Access Control Lists (or ACL’s) are lists of Mac Addresses from network devices which can be used to allow or deny access to SSIDs, Firewall, and Captive Portal profiles within the group.
The option can be found in the menu following group settings > network settings > access control lists and is available to groups that contain Balance, MAX, and AP One devices.
To create a new ACL select Add Access Control List, name the ACL, add the MAC addresses for client devices and save the List.
