-- Creates a VPN connection between an existing virtual private gateway and
-- a VPN customer gateway. The only supported connection type is 'ipsec.1'.
--
-- The response includes information that you need to give to your network
-- administrator to configure your customer gateway.
--
-- We strongly recommend that you use HTTPS when calling this operation
-- because the response contains sensitive cryptographic information for
-- configuring your customer gateway.
--
-- If you decide to shut down your VPN connection for any reason and later
-- create a new VPN connection, you must reconfigure your customer gateway
-- with the new information returned from this call.
--
-- For more information about VPN connections, see
-- <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html Adding a Hardware Virtual Private Gateway to Your VPC>
-- in the /Amazon Virtual Private Cloud User Guide/.
