Jouer en multijoueur sur Farming Simulator 2026 avec ses amis

Farming Simulator 2026 multiplayer depends entirely on how well you configure the server component GIANTS Software ships alongside the game. Savegame slots, the admin password, port forwarding and mod synchronisation all interact with each other, and a single misconfigured field is usually the reason friends can't join a shared farm. This guide walks through each setting, from the web interface down to the router.

How Farming Simulator 2026 multiplayer server settings fit together

Before touching any configuration file, it helps to understand the architecture behind Farming Simulator 2026 multiplayer. The game and the server are two separate executables. The server process loads your save, exposes a web interface for remote management, and listens on a network port that players connect to directly or through a farm code. Everything you configure — the save slot, the admin password, the open ports, the mod folder — feeds into that single running process.

That separation is useful because it means the server can keep running unattended while players come and go, and because the same save can be restarted after a crash without losing progress, provided backups are in place. If you'd rather skip the manual network tuning entirely, Fly-Serv provides Farming Simulator 2026 server hosting with the ports already opened and the web interface reachable out of the box, which is worth knowing before you spend an evening fighting a router.

For players who prefer running the save on infrastructure they control, the same logic described below also applies across our full lineup — see All our game servers for the other titles we support.

Configuring the web interface: savegame slots and the admin password

Accessing the web interface

The server exposes a browser-based control panel, typically on TCP port 8080 unless you changed it. Open http://<server-ip>:8080 from any machine on the same network, or from the public internet once the port is forwarded. The first login prompts you to set the administrator credentials — this is the password every co-op member will later use to claim admin rights inside the save, so pick it before you distribute it in a Discord channel.

Savegame slots explained

Farming Simulator 2026 keeps several independent savegame slots on the server, the same mechanism used in previous installments. Each slot stores its own map, finances, vehicles and placed buildings. When configuring multiplayer, confirm which slot number is loaded in the server settings before inviting anyone — launching the wrong slot is the single most common reason a fresh farm shows up empty for returning players.

Back up a slot before switching to another one, and before applying a mod update. The server's web interface usually exposes a manual save/backup action; use it right after a good session, not only on an automatic schedule.

Setting a strong admin password

The admin password grants full control over the save: kicking players, editing finances, adjusting difficulty, and restarting the process from the web interface. Treat it like an RCON password on any other game server:

• Use a unique password, not one reused from another title.
• Share it only with people who moderate the farm, not every participant.
• Rotate it if a member leaves the group on bad terms.

<Server>
  <Admin password="Ch4ngeTh1s!" />
  <SavegameSlot value="2" />
</Server>

This excerpt mirrors the structure of the dedicated configuration file the server reads on launch — the exact tag names can shift slightly between builds, so confirm against the current file generated in your install folder rather than copying it blindly.

Port forwarding for a shared Farming Simulator 2026 multiplayer save

Which ports the server needs

Two separate ports matter: the game port that clients connect through, and the TCP port serving the web interface. Both need to be reachable from the internet if you're running the server behind a home router.

Purpose	Protocol	Typical port
Game connection (clients join here)	UDP	2000
Web interface (remote management)	TCP	8080

These values can be adjusted inside the server settings, and GIANTS has changed defaults between releases in the past, so always verify the numbers shown in your own server's settings file against the official Farming Simulator website before opening anything on your firewall.

Forwarding ports on a home router

1. Assign the machine running the server a static local IP address.
2. Open your router's port forwarding section and map the external game port to that local IP on UDP.
3. Repeat for the web interface port on TCP, restricting the source range if your router supports it.
4. Test reachability from outside your network before inviting anyone — a mobile connection with Wi-Fi turned off works fine for this.

Opening ports when the server runs on a VPS you manage

If the server process lives on infrastructure like Linux VPS instead of a home connection, router configuration is replaced by a firewall on the machine itself:

sudo ufw allow 2000:2001/udp
sudo ufw allow 8080/tcp
sudo ufw reload
sudo ufw status

On a Windows machine, the equivalent is an inbound rule added through Windows Defender Firewall with Advanced Security for the same ports — relevant if your save runs on Windows VPS rather than Linux.

Mod synchronisation so every farmer loads the same content

Where mods must live

Mods used in a shared Farming Simulator 2026 multiplayer save must sit in the server's dedicated mod folder, not just in each player's personal mod folder. When a client connects, the server pushes any mod it's missing automatically — but only if the file is present server-side in the correct location and correctly named.

Keeping mod versions identical across all clients

Version mismatches are the leading cause of "mod synchronisation failed" messages. Naming conventions matter: a file like modName_v1.0.0.0.zip needs to match exactly between what the server distributes and what GIANTS' mod hub or Steam Workshop delivers to the client. If a player updates a mod locally ahead of the server, remove the outdated copy from the server folder and replace it rather than keeping both versions side by side.

Troubleshooting common synchronisation errors

• "Missing mod" on connect — the file isn't in the server's mod directory; copy it there and restart the process.
• Checksum mismatch — client and server versions of the same mod differ; delete both and re-download a matching pair.
• Mod loads on the server but crashes clients — check the mod's compatibility notes for the current game build before assuming a configuration mistake.
• Download stalls indefinitely — large mod packs over a slow upstream connection can time out; consider distributing bulky mods manually ahead of a session.

Keep a written list of the mod set approved for your farm, and review it any time someone proposes an addition. For more configuration walkthroughs across different titles, browse the Fly-Serv blog.

Getting a shared farm running smoothly comes down to a handful of settings handled correctly the first time: the right savegame slot, a strong admin password, both ports reachable, and a mod folder kept identical for every participant. Once those four pieces are in place, Farming Simulator 2026 multiplayer stays stable session after session.

FAQ

Why can't my friends connect even after forwarding the ports?

Double-check that the game port is forwarded as UDP, not TCP — this is the most common mistake. Also confirm the server's internal settings file still points to the same port you forwarded, since restarts can occasionally revert manual changes.

How many savegame slots can the server manage at once?

The server keeps several slots available, but only one loads at a time per running process. If you want two separate farms reachable simultaneously, you need two separate running server instances, each on its own ports.

Do all players need the exact same mod files to join?

Yes. The server pushes missing mods to connecting clients automatically, but version numbers must match exactly. Mismatched versions trigger a checksum error and block the connection until the files are synchronised.
