How to Run a Game Server on a NAS

Running a game server on a Network Attached Storage (NAS) device is a great way to repurpose existing hardware, especially for home labs or small gaming communities. With increasing processing power and application support, modern NAS units can effectively host game servers for games like Minecraft, ARK: Survival Evolved, and Counter-Strike.

In this article, we'll walk you through the steps to set up a game server on a NAS, considerations to keep in mind, and which games are best suited for this environment.

What is a NAS?

A Network Attached Storage (NAS) is a specialized device that provides centralized data storage and access over a network. While originally designed for file sharing and backup, many modern NAS devices, especially from vendors like Synology, QNAP, and Asustor, support apps and virtualization features that make them suitable for running lightweight servers, including game servers.

Benefits of Running a Game Server on a NAS

• Always-On Availability: NAS devices are designed to be always on, perfect for hosting multiplayer sessions.
  
  

• Energy Efficient: Compared to running a dedicated PC 24/7, NAS devices consume less power.
  
  

• Compact Footprint: Saves space while still providing decent performance.
  
  

• Storage-Optimized: Ideal for games that require large world saves or mods (e.g., Minecraft with mod packs).
  
  

Prerequisites

Before setting up your game server on a NAS, ensure the following:

Suitable NAS Hardware

• Processor: At least a dual-core CPU (Intel/AMD preferred for better compatibility with virtualization).
  
  

• RAM: Minimum 4GB, but 8GB or more is better, especially for games like Minecraft or ARK.
  
  

• Storage: Ensure sufficient disk space for game files, backups, and logs.
  
  

• OS Support: Preferably DSM (Synology), QTS (QNAP), or Asustor's ADM with Docker, VM, or Container Station support.
  
  

Network Configuration

• A stable network connection, preferably via Gigabit Ethernet.
  
  

• Port forwarding configured on your router for external access (e.g., port 25565 for Minecraft).
  
  

• Static IP address for the NAS to avoid IP changes after reboot.
  
  

Step-by-Step Guide to Run a Game Server on a NAS

Step 1: Choose a Game Server

Some games are lightweight and run easily on NAS devices, while others require more resources. Good options include:

• Minecraft (Java Edition or Bedrock)
  
  

• Terraria
  
  

• Valheim
  
  

• Counter-Strike: Global Offensive (CS:GO)
  
  

• Rust (basic setups)
  
  

Step 2: Install Docker or Virtualization Package

Most NAS devices support Docker or virtual machines. Depending on your NAS brand:

For Synology:

• Go to Package Center > Install Docker.
  
  

• For VM setup, install Virtual Machine Manager (requires compatible CPU and RAM).
  
  

For QNAP:

• Use Container Station for Docker-based servers.
  
  

• Use Virtualization Station for full VM support.
  
  

For Asustor:

• Use Docker-CE via App Central.
  
  

Step 3: Deploy Game Server via Docker (Preferred for Lightweight Games)

Docker is the easiest and most efficient way to host game servers on a NAS.

Example: Minecraft Java Server on Docker (Using Synology/QNAP)

1. Launch Docker or Container Station.
   
   

2. Go to Registry and search for a Minecraft server image (e.g., itzg/minecraft-server).
   
   

3. Download the image and create a new container.
   
   

4. Configure ports (e.g., 25565:25565 for Minecraft), volume paths, and environment variables:
   
   

• EULA=TRUE
  
  

• MEMORY=2G
  
  

• Optional: set seed, game mode, etc.
  
  

5. Mount persistent storage volumes to save game data.
   
   

6. Start the container and monitor logs to ensure the server is running.
   
   

Step 4: Configure VM (For Resource-Intensive Games)

If Docker isn't available or your game requires more customization (e.g., ARK or CS:GO), consider creating a virtual machine hosting.

1. Create a new VM using Virtual Machine Manager (Synology) or Virtualization Station (QNAP).
   
   

2. Allocate sufficient resources (CPU, RAM, Storage).
   
   

3. Install a lightweight Linux distro (e.g., Ubuntu Server or Debian).
   
   

4. SSH into the VM and install the game server manually following its official instructions.
   
   

5. Open necessary ports in your firewall and router.
   
   

Step 5: Port Forwarding and Firewall Configuration

To make your server accessible over the internet:

1. Log in to your router's admin panel.
   
   

2. Set up port forwarding for the relevant game server ports to your NAS IP.
   
   

3. On the NAS, ensure the firewall is configured to allow inbound traffic to those ports.
   
   

4. Use dynamic DNS server (DDNS) to avoid relying on your public IP if you don't have a static IP.
   
   

Step 6: Connect and Play

Once your server is running:

• Use your NAS's IP or domain name (if using DDNS) to connect from the game client.
  
  

• Share the connection details with friends or community members.
  
  

• Regularly back up game data using NAS backup utilities.
  
  

Troubleshooting Tips

• Server Not Starting?
  
  

• Check logs in Docker or the VM console.
  
  

• Ensure game-specific environment variables are set correctly.
  
  

• Can�t Connect to Server?
  
  

• Recheck port forwarding settings.
  
  

• Ensure no firewall is blocking connections on the NAS or router.
  
  

• Performance Issues?
  
  

• Monitor CPU/RAM usage via NAS resource monitor.
  
  

• Reduce concurrent players or allocate more RAM to the container/VM.
  
  

Games Best Suited for NAS Game Servers

Here's a quick list of games and how well they typically run on a NAS:

Security Considerations

• Keep Docker images and game server software up-to-date.
  
  

• Use strong NAS user credentials and enable 2FA.
  
  

• Don't expose unnecessary ports to the public.
  
  

• Regularly back up game server data to a separate volume or cloud storage.
  
  

Conclusion

Running a game server on a NAS is not only possible-it's practical for many users with modest gaming needs. With the help of Docker or VM tools, you can easily host popular multiplayer games directly from your NAS device without investing in a separate server.

Whether you're hosting a private Minecraft world for friends or a Terraria server for your gaming group, your NAS can handle it-all while keeping your electricity bill low and setup compact.
