- How to play Heroes 3 online.

Could you please advise on how to configure a computer (Windows XP) for online gameplay? My friend and I want to play together. After several hours of experimentation, we managed to launch the game through Hamachi, but it requires the following steps: 1) Disable the network card connected to the internet in the network devices settings. 2) Launch the game and go to the TCP/IP menu. 3) Enable the network card. We set the priority for Hamachi. It would be fine, but it's very inconvenient, and the internet sometimes drops because Windows tries to connect directly through the Hamachi interface. Ideally, we want to play without using extra programs. We have our own VPN server (PPTP). Setting it up in Windows is not a problem, but the game refuses to recognize the IP address of the VPN connection. How can we make the game recognize the VPN?
