IPv6 gateways are used to control the IPv6 traffic of virtual private clouds (VPCs). After you create an IPv6 gateway, you can purchase IPv6 Internet bandwidth for the IPv6 gateway and create egress-only rules. This way, you can control the inbound and outbound IPv6 traffic of the VPC in a flexible manner.

Regions that support IPv6 gateways

The following regions support IPv6 gateways: China (Qingdao), China (Beijing), China (Zhangjiakou), China (Hohhot), China (Ulanqab), China (Hangzhou), China (Shanghai), China (Shenzhen), China (Heyuan), China (Guangzhou), China (Chengdu), China (Hong Kong), Philippines (Manila), Singapore (Singapore), US (Virginia), and Germany (Frankfurt).

IPv6 gateways of different editions

Alibaba Cloud provides different IPv6 gateway editions. When you use an IPv6 gateway to communicate with the Internet, the throughput capacity, the maximum bandwidth of each IPv6 address, and the maximum number of egress-only rules vary based on the edition. The following table describes the limits of each edition.
Edition Throughput capacity Maximum bandwidth of each IPv6 address Maximum number of egress-only rules
Pay-by-bandwidth Pay-by-data-transfer
Free Edition 10 Gbps 2 Gbps 200 Mbps 0
Enterprise Edition 20 Gbps 2 Gbps 500 Mbps 50
Enhanced Enterprise Edition 50 Gbps 2 Gbps 1 Gbps 200

Prerequisites

IPv6 is enabled for the VPC for which you want to create an IPv6 gateway. For more information, see Enable IPv6 for a VPC.

Create an IPv6 gateway

After you enable IPv6 for a VPC, the system automatically creates a Free Edition IPv6 gateway for the VPC. You can create IPv6 gateways of different editions based on your business requirements.

  1. Log on to the IPv6 Gateway console.
  2. On the IPv6 Gateway page, click Create IPv6 Gateway.
  3. On the IPv6 Gateway (Pay-As-You-Go) page, set the following parameters, click Buy Now, and then complete the payment.
    Parameter Description
    Region Select the region where you want to create the IPv6 gateway.

    The IPv6 gateway must belong to the same region as the VPC for which you want to create the IPv6 gateway.

    VPC ID Select the VPC for which you want to create an IPv6 gateway.
    A VPC may be unavailable in the drop-down list due to the following reasons:
    • An IPv6 gateway is created for the VPC. Only one IPv6 gateway can be created for each VPC.
    • The VPC has a custom route with the destination CIDR block ::/0. In this case, you must delete this custom route before you can create an IPv6 gateway for the VPC. For more information, see Delete a custom route.
    Note After an IPv6 gateway is created, you cannot change the VPC to which the IPv6 gateway is associated.
    Specification Select the edition of the IPv6 gateway. The following editions are available:
    • Free Edition
    • Enterprise Edition
    • Enhanced Enterprise Edition
    Billing Cycle IPv6 gateways are billed on a daily basis. For more information, see Billing.

Modify an IPv6 gateway

After you create an IPv6 gateway, you can modify the name and description of the IPv6 gateway.

  1. Log on to the IPv6 Gateway console.
  2. In the top navigation bar, select the region where the IPv6 gateway is deployed.
  3. On the IPv6 Gateway page, find the IPv6 gateway that you want to manage and click Manage in the Actions column.
  4. In the Information section, click Edit to change the name and description of the IPv6 gateway.
    modifyipv6

Delete an IPv6 gateway

If your VPC no longer needs to communicate with another network over IPv6, you can delete the IPv6 gateway of the VPC. Before you delete an Enterprise Edition or Enhanced Enterprise Edition IPv6 gateway, you must delete the egress-only rules of the IPv6 gateway. For more information, see Delete an egress-only rule.

  1. Log on to the IPv6 Gateway console.
  2. In the top navigation bar, select the region where the IPv6 gateway is deployed.
  3. On the IPv6 Gateway page, find the IPv6 gateway that you want to delete and click Delete in the Actions column.
  4. In the Delete IPv6 Gateway message, click OK.

Change the edition of an IPv6 gateway

When you use an IPv6 gateway to communicate with the Internet, you can change the edition of the IPv6 gateway based on your business requirements.

  1. Log on to the IPv6 Gateway console.
  2. In the top navigation bar, select the region where the IPv6 gateway is deployed.
  3. On the IPv6 Gateway page, find the IPv6 gateway that you want to modify and click Manage in the Actions column.
  4. Select a new edition, select Terms of Service, click Buy Now, and then complete the payment.
