Multi-Cast Issue.

I have 4 devices doing routing and Switching.

Action technology vt1000 (ISP)

Port 1 of the VT1000 goes to an ASUS RT-66AC on the Wan port.

Port 2 of the VT1000 to their IPTV box

Port 3 of the VT1000 to their IPTV box

Port 4 unused

The Asus 66U port 1 goes to a Dink Gigabit Non managed 24 port switch.

Port 2 goes to a second Asus 66U which is set in AP Mode

I have the action tech set to do transparent bridging due to the IPTV boxes mist have Multicasting on.

I have a Multi-room Sound...
