Guide: Run and Host a Nitrox Subnautica Server

This guide contains all the important information you need to know if you’re looking into hosting and creating a subnautica multiplayer server with Nitrox.

If you want to find out how to join a server, please read the join guide first.

Important notes:

  • The Nitrox server needs an open port to communicate through. This can be achieved by port forwarding or through the use of a VPN service like Hamachi if you do not know or want to port forward.
  • Nitrox uses port 11000 UDP
  • In some cases, your Firewall may be blocking this connection. If you or others can’t connect, make sure that both you and the host of the server have a firewall exception for the Subnautica.exe and NitroxServer-Subnautica.exe

Follow these steps to run/host a Nitrox server.

  1. Run NitroxLauncher as Administrator
  2. Click on Server, then Start Server

If you look in the server window you can find information about:

  • Game Mode
  • Server Password
  • Admin Password
  • Your local IP for LAN or if you are joining the server yourself
  • It shows you the IP others need to input, if you are Port Forwarding your server
  • Type help to get a full list of all Nitrox commands
