When my friend logs on to the server Hamachi written (coneckting errore.The attempt to connect was bezuprechnoi because of another compuuter for there is no answer,or it was already broken osstanovlenie connections)

I can only suggest double checking the hamachi addresses. Hamachi should just work...

The better alternative is port forwarding though :)

This is not a DMP issue, it is your issue.
