Hello, My problem is that the Spotify connect features with sonos use mDNS with multicast 224.0.0.251 to discover device. I have multicast rules forChromecast already, it's working successfully and it use also the same address, so I'm wondering why it's not working with spotify. When looking in wireshark the "drop", I see the packet outgoing but never come, It looks like the firewall is not sending it to the correct VLANs, so why with chromecast it's working ? Another weird things, when initializing the spotify connect to a device in the same vlan as sonos, the sonos is appearing in the spotify application in both the one in the VLAN and the one in the other VLAN. I have this error when trying to use as mcast group 224.0.0.251: https://live.paloaltonetworks.com/t5/Management-Articles/Multicast-Configuration-Failing/tac-p/206160#M5290
