Whitelist

You can add a whitelist to specify the IP addresses that can access the listener.

  • Only enhanced load balancers provide this function. Adding the whitelist may cause service risks. Once the whitelist is set, only the IP addresses specified in the whitelist can access the listener.
  • If access control is enabled but no whitelist is added, the listener cannot be accessed.

  3. Under Network, click Elastic Load Balancing.
  1. Locate the target load balancer and click its name.
