: Both players must launch Anno 1800 while online and connected to matchmaking. Host a Match : One player goes to the Multiplayer , and then chooses Host New Game Invite Players icon (PC) or

(Console) under your name to invite your friend via their Ubisoft Connect name. If you enable the "Friend Game"

Step 1: Ensure Game Versions Match

All players must have the same game version and the same set of DLCs enabled. Mismatched DLC will make the lobby incompatible. The host’s DLC selection determines what everyone plays with. does not support native offline LAN multiplayer or

Step 3: The "Direct Link" Bypass (For tricky networks)

If the game does not appear in the lobby list despite being on the same switch, you can use the Ubisoft Connect overlay to force the link:

1. Host starts the lobby and waits in the "Waiting for players" screen.
2. Host presses Shift + F2 to open Ubisoft Connect overlay.
3. Host opens Friends list, right-clicks the friend’s name, selects "Invite to Game."
4. Client accepts via the notification popup.
   • Why this works: The invite system uses the Ubisoft peer-to-peer protocol, which will attempt a direct UDP hole punch to the local IP first before failing over to the relay.

Common connectivity problems & fixes

• Different game versions/updates: ensure all clients match versions and DLC.
• Firewall/antivirus blocking: allow Anno 1800 and Ubisoft Connect through Windows Firewall on all machines.
• NAT or router isolation: disable AP/client isolation on Wi‑Fi routers (prevents devices from seeing each other).
• Ubisoft Connect offline or account issues: sign out/in, restart the client, or verify server status.
• High latency or packet loss: prefer wired connections; check local network health.

Procedure

Step 1: Offline-first preparation
Launch Ubisoft Connect on each PC, log in, then go offline (click your avatar → Go Offline). Note: You must have logged in online at least once on that PC before.

Step 2: Launch Anno 1800
Start the game. It will complain about being offline – ignore it. You can still host/join LAN games.

Step 3: Host creates the game

• Multiplayer → New Game → Set slots to "Local Network" (not "Internet").
• Choose settings, DLCs, then Start Game.
• Once loaded, the host sees a "Server IP" on the pause screen (e.g., 192.168.1.100).

Step 4: Join via direct IP (most reliable)
On client PCs: Host starts the lobby and waits in the

• Multiplayer → Join Game → Switch to LAN tab.
• If the game doesn't appear automatically, click Direct IP and enter the host’s local IP address.

Step 5: Verify LAN traffic
On the host PC, open Command Prompt as admin and run:
netstat -an | findstr "18000"
You should see UDP 192.168.x.x:18000 ESTABLISHED with the client’s IP.

Co-op Mode: The Best LAN Experience

If you have a friend on the same network, Co-op mode is where LAN truly shines. In co-op, two or more players control the same company. You can split responsibilities:

• One player manages production chains and trade routes.
• Another handles expeditions, diplomacy, and military.
• A third focuses on city layout and beauty building.

Because there is no network lag over LAN, co-op feels nearly seamless. You can both pause, build, and issue commands simultaneously. It’s an excellent way to teach a new player or tackle a massive empire together.

Problem 1: The UPnP (Universal Plug and Play) Trap

Anno 1800 tries to use UPnP to forward ports on your router. On a LAN, you don't want this. Disable UPnP on your router for the duration of the LAN party. This forces the game to use raw local sockets.
