Company of Heroes 2 LAN Update Guide

Introduction

Company of Heroes 2 is a real-time strategy game developed by Relic Entertainment. While the game has an active online community, playing with friends over LAN (Local Area Network) can be a great way to enjoy the game together. However, setting up a LAN game can be a bit tricky, especially with the game's built-in online features. In this guide, we'll walk you through the steps to update and play Company of Heroes 2 over LAN.

Prerequisites

  • Company of Heroes 2 game installed on all machines
  • A working LAN connection between machines
  • All machines must be on the same network

Step 1: Update the Game

  1. Launch the game on one machine and check for updates. The game will automatically download and install any available patches.
  2. Once updated, note down the game version number (e.g., v4.2.0).

Step 2: Disable Online Features

To play over LAN, you'll need to disable the game's online features. This will prevent the game from trying to connect to the internet and interfere with your LAN game.

  1. On each machine, go to Options > Game Settings.
  2. Under Game, uncheck Enable Online Features.
  3. Under Multiplayer, set Game Type to LAN.

Step 3: Configure Network Settings

  1. Ensure that all machines are on the same network and can ping each other. You can test this by opening a Command Prompt (Windows) or Terminal (Mac/Linux) and typing ping <machine IP address>.
  2. Take note of each machine's IP address. You'll need these addresses to set up the LAN game.

Step 4: Create a LAN Game

  1. On the machine that will be hosting the game (the Server), launch the game and select Multiplayer > Create Game.
  2. Choose a game mode (e.g., Conquest) and map.
  3. Under Game Settings, set Game Type to LAN.
  4. Note down the Game Port number (e.g., 7946).

Step 5: Join the LAN Game

  1. On each client machine, launch the game and select Multiplayer > Join Game.
  2. Enter the Server machine's IP address and Game Port number (e.g., <server IP address>:7946>).
  3. Click Join to connect to the game.

Common Issues and Solutions

  • Unable to connect to LAN game: Ensure that all machines are on the same network, and the game port is open on the server machine's firewall.
  • Game not showing up in LAN game list: Verify that all machines have the same game version and that the server machine is hosting the game with the correct game type (LAN).

Tips and Tricks

  • Make sure all machines have the same game version to avoid compatibility issues.
  • Use a third-party tool like Hamachi or Tunngle to simplify LAN gaming and overcome network limitations.
  • Consider setting up a dedicated server for a more stable and lag-free experience.

By following these steps and troubleshooting common issues, you should be able to set up and play Company of Heroes 2 over LAN with your friends. Happy gaming!

In Company of Heroes 2 (CoH2) , there is no native LAN feature. Since its release, the game has relied entirely on Steam and Relic's BattleServer for all multiplayer functionality. Unlike the original Company of Heroes, which supported LAN play, CoH2 requires an active internet connection to log into the servers even for "Custom Games". Best Options for a "LAN-style" Experience

If you are planning a local session with friends, you have a few ways to make it work:

Custom Online Lobbies: This is the standard way to play locally. Everyone connects to the internet via Steam, and you host a Custom Game.

Requirements: Each player needs their own copy of the game and an active internet connection.

Private Matches: You can password-protect your lobby or manually invite friends from your Steam list.

The "Internet Pull" Workaround: Some players have had success by logging into Steam and the Relic servers while online, then disconnecting the internet once everyone is in the lobby. This is reportedly finicky and may not work with the current 64-bit version of the game. company of heroes 2 lan upd

Switch to Company of Heroes 1 (Legacy): If a true offline LAN is your goal, the Legacy Version of CoH1 (Tales of Valor) is the only entry in the series that officially supports it.

Pro Tip: You can use tools like the Hamachi VPN to simulate a LAN over the internet if your group is in different locations but wants to use the old LAN menu. Troubleshooting Connectivity

If you're having trouble seeing each other in a shared local network:

Static IPs: Give each PC a separate, static IP address within your local network.

Port Forwarding: Ensure your router isn't blocking the game's traffic. Check the Relic Lobby Status to verify your connection to the game's master servers.

Company of Heroes 2 LAN Update: Enhancing Multiplayer Experience

Relic Entertainment and Sega have announced a significant update for Company of Heroes 2, focusing on enhancing the game's LAN (Local Area Network) multiplayer capabilities. This update aims to improve the overall gaming experience for players who prefer the immediacy and reliability of LAN play, especially in an era where online connectivity can sometimes be a hindrance.

Troubleshooting

  • Version mismatch: update all copies to the same patch.
  • Firewalls: allow the game in OS firewall and router settings.
  • NAT/Double NAT: LAN should avoid NAT issues; if joining across routers, port forwarding or VPN may be needed.
  • Desyncs: restart host and clients; verify mods are identical or disabled.
  • Mods: many LAN systems require identical mod lists—disable mods if problems persist.

Step 3: The "Network Interface Bridging" Fix (For physical LAN parties)

CoH2 hates multiple active network adapters (WiFi + Ethernet).

  • Fix: Disable WiFi on every machine when using a wired LAN switch.
  • Fix 2: If you must use WiFi, go to Control Panel → Network Connections → Press Alt → Advanced → Advanced Settings → Move your active LAN adapter to the top of the list.

4. Use Cases and Community Impact

The LAN update has found specific niches within the CoH2 community, extending the lifespan of the title in ways the developers perhaps did not anticipate. Company of Heroes 2 LAN Update Guide Introduction

4.1 Competitive Integrity In professional casting and tournaments, lag is a critical failure point. A "dropped" game due to Steam instability can ruin a tournament bracket. LAN updates allow tournament organizers to set up offline environments where players connect directly to a local host machine, ensuring stability and eliminating the "lag excuse."

4.2 Preservation and Longevity The "dead game" scenario is a fear for all online-dependent titles. If Valve or Relic were to shut down CoH2 master servers, the game would become unplayable. The LAN update serves as a preservation tool, ensuring that the game remains playable in perpetuity, independent of the publisher's server status.

4. The "Patch That Broke Everything" (Dec 2019)

A balance patch inadvertently blocked most virtual LAN adapters. The community reverse-engineered the fix within 48 hours: replacing the net DLLs with versions from an older build. Relic never commented.

Part 7: Why Relic Never Fixed This (And Why You Need This Guide)

Despite being a top-tier RTS, Company of Heroes 2 was designed during the height of "Always Online DRM." Relic assumed every player has a 50Mbps connection. For LAN tournaments (DreamHack, ESL), organizers have internal cache servers for Steam, but home users suffer.

The lan upd issue persists because the game uses Steam's P2P Lobby System, which still routes discovery packets through Valve's US Central servers. Yes, even for a PC two feet away.

Final verdict: For a flawless LAN experience, you are better off playing Company of Heroes 1 (Blitzkrieg mod) or waiting for Company of Heroes 3 which has rewound the netcode. However, by following the UDP port tricks and the Golden Build method above, you can force CoH2 to behave.

6. The Larger Lesson

CoH2 shows the tension between developer control and player ownership. LAN isn’t a technical limitation – it’s a business policy. And the community’s ingenuity proved that where there’s a will (and a packet sniffer), there’s a way.

Company of Heroes 2 LAN: Fixing the "UDP" Port Issue for Smooth Matches

If you are searching for "Company of Heroes 2 LAN UDP," you are likely trying to host or join a local area network game and running into connection issues. You might see errors like "Unable to connect," "Lobby no longer exists," or players timing out during loading.

The "UDP" in your search refers to User Datagram Protocol—a networking standard that CoH2 uses to send game data quickly. Unlike single-player, LAN mode requires specific UDP ports to be open on your firewall and router. Company of Heroes 2 game installed on all
