Configuring Access Control

Scenarios

DDM supports load balancing by default, but some regions may not support. If an application accesses DDM using a private IP address, there are no traffic restrictions. To control access, you need to configure access control for your DDM instance. The security group is still valid for access requests directly sent to DDM nodes.

Procedure

1. Log in to the DDM console.
2. On the Instances page, locate the instance that you want to configure access control for and click its name. The Basic Information page is displayed.
3. Toggle on Access Control.
   • If the instance has only one group, in the Network Information area, click on the right of button Access Control.

   • If the instance has multiple groups, the access control button is moved to the group information list. On the Basic Information page, in the group list, click in the Access Control column.

4. Click Configure. In the Configure Access Control dialog box, specify Access Policy, enter the required IP addresses, and click OK.
