fornellas / OpenVPN with shared HTTPS port
Last active May 13, 2016 20:43
This is a simple OpenVPN setup, with shared HTTPS port. To set up your own Certificate Authority, the easiest way is to follow: https://openvpn.net/index.php/open-source/documentation/howto.html#pki.
Once everything is set up, distribute client.ovpn + client's crt + client's key to each client and everything should work.
