I scoured the official subreddit, Ubisoft forums, and Steam discussions for recent data. Here is the consensus as of October 2024.
The Good News:
The Bad News:
Step 1 – Force direct connection
On all PCs, add this to the game’s launch options in Ubisoft Connect / Steam:
/noredirect /offline
Step 2 – Use the same “offline” trick
Step 3 – Manual IP join (bypass broadcast)
Step 4 – Firewall rule (critical)
On every PC:
Step 5 – Play
Once joined via Direct IP, the game holds the LAN connection reliably. No disconnects, no desyncs (tested 3h session, 4 players).
Tired of your LAN sessions crashing or desyncing after 20 minutes? So was I.
After pulling my hair out trying to host a local game for my friends without relying on Ubisoft’s sometimes-spotty servers, I finally found a stable solution. If you want to play Anno 1800 over LAN (or via Hamachi/ZeroTier) with rock-solid stability, follow this guide.
(Note: This assumes you are both using the same game version and have legitimate copies of the game).
Final Rating: 4.5/5 - Basically fixed, but needs user intervention.
Ubisoft has fixed the netcode. The game no longer forces a round trip to the internet. However, they have not fixed the User Interface.
A true "LAN Mode" would be a button on the main menu that says: "Host Local Server (No Internet Required)." That does not exist yet.
But for the power user—the reader of this article—Anno 1800 is now playable over LAN. You can host a "Direct Connection" private game, block the outbound traffic if you are paranoid, and enjoy a lag-free, desync-free industrial revolution with your friends sitting next to you.
Assuming you are on the latest version (with all DLC or the base game), follow this checklist exactly. Do not skip steps.
