The other reason to use OpenVPN is to protect yourself when you use public WiFi networks from Session hijacking. It protects you from brute-force attach by just not accepting clients with invalid certificates and it does not allow to perform Man-in-the-middle attack, because your client always will verify server certificate (just make sure to keep your keys in safe place). So what you can do for that? You can use OpenVPN.

This solution is not very secure, because somebody can attack you in two different ways: brute-force your password or use Man-in-the-middle attack. After that you have an option to make some ports available for public access, like Remote Desktop, ssh and VNC server and just protect these services by password.
