Hi evryone sorry for the post even if many other people made a subject about this i didn't find a solution to my problem.

i wan't to play to mhfu with my friends . So we downloaded hamachi i created an hamachi server and i took my hamachi ip putted it in the adresse ip of server ad hoc of ppsspp and i ticked activate the serveur ad hoc integrated.
If I do that i can't even connect , when i want to go in the online hall the game freeze and it says connection error . however if my friend host , with his ip , he can go in the online hall , but i , still can't what is the issue???
