Technical issues with Heroes III.

Hello everyone! Please help! I can't connect to Heroes through Hamachi. I've already tried everything. I connect to my friend through Hamachi, I can even ping him and access his computer. I connect to the internet through a Beeline modem. When I connect to my friend through Hamachi, I launch Heroes 3 Complete. I click on TCP\IP, and it shows me the IP address of the Beeline modem, not Hamachi! Therefore, I can't connect using either the Hamachi IP address or the Beeline IP address. :(( Please tell me how to make the Hamachi IP address the default. Thank you in advance!
