Hamachi and Portforwarding Alternative(s)?

Hi,
I'm trying to look for an alternative solution for portforwarding and hamachi.
An alternative that can let users connect with no clients, if possible.
Thanks!

well they should use magic i guess.

 

Users who connect to a server do not need to forward ports, nor use an external application such as hamachi.
ONLY the server HOST needs to forward the port(default is 25565).
There is NO other way to allow users to connect to a server unless the IP/Port are Public. Port forwarding is what makes that port public.
The use of Hamachi bypasses this necessity, by allowing users to be in your virtual "local area network" - in which case all ports are accessible, as it's a private network, not a public one.
