Which ports does an Avorion server need?

By default, port 27000 (TCP and UDP) for the game, and ports 27003, 27020, and 27021 (UDP). The installer opens them in the Windows Firewall and, when you install through the dashboard, in your VPS's network firewall too.

Avorion: Set Up a Server on Your VPS

Learn how to install an Avorion server on your VPS with the Game Server Installer, open the required ports, and keep it up to date → Learn more

Introduction

You can host an Avorion server on your own VPS with ZapX. You have full control over the system, and the Game Server Installer gets your server set up in just a few minutes, without a remote desktop connection. This guide explains what you need, how to install the server, and how to manage it afterward.

Requirements

Requirement	Avorion
Operating system	Windows Server 2019 or newer
Memory	At least 3 GB
Free disk space	At least 5 GB on drive C:

Info

Avorion is only available for Windows in the Game Server Installer. If your VPS runs Linux, install a Windows Server template via Settings > Reinstallation. This deletes all data on the VPS. Learn more in Server Reinstallation.

Install Avorion

Open your VPS in the ZapX dashboard and go to the Tools tab. Select the Game Server Installer.
Under Your server's operating system, select the Windows tile.
Under Choose game, search for Avorion and select it.
Under Set up server, set the Server name, Player slots, World seed, and your Steam ID under Admin (Steam ID64). You can find the Game port and Query port under Advanced settings.
Click Install on this VPS, then click Start installation.

The installer downloads the Avorion server via SteamCMD, sets it up, and starts it. For details about the installation process, see the Game Server Installer guide.

Important

The galaxy is generated from the world seed the first time the server starts, and the seed cannot be changed afterward. If you leave the field blank, a random seed will be used. If you don't enter a Steam ID under Admin (Steam ID64), nobody will have admin privileges on the server.

You can also install Avorion yourself using a command. To do this, copy the command shown in the final step, connect via Remote Desktop, and run it in Windows PowerShell as an administrator.

After installation

When the installation is complete, the installer shows your server address under How to connect. Any passwords generated by the installer are shown once under Login credentials. Learn how to connect in Avorion: Connect to Your Server.

Your server files are on the VPS at C:\ZapX-GameServers\avorion\:

Folder/file	Contents
`server\`	Avorion server files
`data\avorion_galaxy\`	Your galaxy and the settings in `server.ini`
`logs\server.log`	Server output

Start, stop, and restart the server

Your Avorion server starts automatically when the VPS boots and restarts if it crashes. To manage it, connect via Remote Desktop and use the shortcuts on the desktop:

Avorion (avorion) - Start
Avorion (avorion) - Stop
Avorion (avorion) - Restart

Configuration

Avorion's settings are in data\avorion_galaxy\server.ini. The server rewrites this file when it shuts down. So stop the server before editing the file, then start it again afterward. RCON is disabled until you set an RCON password in the file. Learn more in Avorion: RCON.

Update the server

Updates are not installed automatically. To update, open the Game Server Installer again and select Avorion. The installer detects the existing installation and displays Update. Alternatively, use the Avorion (avorion) - Update shortcut on the VPS. Your settings and galaxy will be preserved.

Ports and firewall

Port	Protocol	Use
27000	TCP and UDP	Game
27003	UDP	Query
27020	UDP	Steam query
27021	UDP	Steam master

The installer opens these ports in the Windows Firewall. If you start the installation from the dashboard, it also opens them in your VPS's network firewall. If you installed using a command, check the ports there yourself.

Backups

Use the Avorion (avorion) - Backup shortcut to back up your galaxy as a ZIP file at C:\ZapX-GameServers\_backups\avorion\. Use Avorion (avorion) - Restore to restore a backup.

Your entire VPS is also backed up automatically every day. With an active ZapX Pass, you can restore these backups yourself and create your own. Learn more in Daily Backups, Restores, and Locked Actions.

Set up Avorion manually

If you'd rather set up the server yourself using SteamCMD, follow the steps in our guides for Windows and Linux.

Conclusion

Your Avorion server is now running on your VPS. You can become an admin using the Steam ID from the installation. Learn more in Avorion: Become an Admin on Your Own Server. If you have any questions or need help, our support team is here for you every day! 🙂

FAQ

Frequently asked questions

Open your VPS in the ZapX dashboard, go to the Tools tab, and select the Game Server Installer. Choose Windows and Avorion, configure the settings, and click Install on this VPS.

Not with the Game Server Installer, which only offers Avorion for Windows Server 2019 or newer. You can also set up the server manually on Linux using SteamCMD. See our Avorion guide for Linux.

It's at C:\ZapX-GameServers\avorion\data\avorion_galaxy\server.ini. Stop the server before editing the file, as Avorion rewrites it when shutting down.
