After you create a NAT gateway, you must purchase a NAT service plan for the NAT gateway. Then, you can configure Destination Network Address Translation (DNAT) or Source Network Address Translation (SNAT). Each NAT service plan consists of bandwidth resources and one or more public IP addresses.

Note If you want to associate an elastic IP address (EIP) with your NAT gateway, submit a ticket.
