The Client Isolation feature on RUCKUS access points and controllers prevents wireless clients connected to the same SSID from communicating directly with each other within the same subnet. This is particularly important for guest or public networks to enhance security and privacy. However, administrators may sometimes need to allow access to specific network services or devices-such as printers, gateways, or media servers-within that same subnet.
RUCKUS systems address this need through the Isolation Whitelist capability. As described in the RUCKUS One Online Help and RUCKUS Cloud documentation, the Isolation Whitelist allows administrators to specify destination IP or MAC addresses that are exempt from client isolation rules. This enables controlled access without fully disabling client isolation across the network.
Other options like directed multicast or access control list (ACL) manage traffic types or filtering policies but are not specific to client-to-client communication exceptions. Therefore, the Isolation Whitelist is the correct answer.
