Hello,

I have been trying to play HoMM 3 with my friends for a while now. We have a problem with the multiplayer functionality.

There have been 3 players so far, I'll call them A1, B2, and C3. We are using LogMeIn Hamachi to facilitate play.

When A1 hosts, B2 can join but C3 cannot.
This was later solved by adjusting Windows Firewall rules.
In which case, A1 hosts, B2 can join, and C3 can also join, but B2 cannot see C3's chat text. All other chat text is functional.
Upon playing a match, when B2 tries to end their turn, the game locks up for a few minutes, stuck at 80% of "sending data". A few minutes later, the game reports that there has been an error sending data. Clicking the Cancel button causes C3, whose turn would be next, to drop from the game, and be replaced by an AI.

Additional context information: A1 and B2 are on the same LAN, while C3 is connecting from a different network.

Is anyone having any issues, similar or not, with multiplayer? Can anyone help?
