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).

Create an 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, click Create IPv6 Gateway.
  4. In the Create IPv6 Gateway dialog box, set the following parameters and click OK.
    Parameter Description
    VPC 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 that is associated with the IPv6 gateway.
    IPv6 CIDR Block Type Specify whether to assign an IPv6 CIDR block to the VPC. In this example, Assign (Default) is selected.
    Note This parameter takes effect only when the IPv6 CIDR block is disabled for the VPC to which the selected IPv6 gateway belongs.
    Name Enter a name for the IPv6 gateway.
    Enable IPv6 CIDR Block of all VSwitches in VPC Specify whether to select Enable IPv6 CIDR Block of all VSwitches in VPC.

    If you do not select this option, you can go to the vSwitch page to enable IPv6.

    Note This parameter takes effect only when the IPv6 CIDR block is disabled for the VPC to which the selected IPv6 gateway belongs.

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 or the description of the IPv6 gateway.

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 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.
