@Mascasa recently wrote some excellent instructions on setting up OpenVPN using Amazon Web Services and getting connected with a Mac client:
It turns out connecting with Windows is easy too. Here’s how I did it…
- Download and install the OpenVPN GUI for Windows from here (the full Installation Package). Accept all the defaults when installing.
- Download the same keys and certificates used in the Mac setup (ca.crt, ta.key,yourname.crt and yourname.key) to your Windows machine. You might need a client like WinSCP to pull them off the EC2 server.
- Download the client template here and rename it to EC2_VPN.ovpn. Open it in WordPad and change the hostname and cert/key filenames (lines 42 and 89-90).
- Copy all of the files (.key, .crt and *.ovpn) to the OpenVPN configuration directory (usually \Program Files\OpenVPN\config).
- Right-click on the OpenVPN icon in the system tray and click Connect.
That’s it. Visit IPChicken and check that your Amazon IP appears. And leave a comment if you run into problems.
