-- Creates a virtual private gateway. A virtual private gateway is the endpoint on the VPC side of your VPN connection. You can create a virtual private gateway before creating the VPC itself.

--
-- * 'cvgAmazonSideASN' - A private Autonomous System Number (ASN) for the Amazon side of a BGP session. If you're using a 16-bit ASN, it must be in the 64512 to 65534 range. If you're using a 32-bit ASN, it must be in the 4200000000 to 4294967294 range. Default: 64512
--
-- * 'cvgAvailabilityZone' - The Availability Zone for the virtual private gateway.
--
-- * 'cvgDryRun' - Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is @DryRunOperation@ . Otherwise, it is @UnauthorizedOperation@ .
--
-- * 'cvgType' - The type of VPN connection this virtual private gateway supports.
