- How to play Heroes 3 online.

Please advise, what am I doing wrong? I have a computer and a laptop, the computer is connected to the router via cable, and the laptop is connected via Wi-Fi. I cannot see the created network game on either the computer or the laptop - it says "IP address does not exist." Both the computer and the laptop are on the same subnet, and I have disabled firewalls everywhere. I tried connecting via Hamachi and TeamViewer - the same thing happens. What could be the problem?
