nat_gateway_id	String	Specifies the NAT gateway ID.
port_id	String	Specifies the port ID of an ECS or a BMS.
private_ip	String	Specifies the private IP address, for example, the IP address of a Direct Connect connection.
internal_service_port	Integer	Specifies the port used by ECSs or BMSs to provide services for external systems.
floating_ip_id	String	Specifies the EIP ID.
floating_ip_address	String	Specifies the EIP.
external_service_port	Integer	Specifies the port for providing external services.
protocol	String	Specifies the protocol type. Currently, TCP, UDP, and ANY are supported. The protocol number of TCP, UDP, and ANY are 6, 17, and 0, respectively.
status	String	Specifies the status of the DNAT rule. For details about all its values, see Resource Status Description.
admin_state_up	Boolean	Specifies the unfrozen or frozen state. The value can be: true: indicates the unfrozen state. false: indicates the frozen state.
