Early attempts to play CoH2 "on LAN" utilized Virtual LAN (VLAN) software like Hamachi, Tunngle, or Evolve. These tools created a virtual network adapter that tricked the operating system into thinking remote computers were on a local network. However, because CoH2 still queried the Steam API for authentication, players still had to be logged into Steam, and traffic was often still routed through Steam's backend regardless of the virtual adapter.

Technically speaking, the process of a LAN match in CoH2 follows these steps:
Relic Entertainment migrated the game from Google Servers to Amazon Web Services (AWS) servers to preserve online matchmaking infrastructure.
Run the game executable directly as an administrator (do not open Steam). Navigate to the custom match screen. Early attempts to play CoH2 "on LAN" utilized
Although the game is in offline mode, it may still allow you to see other players on the same local subnet if you are using a router.
Whether you’re setting up a dorm tournament, a garage LAN party, or just want to play offline with your buddy on the same Wi-Fi, this guide covers everything you need—including recent updates, common “LAN upd” errors, and the best workarounds.
Once the match begins, the Steam backend hands off packet distribution directly to your local router via UDP, resulting in a lag-free environment. Every participant must own a distinct copy of the game
A key development to watch is the possible closure of the old Quazal servers that CoH 2 relies on. Those servers have been in operation for many years, and their eventual shutdown could force Relic to implement true LAN support as a fallback. For now, however, the game continues to work as designed.
Some iterations of the LAN update are distributed as a mod via the in-game modding platform (powered by Relic's Attribute Editor). While the mod tools cannot alter the game engine's networking code, they can alter game rules and UI elements to support community-run dedicated servers, which act as a pseudo-LAN hub.
