Port Forwarding HELP!!!

[LuGabbiano]

Hi,
i'm using hamachi at the moment to make my minecraft server but more than 1 friend can't join my private network, otherwise it won't work for anyone, but i keep having problems with hamachi even if it's just me and one my friends connected. So i tried to portforward but it says '' no connection'' even when i try to join.
Can anyone help me please?

the problem is that, since i live in italy my modem model isn't on the list and has a different router to other one's.
It's a sitecom 300n WLM-3500 and these are some images of the router page:

remove virtual server and trigger port and see how it does
your internet connection speed linking the mc server might not have enough bandwidth to support more than you
also the mc server hardware spec can be low to support all the people you need
