I am experiencing an issue with multicast traffic pass-through when connected wirelessly to my Ruckus system. The software I am using is RadioRa2 and we use this software to identify the Main Repeater on the network. The software sends out a multicast message to search for the MR. When I'm hard wired into the network it finds it every time. But if I'm connected wirelessly it will not even find it.
Ruckus has a directed-multicast feature that will by default, convert the first 5 multicast (UDP) clients into Unicast (TCP) for better delivery. This is usually optimal for many applications, but not all. In your case, you probably want to let all multicast join/updates to flow unchanged.
KBA-4568 might be the most helpful to determine which WLAN you're using these clients on, and how to disable directed-multicast and either enable or disable IGMP snooping (try disabled first, meaning let the pkts go clear to the client, don't have AP answer on their behalf). https://support.ruckuswireless.com/answers/000004568
