Server Requirements

Before we jump into the technicalities, let’s take a look at the hardware requirements for hosting a Barotrauma server. The following are the minimum and recommended server specifications:

Processor: Dual-core 2.0 GHz
Processor: Quad-core 2.4 GHz or higher

Server Software

The next step after purchasing the right hardware is to get the necessary software for running the server. The following are the software requirements for hosting a Barotrauma server:

  • Barotrauma Dedicated Server
  • SteamCMD

You can download the Barotrauma Dedicated Server from the Steam store or through SteamCMD. Once you have downloaded and installed the server software, you can then move on to the next step of setting up the server.

Setting Up the Server

Creating a Dedicated Server

After installing the server software, you will need to start the server for the first time to create a dedicated server. Follow these simple steps:

  1. Launch SteamCMD and log in to your Steam account.
  2. Enter the following command to download the Barotrauma Dedicated Server:
  3. app_update 1026340

  4. Once the download is complete, enter the following command to start the server:
  5. start dedicated_server

  6. Wait for the server to start up, and then enter the following command to create a new game:
  7. new_game

  8. Customize your game settings and click on “Start Game” to start your server.

Port Forwarding

If you want other players to connect to your server, you will need to forward the necessary ports on your router. By default, the port used by Barotrauma is 27015. Follow these steps to port forward:

  1. Open your router’s settings page.
  2. Locate the “Port Forwarding” section.
  3. Add a new forwarding rule and enter the following:
    • Protocol: UDP
    • Port: 27015
    • IP Address: Your server’s internal IP address
  4. Save the settings and restart your router.
  5. You can now share your server’s IP address and port with your friends, and they can join your game by entering it in the game’s multiplayer menu.


Why is my server not showing up on the server list?

If your server is not showing up on the server list, make sure that you have forwarded the necessary ports on your router. Also, check if your firewall is not blocking the server’s connection. You can also try restarting the server or checking for updates to see if that solves the issue.
