Enable port forwarding in your router's configuration to pass external connections to the internal machine. For example, forward TCP ports 5900 and 5800 to the machine's private IP (e.g., 192.168.1.100). Then connect to the router's IP using those ports.
TightVNC encrypts VNC passwords but sends other traffic unencrypted. For secure connections over the Internet, use SSH tunneling. Built-in encryption may be added in future versions.
