Enabling or Disabling Private Network Access for a Load Balancer

Scenarios

GeminiDB Redis allows you to enable or disable private network access for a load balancer.

Precautions

• A load balancer address does not support security groups. After instance creation is complete, configure IP address access control. If no whitelist is configured, all IP addresses that can communicate with the VPC can access the instance.

Enabling a Blacklist/Whitelist for a Load Balancer IP Address

1. Log in to the GeminiDB console.
2. In the service list, choose Databases > GeminiDB Redis API.
3. On the Instances page, click the target instance.
4. In the Connection Information area, click next to Access Control.

5. Select Blacklist or Whitelist and specify IP addresses in that list.

   • Blacklist: The blocklist and allowlist cannot be configured at the same time. If you switch between lists, your previously entered settings will be lost. IP addresses in the blacklist cannot be accessed. Exercise caution when performing this operation.
   • Whitelist: The blocklist and allowlist cannot be configured at the same time. If you switch between lists, your previously entered settings will be lost. Only IP addresses in the whitelist are allowed to access the system. Exercise caution when performing this operation.
