Request Parameters Response Elements Errors See Also

AssociateNatGatewayAddress

Associates Elastic IP addresses (EIPs) and private IPv4 addresses with a public NAT gateway. For more information, see Work with NAT gateways 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 in the Amazon VPC User Guide.

Important

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 in the Amazon VPC User Guide.
