Element Description

The NAT.SNatRule element is used to create a source NAT rule, which specifies the network segment for accessing the external network.

Element Properties

**Table 1** Property Description
Property	Required	Descripiton
subnetId	Yes	ID of the Subnet to which the SNatRule belongs Type: HuaweiCloud.VPC.Subnet.Id Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: Use the get_input function to pass this parameter. Its value can then be automatically selected when you create a stack on the AOS console. Connect to a subnet object and use the get_reference function to the ID of the newly created subnet.
floatingIpId	Yes	User EIP ID Type: HuaweiCloud.VPC.EIP.Id Value Description: Supports the ID of an existing or new public elastic IP address. Suggestion: 1. Use the get_attribute function to obtain the ID of the elastic public IP address created by the template. 2. On the public elastic IP address page (https://console.huaweicloud.com/vpc?&locale=en-us), obtain the ID of the created IP address.
natGatewayId	Yes	ID of the NatGateWay Type: string Value Description: Obtains the natgateway ID from the NAT service or put snatrule in the natgateway to automatically establish the dependency relationship. Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: Use the get_input function to pass this parameter. Its value can then be automatically selected when you create a stack on the AOS console. Use the get_reference function to obtain the NatGateWay ID.
