specifications required for the resource-heavy military simulator, for example, for RAM, CPU and bandwidth
Arma Reforger was released in May 2022. According to developer Bohemia Interactive, the game represents an intermediate step between Arma3 and Arma 4, which is currently in development.
You can choose between the following three servers with IONOS:
You can always rely on the performance in your plan, even if you share the hardware with other customers, as is the case with servers with virtualized resources. For example, an external server’s broadband connection with up to 400 Mbit/s is guaranteed regardless of the model selected.
Making the choice between vServer and Cloud Server depends on the number of resources being used. If you only want to use the Arma Reforger server from time to time, the cloud server model is most suitable, since it has minute-by-minute billing. If you want to have the server active permanently, a vServer would be a better choice. A dedicated server would be ideal for server scenarios in which a large number of players will be involved.
In addition to the server model, IONOS also takes CPU performance and RAM and hard drive capacity into account when calculating the price for their different plans.
In the table below, we have outlined five possible use cases for an Arma Reforger server along with recommendations for a compatible IONOS server plan.
Arma Reforger server scenario | Recommended IONOS server |

> 16 players; server permanently online |
Would you like to play co-op missions on your own Arma Reforger server from time to time? If so, the Cloud Server L is the best choice for starting out. You can easily expand your plan if you find that you want to experience more adventures with more players.
You’re not limited to just hosting a gaming server when renting a server from IONOS. You could also run a TeamSpeak server at the same time to communicate with other players during gaming sessions.
Once you have decided on a server setup, it’s time to choose the operating system. You can choose between the classic Linux distributions and Windows Server. Regardless of which one you choose, installing the server software is supported by Steam’s command line client SteamCMD.
In the following tutorial, we will be using Windows Server software. Below, we’ll show how IONOS customers (vServer, Cloud Server, Dedicated Server) can install and set up an Arma Reforger server.
A remote desktop connection allows you to control and manage the server from a device of your choice. First, you need to set up the connection. As an IONOS customer, you can perform the remote configuration directly using the web-based Cloud Panel. All you need to do is follow these steps:
If you are connecting for the first time, you’ll have to confirm the server certificate when you log into the server. Check “Do not ask for connections with this computer again” to prevent this prompt from appearing in the future.
Begin with installing SteamCMD on your server. Download the Steam command line client package files using the following download link. Unzip the ZIP file into a folder of your choice and install the tool by double-clicking on the SteamCMD.exe.
Check out our article “Install SteamCMD” for a detailed guide on installing and using this client.
Download the Arma Reforger server application using the command line tool and install it on your server. To do this, log in anonymously to the public Steam servers:
login anonymousSpecify an installation folder for the server software in the next step, for example, C:\arma-reforger-server:
force_install_dir C:\arma-reforger-serverNow, start the application’s download. You need the “app_update” command and the Steam app ID for this. The identification number “Arma Reforger Server”. is “1874900”. Both elements should be combined in the command.
app_update 1874900 validate
Once the installation is complete, use the “quit” command to log out of the Steam servers.
The UDP ports 2001 (game port) and 17777 (port for Steam queries) must be opened to allow you and your fellow warriors to connect to the Arma Reforger server.
IONOS allows you to do this in the customer area. Simply log in and open the “Server & Cloud” section. Select your server package and click on “Network” and “Firewall Policies” in the left-hand menu. Enter the rules for the two ports under “Incoming”.
Opening the ports takes time. The status indicator in the upper part of the firewall menu will display its progress.
The next step is to configure the Arma Reforger server. Begin by creating a new folder called “config” in the server’s directory. In the “config” folder, create a new file named “config.json”.
You can now insert your individual server setup into the JSON file. The basic template looks like this:
{
}, "dedicatedServerId": "",
"}, "region",
}, "gameHostBindAddress": "",
"gameHostBindPort": 2001,
}, "gameHostRegisterBindAddress": "",
"gameHostRegisterPort": 2001,
"game": {
}, "name": "",
"}, "password",
"}, "scenarioId",
"playerCountLimit": 127,
}, "visible": true,
"gameProperties": {
"serverMaxViewDistance": 1600,
"serverMinGrassDistance": 0,
"networkViewDistance": 0,
"disableThirdPerson": false,
"fastValidation": true,
"battlEye": true
},
"mods": []
}
}Detailed descriptions of the individual parameters for the Arma Reforger server’s configuration files can be found in the official Bohemia Interactive community wiki. You will need to enter a “scenarioID” in order to specify the game mode. The available IDs can also be found on the Arma Reforger community wiki.
The “fastValidation” parameter, which is responsible for new clients’ initial connection, always has to have the value “true” for public servers (Version 0.9.5).
Once you have set up the configuration, you can start your Arma Reforger server. To ensure that the configuration file is accounted for when starting the server, create a simple batch script for the ArmaReforgerServer.exe file.
Create a new file called “start.bat”. Right-click on it and select “Edit”. Then, insert the following code and save the file:
ArmaReforgerServer.exe -maxFPS 60 -config ".\config.json"You can now start the Arma Reforger server at any time. To do this, simply double-click the batch file.
You will see the following two lines in the command prompt when the server starts:
DEFAULT: Entered online game state.
ENGINE: Game successfully created.This is the start signal for you and your fellow players to connect to the server. Complete the following steps to connect:
If you can’t find your server using the search function, you can press “Join directly” instead and enter the IP address of your server. Keep the port labeled as “2001”.
After a connection is established, the online adventure in the selected game mode can begin!
