A NAT service plan consists of bandwidth resources and one or more public IP addresses. When you use a NAT service plan, you are charged a rental fee for the public IP address and a data transfer fee.
The billing methods
NAT service plans are billed on a pay-as-you-go basis. You are charged and billed on an hourly basis. If you use a NAT service plan for less than one hour within a billing cycle, the usage duration is rounded up to one hour.
Public IP address rental fee = Unit price × Number of public IP addresses × Rental period
Data transfer fee = Unit price × Volume of outbound data transfer
You are charged only for outbound data transfer (from Alibaba Cloud to the Internet). You are not charged for inbound data transfer.
The unit price for outbound data transfer is fixed and does not vary with the bandwidth limit of the NAT service plan. We recommend that you set the bandwidth limit based on your service requirements. This helps you prevent unnecessary costs that may be caused by malicious requests or service malfunction.
