-- 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
