How do I update my Citadel server?

Open the Game Server Installer again and select Citadel: Forged With Fire. The installer will show Update. Alternatively, use the Citadel Forged With Fire (citadel-forged-with-fire) - Update shortcut on your VPS.

Which ports does a Citadel server need?

By default, port 7777 (UDP) for the game, 7778 (UDP) for Steam, and 27015 (UDP) for Steam query. The installer opens these in the Windows Firewall and, if you install through the dashboard, in your VPS's Network Firewall too.

Introduction

You can host a Citadel 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 installation works, and how to manage your Citadel server afterward.

Citadel: Forged With Fire: Set Up a Server on Your VPS

Requirements

Requirement	Citadel: Forged With Fire
Operating system	Windows Server 2019 or later
RAM	At least 4 GB
Free disk space	At least 6 GB on drive C:

Info

Citadel: Forged With Fire 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 your VPS. Learn more in Server Reinstallation.

Install Citadel: Forged With Fire

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 Citadel: Forged With Fire and select it.
Under Set up server, choose the Server name, Game mode (PvP, PvE, or Roleplay), 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 Citadel server via SteamCMD, sets it up, and starts it. For details about the installation process, see the Game Server Installer guide.

You can also install Citadel: Forged With Fire manually with a command: copy the command shown in the final step, connect via Remote Desktop, and run it in Windows PowerShell as an administrator. If you want a join password, use this method—the script will prompt you to enter it without displaying it.

After installation

When installation is complete, the installer shows your server address under How to connect. You can view passwords generated by the installer—including the automatically generated admin password—once under Login credentials. Learn how to connect in Citadel: Forged With Fire: Connect to the server.

Your server files are stored on the VPS at C:\ZapX-GameServers\citadel-forged-with-fire\:

Folder/file	Contents
`server\`	Citadel: Forged With Fire server files
`server\Citadel\Saved\SaveGames\`	Your world and characters
`server\Citadel\Saved\Config\WindowsServer\`	Settings in `Game.ini` and `Engine.ini`
`logs\server.log`	Server output

Start, stop, and restart the server

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

Citadel Forged With Fire (citadel-forged-with-fire) - Start
Citadel Forged With Fire (citadel-forged-with-fire) - Stop
Citadel Forged With Fire (citadel-forged-with-fire) - Restart

Configuration

Citadel: Forged With Fire settings are stored in server\Citadel\Saved\Config\WindowsServer\Game.ini and Engine.ini. Stop the server with Citadel Forged With Fire (citadel-forged-with-fire) - Stop before editing these files, then start it again afterward.

Important

The installer rewrites the server name, game mode, player slots, passwords, and ports in Game.ini every time it runs, including during an update. The WorldCreationSettings line is managed by the installer: any additional world settings you add there will be lost the next time it runs.

You can become an admin in-game: enter /admin_login <Admin-Passwort> in the chat. If you change the password in-game with /admin_update, the installer will reset it the next time it runs. To change it permanently, run the installer again using a command and set the ZX_ADMIN_PASSWORD environment variable in Windows PowerShell first:

Code

$env:ZX_ADMIN_PASSWORD = "<NEUES_PASSWORT>"

Info

The game saves the world every 2 minutes, so you could lose at most that much progress when stopping the server.

Update the server

Updates are not installed automatically. To update, open the Game Server Installer again and select Citadel: Forged With Fire. The installer detects the existing installation and displays Update. Alternatively, use the Citadel Forged With Fire (citadel-forged-with-fire) - Update shortcut on the VPS. Your world and characters will be preserved.

Ports and firewall

Port	Protocol	Use
7777	UDP	Game
7778	UDP	Steam
27015	UDP	Steam 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 via a command, check the ports there yourself.

The installer deliberately does not open the game's web remote console (game port + 2, TCP). It logs every login attempt, including the password entered, to server\Citadel\Saved\Logs.

Backups

Use the Citadel Forged With Fire (citadel-forged-with-fire) - Backup shortcut to back up your world and server settings as a ZIP file in C:\ZapX-GameServers\_backups\citadel-forged-with-fire\. Use Citadel Forged With Fire (citadel-forged-with-fire) - 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, restoring backups, and restricted actions.

Summary

Your Citadel server is now running on your VPS. To become an admin, enter /admin_login in the chat along with the admin password provided during installation. If you have any questions or need help, our support team is here for you every day! 🙂
