I have one question , does stunnel work with NAT ? I will explain the architecture There are some 10.0.0.XXXX machines and some are 192.0.0.XXXX machines. They are connected to each other via Router which does NAT. My VNC servers are installed on 10.0.0.XXXX and vnc clients on 192.0.0.XXXX I am not able to do the vnc from client to server. Now I want to encrypt the VNC traffic , can stunnel work with NAT? A Kataoka
