After starting my kali Linux (previously know as Backtrack) my VPN add button is grey out and I am not able to add IPSec VPN connection to ASA gateway.
By running commands below in terminal VPN option become available:
apt-get update
apt-get install network-manager-openvpn network-manager-pptp network-manager-pptp-gnome network-manager-vpnc network-manager-vpnc-gnome
