Properties


Property	Type	Required	Editable	Description	Constraint
Description	String	No	No	The description of the NAT gateway.	The description must be 2 to 256 characters in length and cannot start with `http://` or `https://`.
NatGatewayName	String	No	No	The name of the NAT gateway.	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://`. If you do not specify this parameter, the ID of the gateway is used as the gateway name.
InstanceChargeType	String	No	No	The billing method of the NAT gateway.	Default value: PostPaid. Valid values: PostPaid: pay-as-you-go PrePaid: subscription
PricingCycle	String	No	No	The billing cycle of subscription NAT gateways.	Default value: Month. Valid values: Month Year This parameter is required when InstanceChargeType is set to PrePaid.
VSwitchId	String	Yes	No	The ID of the vSwitch to which the NAT gateway is attached.	When you create an enhanced NAT gateway, you must specify a vSwitch for the gateway. Then, the system assigns an available private IP address from the vSwitch to the gateway. To create an enhanced NAT gateway attached to an existing vSwitch, make sure that the zone to which the vSwitch belongs supports enhanced NAT gateways. In addition, the vSwitch must have available private IP addresses. If you do not have a vSwitch in the specified VPC, create a vSwitch in the zone that supports enhanced NAT gateways. Then, specify the vSwitch for the enhanced NAT gateway. You can call the ListEnhanhcedNatGatewayAvailableZones operation to query zones that support enhanced NAT gateways. You can call the DescribeVSwitches operation to query the number of available private IP addresses in a vSwitch.
Duration	Number	No	No	The subscription period.	Valid values: Valid values when PricingCycle is set to Month: 1 to 9. Valid values when PricingCycle is set to Year: 1 to 3. This parameter is required when InstanceChargeType is set to PrePaid.
DeletionProtection	Boolean	No	No	Specifies whether to enable deletion protection.	Valid values: true false
InternetChargeType	String	No	No	The billing method for network usage of the NAT gateway.	Valid values: PayBySpec: The NAT gateway is billed on a pay-by-specification basis. PayByLcu: The NAT gateway is billed on a pay-by-LCU basis. Note To set InternetChargeType to PayByLcu, set NatType to Enhanced first. This setting is supported only in the following regions: China (Shanghai), China (Beijing), China (Zhangjiakou), China (Hohhot), China (Ulanqab), China (Heyuan), China (Chengdu), Singapore (Singapore), Malaysia (Kuala Lumpur), India (Mumbai), Indonesia (Jakarta), Germany (Frankfurt), and UK (London).
AutoPay	Boolean	No	No	Specifies whether to enable automatic payment.	Valid values: false: Automatic payment is disabled. After an order is generated, you must go to the Order Center to complete the payment. true: Automatic payment is enabled. Payments are automatically completed. When InstanceChargeType is set to PrePaid, you must specify this parameter. You do not need to specify this parameter when InstanceChargeType is set to PostPaid.
NatType	String	No	No	The type of the NAT gateway.	Valid values: Normal: standard NAT gateway Enhanced: enhanced NAT gateway
DeletionForce	Boolean	No	No	Specifies whether to forcibly delete the NAT gateway.	Valid values: true: The system forcibly deletes the NAT gateway. false: The system does not forcibly delete the NAT gateway.
VpcId	String	Yes	No	The ID of the VPC in which to create the NAT gateway.	To create a standard NAT gateway, make sure that the route table of the VPC does not contain a route entry that has the destination CIDR block set to 0.0.0.0/0. If such a route entry exists, delete it. Note The preceding limit does not apply when you create an enhanced NAT gateway in a VPC.
Spec	String	No	No	The size of the NAT gateway.	Default value: Small. Valid values: Small Middle Large XLarge.1
Tags	List	No	No	The list of one or more tags of the NAT gateway.	A maximum of 20 tags can be bound to the NAT gateway. For more information, see Tags properties.

  {
    "Key": String,

Tags properties


Property	Type	Required	Editable	Description	Constraint
Key	String	Yes	No	The key of the tag.	The tag key must be 1 to 64 characters in length and cannot contain `http://` or `https://`. It cannot start with `acs:` or `aliyun`. The tag key can contain letters, digits, periods (.), underscores (_), and hyphens (-).
Value	String	No	No	The value of the tag.	The tag value can be 0 to 128 characters in length and cannot contain `http://` or `https://`. It cannot start with `acs:` or `aliyun`. The tag value can contain letters, digits, periods (.), underscores (_), and hyphens (-).
