Network config with ESPhome devices

Hi

I am not quite sure where to address this…

I plan to put my ESPhome/IoT devices in vlan 245 in my setup … My HA is in vlan 225.
I have an Ubiquiti EdgeRouter in between - but how show I handle the mDNS stuff ?

IGMP proxy or mDNS repeater in the EdgeOS config ? And any suggestions on how to configure it?
