Which ports does a Subsistence server need?

By default, port 7777 (UDP) for the game and port 27015 (UDP) for queries. The installer opens them in the Windows Firewall and, when you install through the dashboard, in your VPS's network firewall too.

Subsistence: Set Up a Server on Your VPS

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

Introduction

You can host a Subsistence server with ZapX on your own VPS. 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 installation works, and how to manage your Subsistence server afterward.

Subsistence: Set Up a Server on Your VPS

Requirements

Requirement	Subsistence
Operating system	Windows Server 2019 or newer
Memory	at least 4 GB
Free disk space	at least 4 GB on drive C:

Info

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

Install Subsistence

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 Subsistence and select it.
Under Set up server, choose the Server name and Player slots. 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 Subsistence server via SteamCMD, sets it up, and starts it. For details on how installation works, see the Game Server Installer guide.

Info

The installer generates the admin password for you and displays it once after installation under Login credentials. It is also stored in plain text in UDKDedServerSettings.ini, and therefore in every backup.

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

After installation

When installation is complete, the installer shows your server address under How to connect. You can view passwords generated by the installer once under Login credentials. Find out how to connect below.

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

Folder/file	Contents
`server\`	Subsistence server files
`server\UDKGame\SaveData\`	Your world and save files
`server\UDKGame\Config\UDKDedServerSettings.ini`	Server settings
`logs\server.log`	Server output

Connect to the server

You can find your VPS IP address in the Overview of your VPS in the ZapX dashboard. The installer shows the full address under Connect to. Start Subsistence, open Multiplayer, then open the server list. Search for your server name or connect directly using your VPS IP address and the port, which is 7777 by default.

Start, stop, and restart the server

Your Subsistence server starts automatically when your VPS boots and restarts after a crash. To manage it, connect via Remote Desktop and use the desktop shortcuts:

Subsistence (subsistence) - Start
Subsistence (subsistence) - Stop
Subsistence (subsistence) - Restart

Configuration

Subsistence settings are stored in server\UDKGame\Config\UDKDedServerSettings.ini. The installer rewrites the server name, passwords, and player slots each time it runs, so change these through the installer. You can edit all other values yourself. Stop the server first, then restart it after making your changes. The installer adds the query port to the engine configuration itself (DefaultEngine.ini or UDKEngine.ini, which is created after the first start). Change it using the Query port field in the installer, not manually.

Update the server

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

Ports and firewall

Port	Protocol	Use
7777	UDP	Game
27015	UDP	Query

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 Subsistence (subsistence) - Backup shortcut to save your world, save files, and UDKDedServerSettings.ini as a ZIP file at C:\ZapX-GameServers\_backups\subsistence\. Use Subsistence (subsistence) - 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. Find out more in Daily backups, restoration, and restricted actions.

Conclusion

Your Subsistence server is now running on your VPS. If you have questions or need help, our support team is here for you every day! 🙂
