So I tried to play Defense of the Ancients (DotA – a Warcraft 3 mod) over Hamachi with some people only to find out that I couldn’t see the LAN game in the lobby. If you have this issue, try to see if you can telnet to port 6112 of the hoster’s IP address. If that works, you’ll get disconnected after a few return presses, you need to check if all Warcraft 3 versions are all the same. This was the issue I was running in. I had missed the latest patch (1.21b to 1.22a) back in July 2008.
