connection employed the L2TP without IPSec policy can be
viewed as one pure L2TP connection.
Nice to Have - Apply the IPSec policy first, if it is applicable
during negotiation. Otherwise, the dial-in VPN connection
becomes one pure L2TP connection.
Must - Specify the IPSec policy to be definitely applied on
the L2TP connection.
You can specify the IP address of the remote dial-in user or

without IPSec policy above.
