Due to the lack of clarity (to me anyway): When you say Chromecast you mean actual Chromecasts from Google and not just devices using the 'Google Cast' protocol (there is a couple of reasons.) I'm assuming that the Chromecasts are connecting via Wi-Fi (rather than the optional Ethernet connection) The Chromecast and Guest are on different SSIDs. The SSIDs are in bridge mode and are on different VLANs As has been pointed out Bonjour forwarding is of no benefit to a chrome cast, Bonjour is essentially Apple only.   Not every manufacturer seems to implement the protocols properly properly both TiVo and Samsung devices behave quite differently to an actual Chromecast.   If you really need to use something along the lines of Avahi to permit the protocol to traverse VLANs. Chromecasts also use an ultrasonic signal to advertise their existence and to permit guests to connect was this previously used? Has there been any recent Chromecast firmware updates?   ...
