--
-- 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.
--
-- /Important:/ 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.
--
-- This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.
--
-- For more information, see <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html AWS Managed VPN Connections> in the /Amazon Virtual Private Cloud User Guide/ .
