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

Decided to play Heroes 3 online with a friend, but we encountered some problems...
We both installed Hamachi, then connected to each other through Hamachi.
When we launch Heroes (both have Platinum Editions), we select "Network Game," then "TCP/IP," but we can't connect...
It gives an error saying that you can't connect to the current session, try again later. Also, after that, it immediately gives an error about an incorrect password (although we are entering the correct password).

What's the problem, and how can we fix it?
Thanks in advance.

The game is being blocked by the firewall or antivirus. In my case, the Wi-Fi adapter, which had its own firewall built in, was blocking it.

Regarding GameRanger: I downloaded it and tried playing with two other people, but the game just closed when connecting to a player. It seems that GameRanger, like GameSpy, is designed for direct IP addresses (I don't have a direct IP).
