To use port 443 as incoming for OpenVPN server, the port must be opened and/or forwarded.

A VPN connection is sequre. You ca increase sequre by tweaking encription from default. At this manual http://www.openvpn.net/index.php/open-s ... pn-21.html search TLS Mode Options and using options in there you can enforce connection.
