EHM The Blue Line

Hi, I need to know how to play NHL EHM 07 online. Both are connected to the network in hamachi. A friend created a game through the new network game but when I want to be connected enter its IP address but no go .. This same thing happens when I is based and he connect .. Please some guidance on how to play online

How many people do you want to play the game with?

Why are you using Hamachi? (sorry I am not familiar with it and we dont use any extra programs to run our EHM Online league)
