Properties

Property	Type	Required	Editable	Description	Constraint
NatIpCidr	String	Yes	No	The NAT CIDR block that you want to create.	The NAT CIDR block must meet the following conditions: The NAT CIDR block must fall within one of the following CIDR blocks or their subnets: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. The subnet mask of the NAT CIDR block must be 16 to 32 bits in length. The NAT CIDR block cannot overlap with the private CIDR block of the virtual private cloud (VPC) to which the VPC NAT gateway belongs. If you want to use other IP addresses from the private CIDR block of the VPC to provide NAT services, create a vSwitch within the VPC CIDR block and attach the vSwitch to another VPC NAT gateway. If you want to use public IP addresses to provide NAT services, make sure that the public IP addresses fall within a customer CIDR block of the VPC to which the VPC NAT gateway belongs. For more information about customer CIDR blocks, see VPC FAQ.
NatIpCidrDescription	String	Yes	Yes	The description of the NAT CIDR block.	The description must be 2 to 256 characters in length. It must start with a letter and cannot start with `http://` or `https://`.
NatIpCidrName	String	Yes	Yes	The name of the NAT CIDR block.	The name must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). It must start with a letter and cannot start with `http://` or `https://`.
NatGatewayId	String	Yes	No	The ID of the VPC NAT gateway with which you want to associate the NAT CIDR block.	None.

Return values

Fn::GetAtt

NatIpCidrId: the ID of the created NAT CIDR block.
