-- | 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 Adding a Hardware Virtual Private
-- Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.
