I seem to having an issue with multicast/broadcast traffic on a VLAN (protocols like DLNA, Chromecast etc etc). I have a Mikrotik wireless AP in 'ap bridge' mode attached to RB850gx2 router trunk port (ether4 in this case). Some key characteristics I thought might be important for my issue (screenshots attached):
1. AP clients configured to use VLAN tag 20
2. The wAP itself gets a 'management IP' on a different network
All wireless clients connect just fine, receiving IP from DHCP server on VLAN2, and can ping/talk to each other. But the problem starts when I need to use multicast protocols like DLNA. I thought that by having clients on the same 'VLAN' that protocols that broadcast on that VLAN is visible to all clients. For me DLNA or Chromecast servers are not visible to other clients at all.
Am I missing anything obvious?
