After Installing Debian 7 at Network Connections VPN add button is Disable.

After long search for the missing packages, I reinstall Debian 7.4 and install the next 3 packages, found in the  link HERE.

     sudo apt-get install network-manager-pptp

     sudo apt-get install network-manager-pptp-gnome

     sudo apt-get install pptp-linux

To support OpenVPN and be able to open “.ovpn” files install the followin packages:

     sudo apt-get install openvpn network-manager-openvpn network-manager-openvpn-gnome
