Point to Point VPN on a NAT environment?
I was wondering, is there any way to make a point-to-point VPN connection between 2 NAT connection? One would be my LTE and another will be my friend's dormitory internet, which I obviously don't have access to the router's settings. Having a kind of authentication server is fine as long as the actual traffic doesn't pass through it. Does anyone know any solution to this?
Thanks in advance!
