A Valheim dedicated server is a standalone version of the game that runs 24/7, allowing players to join a persistent world without the host needing to be online. It operates via server software that manages world data, player connections, and in-game events. Players connect via IP addresses or Steam invites, with settings customizable via configuration files.

How to Set Up a Valheim Dedicated Server?
Setting up a Valheim dedicated server involves downloading the server tools via Steam, configuring the start_headless_server.bat file with your world name and password, and forwarding ports 2456-2458 on your router. Hosting providers like GTXGaming or SurvivalServer offer one-click setups for hassle-free deployment.
For self-hosting, ensure your system meets the minimum requirements and follow these steps: 1) Install SteamCMD to download server files. 2) Create a dedicated folder for server data. 3) Edit the batch file to include your server name, password, and world file. Beginners often overlook router configuration – failure to forward ports 2456-2458 (TCP/UDP) remains the most common connectivity issue. Third-party hosts simplify this process through web-based control panels but cost $10-$25/month. For temporary worlds, consider using Valheim’s “Community Server” option, though it lacks 24/7 uptime.
How Does Port Forwarding Work for Valheim?
Port forwarding directs external traffic to your server’s local IP via router settings. For Valheim, TCP/UDP ports 2456-2458 must be open. This allows global players to connect using your public IP address. Tools like PortCheckScanner verify if ports are accessible, while VPNs or dynamic DNS services simplify connectivity.
| Port Number | Protocol | Purpose |
|---|---|---|
| 2456 | TCP/UDP | Primary game connection |
| 2457 | UDP | Steam query port |
| 2458 | UDP | Server browser listing |
Modern routers often include UPnP settings that automate port forwarding, but manual configuration provides better stability. Security-conscious admins should pair port forwarding with firewall rules limiting traffic to Valheim’s executable. Cloudflare Tunnel offers secure alternatives to traditional port forwarding, encrypting data without exposing your public IP.
What Are the System Requirements for Hosting?
Valheim dedicated servers require a minimum of 4GB RAM, 2 CPU cores, and 2GB of storage. For 10+ players, 8GB RAM and 4 CPU cores are recommended. Linux servers perform better for high-traffic worlds, while Windows setups are simpler for beginners.
Can You Mod a Valheim Dedicated Server?
Yes, mods like ValheimPlus and BepInEx can be installed on dedicated servers. Mods must match client-side versions to prevent crashes. Server admins upload mod files to the plugins folder and configure doorstop_config.ini to enable them. Unsupported mods may cause instability or bans.
Expert Views
“Valheim’s dedicated server thrives on simplicity but demands careful resource management. Prioritize RAM allocation and regular world backups—unexpected crashes can erase weeks of progress. For modded servers, test updates in a duplicate environment first. Crossplay limitations are a hurdle, but community tools like SteamCMD bridges help.”

FAQs
- What Are the Minimum Requirements for a Valheim Server?
- A 4GB RAM, dual-core CPU, and 2GB storage suffice for small groups. Larger groups need 8GB RAM and quad-core CPUs.
- How Many Players Can Join a Valheim Server?
- Official player caps are 10, but mods like ValheimPlus allow 64+ players. Performance degrades beyond 20 without optimizations.
- Can Xbox Players Join Steam Dedicated Servers?
- Indirectly, via community servers. Xbox users manually input the server IP but can’t access modded or password-locked worlds.
