This happens with various games, from Battlefield 2 to Trackmania and therefore seems to be some network configuration error:
When anyone else hosts a LAN game I am the only one that can't see their server in the in-game server browser, nor can I join it with a direct IP connection. However, when I host the game everyone else is capable of joining my server without any problems. I am also the only one on the network experiencing these issues.
Things I already checked:
- Windows Firewall is set to allow each application (and the problem still happens when it is completely disabled)
- Other networking an internet programs like browsers, e-mail, ssh and ftp are working perfectly fine
- Various static/dynamic IP address/subnet mask and default gateway settings don't fix the problem
