How to Install a Satisfactory Server?

This guide shows you step by step how to set up a Satisfactory Dedicated Server – from installation and first world creation to port forwarding.

Requirements

• Operating system: Windows 10/11 (64-bit) or Linux (Ubuntu, Debian)
• Processor: 4 cores at 3.4 GHz+, strong single-core performance preferred
• RAM: At least 8 GB for 1-4 players, 16 GB recommended for larger factories or more players
• Storage: 25 GB free disk space
• Network: Broadband internet connection

Step 1: Install server files

There are two ways to get the server files:

Method A: Via Steam (easier)

1. Open your Steam library
2. Enable the Tools category in the filter settings
3. Search for Satisfactory Dedicated Server
4. Click Install and wait for the download to complete

Method B: Via SteamCMD (for headless servers)

Run SteamCMD and enter the following commands:

steamcmd +force_install_dir C:\SatisfactoryServer +login anonymous +app_update 1690800 validate +quit

For Linux:

./steamcmd +force_install_dir ~/SatisfactoryServer +login anonymous +app_update 1690800 validate +quit

For the experimental version, replace public with experimental.

Step 2: Set up port forwarding

The following ports must be opened in your firewall:

• UDP 7777 – Game port (main connection for players)
• UDP 15777 – Query port (server information such as name, player count)
• UDP 15000 – Beacon port (optional, for multiple server instances)

Windows Firewall (PowerShell as Administrator)

New-NetFirewallRule -DisplayName "Satisfactory Server" -Direction Inbound -Protocol UDP -LocalPort 7777,15777,15000 -Action Allow

Linux (UFW)

sudo ufw allow 7777/udp
sudo ufw allow 15777/udp
sudo ufw allow 15000/udp

Then forward the ports in your router to your server's local IP address.

Step 3: Start the server

Navigate to the installation folder and start the server:

• Windows: Run FactoryServer.exe -log -unattended
• Linux: Run ./FactoryServer.sh

The first start may take a little longer. Logs will appear in the console showing that the server is running.

Step 4: Set up the server in-game (Server Manager)

1. Launch Satisfactory on your PC
2. Click Server Manager in the main menu
3. Click Add Server
4. Enter your server IP and port 7777
5. Confirm with Confirm
6. You will receive a message that the server is not yet configured
7. Assign a Server Name and confirm
8. Set a Server Password and confirm
9. Switch to the Create Game tab and select a starting area
10. Assign a session name and click Create Game

Step 5: Join the server

1. Open the Server Manager in-game
2. Select your server from the list
3. Enter the server password
4. Click Join Game

Step 6: Adjust server configuration

The configuration files can be found in the server directory under FactoryGame/Saved/Config/. Important files are:

• GameUserSettings.ini: Player count, server name, password
• Engine.ini: Network and performance settings
• Game.ini: Game rules and advanced settings

Common problems

• Server running but no one can join: Check firewall and port forwarding for UDP 7777 and 15777
• Server not found in the list: Make sure UDP 15777 is open
• Connection drops: Check the bandwidth settings in Engine.ini
• Game crashes when connecting: Since Update 1.1, TCP port 8888 is additionally required
• Server not saving: Always stop the server with the quit command, don't close the window
