You can convert an existing NAT Gateway bandwidth package to an EIP Bandwidth Plan instance. EIP Bandwidth Plan provides regional bandwidth sharing and reusing. You can add all Elastic IP addresses within the same region to the same EIP Bandwidth Plan instance. This enables you to share and reuse the bandwidth of the EIP Bandwidth Plan instance and save bandwidth costs.

Descriptions

During the conversion process, network connections are not interrupted and your online workload is not affected. After conversion:
  • The public IP addresses in the NAT Gateway bandwidth package are converted to Elastic IP addresses.
  • The NAT Gateway bandwidth package is converted to a common bandwidth package, which is easier to manage and more cost-effective.
  • If the conversion fails, you can continue to use the network services. If the problem persists, submit a ticket. When you submit the ticket, you must provide the following information:
    • Account ID or UID.
    • The request ID generated by Alibaba Cloud when you call the ConvertBandwidthPackage operation.
    • The instance ID of the NAT Gateway bandwidth package.
    • The screenshot of the conversion failure.

Prerequisites

Before you start the conversion, make sure that you have met the following requirements:

  • The NAT Gateway bandwidth package to be converted is under an account that has the required permissions.
    We recommend that you convert the NAT Gateway bandwidth package that is under an Alibaba Cloud account. If you want to convert the NAT Gateway bandwidth package as a RAM user account, before you start the conversion you must log on to the Resource Access Management console with your Alibaba Cloud account and grant the RAM user account the following permissions:
    • AliyunNATGatewayFullAccess
    • AliyunEIPFullAccess
    • AliyunCommonBandwidthPackageFullAccessAuthorization
  • Make sure that your account has a sufficient amount of Elastic IP addresses available.
    After the conversion, the public IP addresses in the NAT Gateway bandwidth package are converted to Elastic IP addresses. Make sure that the number of Elastic IP addresses is equal to or greater than that of public IP addresses in the NAT Gateway bandwidth package. In the Virtual Private Cloud (VPC) console, you can view the number of Elastic IP addresses on the Quota Management page. If the number of Elastic IP addresses is insufficient, you must apply for more Elastic IP addresses.The Quota Management page
  • Enable the whitelist feature for pay-by-traffic NAT Gateway bandwidth packages

    If the NAT Gateway bandwidth package to be converted is billed based on data usage, submit a ticket to apply for conversion.

  • Back up instance information

    Before you start the conversion, complete the following table based on the NAT Gateway instance information to track and confirm the conversion result.

    The instance ID of the NAT Gateway bandwidth package Region Bandwidth The number of IP addresses Conversion status The ID of the EIP Bandwidth Plan instance
    bwp-xxx1 China (Hangzhou) 200 Mbit/s 20 Successful cbwp-xxx1
    bwp-xxx2 China (Shanghai) 500 Mbit/s 50 Pending N/A

Procedure

After you have met all the preceding requirements, take the following steps to start the conversion:

  1. Apply for the conversion permission:
    1. Open the Quota Management page and click the Nat Gateway tab.
    2. Find natgw_privilege_allow_bwp_convert_cbwp and click Apply.
    3. Enter the reason for application and click OK.
    4. Wait one minute and click the Refresh icon to view the application status.
      This application is reviewed automatically. Permission Acquired indicates that the application has been approved.The Nat Gateway tab
  2. Call the ConvertBandwidthPackage operation to complete the conversion.
  3. Confirm the conversion result.
    You can view the ID of the EIP Bandwidth Plan instance to check whether the conversion is successful. The conversion rule of the instance ID is ${cbwpId}='c'+${bwpId}. For example, the instance ID of the NAT Gateway bandwidth package is ${bwpId}=bwp-e8caejcj. After the conversion, the ID of the EIP Bandwidth Plan instance is cbwp-e8caejcj.
  4. After the conversion, go to the Nat Gateway tab on the Quota Management page and apply for natgw_privilege_allow_bind_eip to associate converted Elastic IP addresses with the NAT Gateway. For more information, see Associate an EIP with a NAT Gateway.
