It appears that when using client isolation, the client isolation MAC permit list will only allow wireless client devices to contact a permitted MAC address (such as a wireless printer) if the MAC address is connected to the wired LAN network or connected to the same WLAN network, but on a different AP. If the permitted MAC address is connected to the same WLAN as the client device on the same AP, the client device is unable to connect to it.
Please implement a feature that allows device MAC addresses on the client isolation MAC permit list to be contactable by moblie clients on the same WLAN, connected to the same AP.
