When trying to play Medieval II: Total War multiplayer in LAN mode, you may encounter the problem that the players can’t see each other in the lobby and can’t find the hosted game despite of correct versions, network configuration and firewall settings.

There is a quite easy fix for this problem, just follow the steps below:

1. Browse to the directory containing Medieval II (e.g. C:\Program Files\Medieval II Total War)
2. Open medieval2.preference.cfg with notepad
3. Scroll down to the [network] section and edit the following line saying “use_ip = “. Put your LAN IP address after the equals sign and save the file
4. Restart the game, now everything should work nicely!

If there are any other issues, please comment and I will try to help!
