Create a new folder in your home dir - I called mine vpn.config

Copy your downloaded client.ovpn file into the new folder



Open client.opvn in an editor



Open a new file

Cut the lines between <ca> tags in client.ovpn

Paste into new file, save this file as ca.crt

Remove both <ca> tags from client.ovpn



Open a new file

Cut the lines between <cert> tags in client.ovpn

Paste into new file, save this file as client.crt

Remove both <cert> tags from client.ovpn



Open a new file

Cut the lines between <key> tags in client.ovpn

Paste into new file, save this file as client.key

Remove both <key> tags from client.ovpn



Open a new file - this is the last one :-)

Cut the lines between <tls-auth> tags in client.ovpn

Paste into new file, save this file as ta.key

Remove both <tls-auth> tags from client.ovpn



And remove this line:

key-direction 1





Now position the cursor in client.ovpn, right above the line # -----BEGIN RSA SIGNATURE-----



Insert the following lines



ca ca.crt

cert client.crt

key client.key

tls-auth ta.key 1



Save and close all the files.



Goto Network Manager -> Edit Connections ->VPN

click Import, browse to the modified client.ovpn in the folder you recently created - and where your certificates are, and import that file

Enter vpn username and password if prompted

On the VPN page, select Advanced

On the General Tab, uncheck the first option, "Use custom gateway"



Save



Use...
