How to play Heroes of Might and Magic III online via Hamachi?

Situation at work :) In the game, half of the users are orange, so I'm trying to play through a group. The first connection works, meaning everything is fine until the restart. The second one doesn't... Moreover, before recreating the room, the game freezes on the loading screen. After recreating the room, a "direct play helper" error appears, and this time the opponent can't connect. And it's like that every time. What the heck is going on?) I checked the antivirus, but it didn't help.
