            This attribute exists to enable a Network Address Translation (NAT) instance in a VPC 
            to perform NAT. A value of true means checking is enabled, and false means checking is 
            disabled. The value must be false for the instance to perform NAT. For more information, 
            go to NAT Instances in the Amazon Virtual Private Cloud User Guide.
