* Add username and password of client. Private key password I believe is the same password just added but I am not certain. (This is where having tested in windows is a good idea in case it doesn't work you can debug confidently).

* Add username and password of client, then you have to give the path of the '''user.p12''' key of your user and set the  Private key password (the password set during the key creation in phpky). After that you have to select the 'advanced' panel and go to 'TLS authentication'. Enable the use of TLS authentication, give the path or your '''takey.pem''' and select the key direction to 1.

* As a note, when connected successfully to the vpn, browsing the internet may not work in tandem, therefore go to '''ipv4 settings''' tab when editing the vpn connection. Click on "Routes" and check "Use this connection only for resources on its network". Also try adding 8.8.4.4 to "Additional DNS Servers" (This is google's dns servers).
