Many of my devices want to use mDNS (multicast DNS), the one that is at the base of many protocol/products like:  apple bonjour, avahi, zeroconf, ....

They are not able to do it on my Deco M5 managed network (router mode).

As far as I know it the protocol needs a router configured to enable multicast, specifically IGMP V2, but I cannot find a similar option in (extremely poor) Deco M5 app settings.

Anyone has mDNS working in his Deco M5 based local network?

NOTE: Not sure about my hardware version, I red "EU/1.0" on a barcode sticker so I entered "V1".
