How to Set Up a Farming Simulator 25 Server: A Full Guide

A Farming Simulator 25 dedicated server keeps your farm alive even when you’re offline. Your crops grow, animals move, and progress continues 24/7 for everyone who joins. It’s your always-on multiplayer world, stable, synced, and ready whenever you are.

You can host it yourself on a Windows PC for complete control or rent a high-performance server built for FS25’s single-thread-sensitive load. 

Moreover, FS25 server performance is primarily single-thread-limited (the simulation “tick” depends heavily on one fast core), while additional cores mainly help with background tasks and running multiple instances or other services.

Self-hosting gives freedom but needs setup and upkeep. Renting gives instant launch, DDoS protection, and console cross-play with no hassle.

This guide walks you through both options step-by-step, installation, configuration, networking, mods, update automation, and Linux/WINE hosting.

Key Takeaways 

• A Farming Simulator 25 dedicated server keeps your farm world active 24/7, so crops grow, animals move, and progress continues even when you’re offline.
• GIANTS provides a Windows-based dedicated server tool. Windows 10/11 are the standard supported route. Linux/WINE setups are community-driven and unsupported.
• Strong single-thread-sensitive CPU performance is critical. FS25’s server engine runs best on Ryzen 9, Core i9, or Xeon Gold chips with 4.5 GHz+ boost clocks.
• Use SSD or NVMe drives to reduce load times and autosave lag, especially for large maps or modded environments.
• Forward UDP 10823–10825 for game traffic. Keep the web panel (8080/8443) private, and only allow it via VPN or trusted IPs.
• Keep mods identical across all players and the server to prevent the “mod mismatch” error. Stick to ModHub-approved mods for stable cross-play support.
• Update via Steam/Epic/GIANTS installer, and automate restarts/backups with Task Scheduler.
• Schedule regular restarts and weekly backups to prevent long-uptime slowdowns and reduce the risk of save issues and accidental save corruption.
• Self-hosting offers full control and customization, while provider-hosted servers deliver faster setup, higher uptime, and integrated DDoS protection.
• RedSwitches bare-metal servers are purpose-built for FS25, featuring high-clock Intel / AMD CPUs, NVMe storage, 10–25 Gbps bandwidth, and 99.99 % uptime for lag-free farming.

Prepare Your Server Environment (Hardware, OS, Network)

Before launching your Farming Simulator 25 dedicated server, make sure your system meets the right technical foundation, strong hardware, a stable Windows setup, and reliable network capacity built for nonstop multiplayer play.

Operating System

• Use Windows 10/11 (64-bit) or Windows Server 2019/2022 (64-bit).
• Windows is the stable, documented route for a Farming Simulator 25 dedicated server setup.
• Linux setups via Wine or Docker are community-driven and unsupported by GIANTS.

CPU (Processor)

• FS25 partially uses multiple cores, but single-thread speed remains the priority
• Examples:
  • Intel Core i5-12400 / AMD Ryzen 5 5600 @ ≥3.5 GHz base
  • Higher clocks and newer architectures (12th-gen Intel / Ryzen 5000+) are recommended for larger servers.

RAM (Memory)

GIANTS dedicated server tool minimum: 4 GB RAM (practically, 8 GB+ recommended on Windows). (This does not account for Windows OS overhead.)

Practical minimum for a usable Windows server:
8 GB total system RAM, with approximately 6 GB available for FS25 after OS usage.

Recommended allocations:

• 8 GB total system RAM
  2–4 players, minimal mods, default map
  (Leaves ~5–6 GB usable for FS25 after OS consumption)
• 12–16 GB total system RAM
  6–10 players, moderate mods, larger maps
• 16 GB+ total system RAM
  Upto 16+ players (maximum supported by FS25)

Windows Server 2019/2022 typically consumes 2–3 GB RAM before the game server starts. Always leave headroom to prevent memory pressure and autosave crashes.

Storage

Install the OS, game files, and save data on an SSD or NVMe drive.

• Fast storage reduces load times, speeds up map switching, and eliminates mod-loading stalls.
• Avoid HDD-only setups for a 24/7 dedicated server.

Network (Uplink & Latency)

• Upload speed:
  • ≥10 Mbps – 2–4 players, no mods
  • ≥25 Mbps – 6–10 players or any mod use
  • ≥100 Mbps – 12–16+ players, public servers, global players
• Aim for low latency (<80 ms) to your primary player region.
• Default port: UDP 10823–10825 – forward in router and firewall
• Use a wired Ethernet connection (avoid Wi-Fi for the server).

Install the FS25 Dedicated Server on Windows: Step-by-Step Guide

Let’s discuss the step-by-step guide to install FS25 dedicated servers.

Step 1: License Activation

A dedicated server requires its own licensed copy of Farming Simulator 25, separate from any client used for playing.

• Purchase a second license (Steam, Epic, or GIANTS eShop).
• Install and launch the game once on the host PC to bind the license.
• Run as Administrator if activation prompts fail (common with Steam overlay).

Note: eShop keys avoid Steam overlay issues; use them if problems persist.

Step 2: Download and Install

User Data Path (all versions):

C:\Users\<YourUsername>\Documents\My Games\FarmingSimulator2025\dedicated_server\

Contains:

– dedicatedServerConfig.xml (runtime server settings managed by the web panel)

– mods\

– savegame*

– log.txt

Important: Two Different Configuration Files

Farming Simulator 25 uses two separate XML configuration files:

dedicatedServer.xml
Location:
C:\Program Files (x86)\Farming Simulator 25\

Controls:

• Server name
• Password
• Max players
• Region
• Savegame index
• Initial admin credentials

Root element:

<dedicatedServer>

This file is edited manually before first launch.

 dedicatedServerConfig.xml
Location:
C:\Users\<YourUsername>\Documents\My Games\FarmingSimulator2025\dedicated_server\

Controls:

• Gameplay settings
• Economy
• Active mods
• Settings changed via web panel

This file is automatically updated by the web interface. Do not confuse it with dedicatedServer.xml.

Step 3: First Run and Activation

1. Launch FarmingSimulator2025.exe (not the server).
2. Log in, accept EULA, allow firewall access.
3. Exit the game, full client no longer needed.

Verification: Confirm folders exist in the Documents path above.

Step 4: Configure dedicatedServer.xml

Edit the file in: 

C:\Program Files (x86)\Farming Simulator 25\dedicatedServer.xml

Use Notepad++ or any plain-text editor.

<?xml version=”1.0″ encoding=”utf-8″ standalone=”no” ?>

<dedicatedServer>

  <initial_admin>

<username>AdminUser</username>

    <passphrase>StrongUniquePass123!</passphrase>

  </initial_admin>

  <name>My Public Farm</name>

  <password>JoinPass2025</password>

  <maxPlayers>16</maxPlayers>

  <difficulty>normal</difficulty>

  <savegameIndex>1</savegameIndex>

  <region>eu</region>

</dedicatedServer>

Security: Passwords are stored in plain text; use strong, unique values.

Back up this file before every edit.

Step 5: Launch the Server

1. Navigate to: C:\Program Files (x86)\Farming Simulator 25\
2. Right-click dedicatedServer.exe → Run as administrator
3. Console shows:
   • Server started
   • Admin panel: http://localhost:8080 or https://localhost:8443 (prefer https)

The web admin shows two URLs: HTTP (8080) and HTTPS (8443). Prefer HTTPS for any remote access, and restrict access via VPN or trusted IPs.

• Listening on UDP 10823, 10824, 10825

Logs:

• Real-time: Console window
• Files: log.txt + log-YYYY-MM-DD.txt in Documents path

Web Admin & Files

FS25 provides the web admin on HTTP (8080) and HTTPS (8443). Use HTTPS when possible, especially for remote access. The <initial_admin> in dedicatedServer.xml is only used for the first login. After that, credentials are handled inside the web interface.

Web Admin Access

Once your Farming Simulator 25 dedicated server starts, open a browser on the host and go to:

• HTTPS: https://localhost:8443

Log in with the username and passphrase from the <initial_admin> block inside dedicatedServer.xml.

This grants first-time access and creates your persistent admin account. After this, user credentials are managed directly inside the web panel,  the XML entry is ignored on subsequent logins.

Security

• FS25 web admin is available on HTTP 8080 and HTTPS 8443. Use HTTPS (8443) when possible. Only expose the web panel if you must, and prefer VPN or IP allow-listing.
• Keep ports 8080/8443 private. If you need remote access, use a VPN or a trusted IP allow-list.

What You Can Control

From the web interface, you can:

• Start or stop the server.
• Change map, economy, or difficulty settings.
• Adjust player slots and permissions.
• Enable or disable mods and DLCs.
• Manage savegames and trigger restarts.

Each change updates the server configuration and applies on restart.

Where Files Live

Default data path (Windows):
C:\Users\<YourUsername>\Documents\My Games\FarmingSimulator2025\dedicated_server\

This folder includes:

• dedicatedServerConfig.xml – configuration file.
• mods\ – ZIP files for installed mods.
• savegame* – worlds and progress data.
• log.txt – activity and error log.

If changes don’t save or the web panel can’t write configs, run the server as Administrator. Windows permissions can block write access for normal users.

Expert Tip:

Your <initial_admin> credentials are plaintext. Protect the file until you’ve logged in once and created secure user accounts in the web panel. Then store a backup of your configured folder for future recovery.

Open the Right Ports (and Only the Right Ports)

Let’s make your Farming Simulator 25 server visible to players, without leaving any unnecessary doors open.

Game Traffic

FS25 multiplayer may require UDP ports 10823, 10824, and 10825 (forward and allow them in firewall).

Steps:

• Forward UDP ports 10823, 10824, and 10825 to your server’s LAN IP (for example 192.168.1.10).
• Make sure no other app uses these ports.
• Verify that your firewall allows inbound and outbound access for dedicatedServer.exe.

If these ports aren’t open, your server won’t appear in the multiplayer list or allow direct connections.

Admin Panel Access

FS25 includes a built-in web control panel.

• HTTPS 8443: Secure interface enabled by default.
• HTTP 8080: Web admin (local use). 
• HTTPS 8443: Web admin (preferred for remote use).

Security advice

• Only forward 8443 if you must manage the server remotely.
• Do not expose 8080 to the internet. Keep it LAN-only, or use VPN/IP allow-listing for remote admin access.
• Use a VPN or strict IP allow-listing for remote admin access.
• Never expose either port publicly, they grant full server control.

Router, NAT & Testing

Routers block incoming traffic by default. Port forwarding assigns that traffic to your server.
To confirm your setup:

• Test joining from an external network (mobile hotspot or a friend outside your LAN).
• Test that the server appears in the multiplayer list and that an external player can join.

If it fails:

• Re-check your router and firewall rules.
• Ensure your public IP hasn’t changed (some ISPs rotate addresses).
• Watch for conflicts; tools like TeamViewer or web proxies often use port 8080.

Mods, DLCs & Cross-Play: Smooth Joining Every Time

Let’s make sure every player joins your farm without errors, mismatched mods, or missing DLCs.

Keep Mods in Sync

Your server and players must share identical mod files and versions. If even one differs, you’ll see the dreaded “mod mismatch” error.

How to Add Mods:

• Open the web panel → Mods tab → add/enable mods (prefer ModHub for cross-play), click Save, then restart the server.

Best Practice:
Keep a shared mod pack for your players,  labeled with version numbers or dates. When a mod updates, replace it on both the server and all player PCs before restarting.

DLC Matching

If the server enables DLC-dependent content (maps, vehicles, features), players may need that same DLC to join and play correctly. To avoid join failures and missing content, align DLC between the server and your player group.

Recommendation:
Match your DLC setup with your player group for a consistent experience and fewer compatibility issues.

Cross-Play Support

Farming Simulator 25 supports cross-play between PC, Xbox, and PlayStation, as long as everyone is on the same game version and you use cross-play compatible content.

What You Should Know:

• Console players are limited to in-game ModHub mods, so mixed-platform servers should stick to ModHub content for hassle-free joining.
• PC players can add third-party mods, but these don’t sync to consoles.
• Check that your host explicitly supports cross-play before launch.

If you plan a mixed-platform community, stick with ModHub-approved mods to ensure stable cross-play for everyone.

Advanced Path A: Windows Automation (recommended)

Keep FS25 updated via Steam, Epic, or the GIANTS installer, then automate restarts and backups using Task Scheduler. 

 Automate:

• Nightly restarts (low-traffic hours)
• Weekly backups (savegame + dedicated_server folder)
• Optional: a startup task to relaunch dedicatedServer.exe after reboot

This avoids common “not activated” and update-flow issues that can occur when running FS25 as a SteamCMD-only dedicated package.

Why This Matters

Automated updates keep your server world stable and secure while you sleep. But skipping the activation check often results in downtime and player complaints. Many guides assume fully headless update flows. In practice, do one clean update + restart cycle, then verify the save loads before players join.

Advanced Path B: Linux/WINE or Community Containers (use with care)

Let’s take a look at running your Farming Simulator 25 dedicated server on Linux via WINE or Docker containers, workable but with serious caveats.

What Works & What Doesn’t

What works:

• Some community projects (e.g., wine-gameservers/arch-fs25server on GitHub) provide a Docker image with FS25 under WINE.
• The Linux setup can reduce resource overhead compared to full Windows installs if you already maintain a Linux host.
• You can automate deployment, updates, and backups using containers and scripts.

What doesn’t work reliably:

• Official documentation states that only the Windows OS is suitable for a dedicated FS25 server.
• WINE setups often require tinkering, encounter bugs, and may break after FS updates.
• Some features or services (game client activation, license validation, DLC entitlement checks, and mod integrity) may assume a Windows environment and can fail or glitch under WINE.
• Community support is thin; major hosts do not guarantee Linux server compatibility.

Advice for Admins

• Use Linux/WINE hosting only if you are comfortable diagnosing launch errors, path issues, version mismatches, and can commit spare time to fixes.
• For production servers (public, many players, uptime guarantee), prefer Windows hosting.
• If you proceed with Linux/WINE, maintain backups, test updates in a staging instance, keep your WINE version/thread versions documented, and expect some manual intervention after patches.

Performance Tuning & Maintenance (for Bigger Maps & Communities)

Here is how you can keep your Farming Simulator 25 dedicated server smooth, stable, and ready for large multiplayer worlds.

Prioritize High-Clock CPUs

• FS25’s dedicated server is single-thread-sensitive for the main simulation loop, so clock speed matters more than core count; extra cores are still useful for headroom (mods/IO/OS) or hosting multiple servers on one machine.
• Choose CPUs like Ryzen 9, Intel Core i9, or modern Xeon Gold with 4.5 GHz + boost.
• In practice, higher per-core performance usually improves simulation consistency, especially with heavy mods and large maps.
• If the host runs other services, keep CPU headroom available and avoid background workloads that steal sustained CPU time.

Use SSD/NVMe Storage for Faster Syncs

• Large maps and mods generate intensive read/write operations.
• SSD or NVMe drives drastically cut load times and savegame delays.
• HDDs cause bottlenecks, especially during autosaves and map transitions.
• For mod-heavy setups or cross-platform Farming Simulator 25 dedicated server hosting, NVMe is a must.

Manage Savegame Size & Restarts

• While there is no official size cap, many server admins report noticeable performance impact once save folders exceed 2-4 GB, depending on mods and hardware.
• Schedule daily or nightly restarts during off-hours to clear RAM and maintain tick stability.
• Use Windows Task Scheduler scripts for automatic reboots on your Farming Simulator 25 dedicated server setup.
• Restart cycles help prevent lag spikes on long-running servers.

Monitor Usage & Control Heavy Mods

• Track CPU, RAM, and network usage with Resource Monitor, Grafana, or Zabbix.
• Disable newly added or unoptimized mods when you notice lag or desync.
• Limit your mod list to official ModHub or verified community mods for consistent performance.
• Heavy or faulty mods are a leading cause of multiplayer stutter and server desyncs.

Backups, Patching & Maintenance Cycle

A stable farming simulator 25 dedicated server requires consistent upkeep:

• Back up your savegame folder and …\Documents\My Games\FarmingSimulator2025\dedicated_server\ weekly.
• Store copies in the cloud or external storage.
• Apply OS patches and game updates during off-peak hours.
• Keep a simple change log of mod updates or configuration edits.

 If a patch causes issues, you can instantly roll back without losing player progress.

Migration, Updates & Backup Automation

Let’s minimize downtime and data loss on your Farming Simulator 25 dedicated server with smart migration, update routines, and backups.

Migrating from Earlier Worlds

• If you upgrade from FS22 or move between hosting setups, test the world first in a sandbox.
• If the savegame shows loading errors or weird physics, start a fresh savegame and archive the old one.
• Copy your savegameX folder and dedicatedServer.xml to the new server path, then launch once to confirm compatibility.
• Rename the old world folder to include date and version, for rollback safety.

Scheduled Windows Tasks for Automation

Set up three key scheduled tasks using the Task Scheduler on your server machine:

• Nightly restart at 02:00:

@echo off

echo Stopping FS25 Server…

REM WARNING: Don’t restart during autosave. Schedule restarts when the server is empty.

taskkill /IM dedicatedServer.exe /F

timeout /t 10 /nobreak

echo Starting FS25 Server…

cd “C:\Program Files (x86)\Farming Simulator 25\”

start “” dedicatedServer.exe

echo Restart complete.

• Weekly backup every Sunday at 03:00:
  • Action: batch script that zips …\Documents\My Games\FarmingSimulator2025\savegame* and dedicatedServer.xml, then uploads to cloud or external drive.
• Monthly mod audit on the first of each month:
  • Action: Launch script to compare mod folder against baseline list, email differences, and flag legacy mods.

Update Flow & Post-Update Validation

• Apply updates via Steam/Epic/GIANTS installer (or your host’s update tool):
• After the update, restart the server; check the log files for errors, especially mod load failures or mismatches.
• Run through this checklist:
  • The server shows “activated” in the web panel.
  • Savegame loads without errors.
  • Mods enabled and version numbers match.
  • Player slot tests: join via private IP and public server list.
  • Monitor the first 30 minutes of gameplay for spikes in CPU/RAM/disk.

FAQs

Q.  How do I set up a Farming Simulator 25 dedicated server on Windows?

To install and run an FS25 dedicated server, you’ll need a licensed copy of the game on a Windows 10/11 PC or a Windows Server 2019/2022 system.

• Install and activate the game once on the host PC to bind your license.
• Locate the configuration file in:
  Find dedicatedServer.xml in your FS25 installation folder (same directory as dedicatedServer.exe).
• Edit this file with your server name, passwords, and slots.
• Launch dedicatedServer.exe as Administrator.
• Access the admin dashboard in your browser at https://localhost:8443 to control maps, mods, and players.

Q. Do I need a second game license to host a dedicated server in FS25?

Yes. You must own a separate Farming Simulator 25 license for the dedicated server.
The game’s licensing system doesn’t allow a single key to be used for both hosting and playing simultaneously.

You can purchase the extra license from Steam, Epic Games, or the GIANTS eShop. Once installed, launch the game once on the host to register the license before running the server in headless mode.

Q. Which ports must be opened for a Farming Simulator 25 dedicated server?

FS25 uses specific ports to allow player connections and admin access:

• Game traffic: UDP 10823, 10824, 10825
• Web admin panel: HTTP 8080 and HTTPS 8443 (prefer HTTPS)
• Web admin (HTTP): Port 8080 (avoid exposing publicly; use VPN/IP allow-list).

Forward UDP 10823, 10824, 10825 on your router to your server’s internal IP address. Allow inbound/outbound access for dedicatedServer.exe in Windows Firewall. Keep 8080/8443 private, only accessible via VPN or trusted IPs, because it provides full server control.

Q. Can I run a Farming Simulator 25 dedicated server on Linux?

Officially, FS25 supports Windows only for its dedicated server software. You can technically run the game using WINE or Docker containers on Linux, but those setups are unofficial and often break after updates. For reliability and full support, host on Windows or a Windows-based bare-metal server.

Q. How do I fix my FS25 dedicated server not showing up in the multiplayer list?

 If your server isn’t visible in the public list, check these steps:

• Ensure UDP ports 10823, 10824, and 10825 are open and forwarded correctly.
• Confirm the server and players are on the same game version. Update using Steam/Epic/GIANTS updater, then restart the server.
• Verify the server has a unique name and correct region in dedicatedServer.xml.
• Disable any firewall, antivirus, or VPN software blocking outbound traffic.
• Check for mod mismatches or corrupted savegame data.

After applying fixes, restart the server and wait about one to two minutes, GIANTS’ backend takes time to list new public servers.
