I am considering upgrading our 5508 WLCs to version 7.4.1 to take advantage of the Bonjour gateway. What I want to do is allow clients on our guest wireless network to access things like the Apple TV in our conference rooms. My intention would be to have the Apple TVs on a separate vlan. Obviously, the Bonjour gateway would allow for access between these 2 networks. The question I have is this. If I have client isolation turned on my guest wireless network, is it still possible for these devices to access Apple TVs on another network?
