// Associates Elastic IP addresses (EIPs) and private IPv4 addresses with a public
// NAT gateway. For more information, see Work with NAT gateways (https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html#nat-gateway-working-with)
// in the Amazon VPC User Guide. By default, you can associate up to 2 Elastic IP
// addresses per public NAT gateway. You can increase the limit by requesting a
// quota adjustment. For more information, see Elastic IP address quotas (https://docs.aws.amazon.com/vpc/latest/userguide/amazon-vpc-limits.html#vpc-limits-eips)
// in the Amazon VPC User Guide. When you associate an EIP or secondary EIPs with a
// public NAT gateway, the network border group of the EIPs must match the network
// border group of the Availability Zone (AZ) that the public NAT gateway is in. If
// it's not the same, the EIP will fail to associate. You can see the network
// border group for the subnet's AZ by viewing the details of the subnet.
// Similarly, you can view the network border group of an EIP by viewing the
// details of the EIP address. For more information about network border groups and
// EIPs, see Allocate an Elastic IP address (https://docs.aws.amazon.com/vpc/latest/userguide/vpc-eips.html#allocate-eip)
// in the Amazon VPC User Guide.
