Changes  Amazon Virtual Private Cloud (VPC) NAT Gateway adds support for tagging on resource creation.

CreateNatGateway (updated) Link ¶
Changes (request) 
{'DryRun': 'boolean'}

Creates a NAT gateway in the specified public subnet. This action creates a network interface in the specified subnet with a private IP address from the IP address range of the subnet. Internet-bound traffic from a private subnet can be routed to the NAT gateway, therefore enabling instances in the private subnet to connect to the internet. For more information, see NAT Gateways in the Amazon Virtual Private Cloud User Guide .
