-- Creates a NAT gateway in the specified subnet. A NAT gateway can be used to enable instances in a private subnet to connect to the Internet. This action creates a network interface in the specified subnet with a private IP address from the IP address range of the subnet. For more information, see <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-nat-gateway.html NAT Gateways> in the /Amazon Virtual Private Cloud User Guide/.
