Connecting to a VPN Service like Torguard or SlickVPN

Everything I come across involves setting up OpenVPN for access to OMV from outside the home network. How do I go about setting up OMV to connect to an outside VPN service? I'm looking to get away from BTGuard Proxy.

If you're talking about openvpn client you can just place your conf file At /etc/openvpn and start the daemon. Openvpn should pick the file from there and connect.

So it's not done through the plugin interface?
