Avahi mDNS reflector in one direction

I have a setup split into 3 VLAN networks (iot, home, corporate) with Avahi reflector covering all 3 interfaces. I would like to limit avahi so it only reflects in one direction between specific networks, for example:

Devices in iot should see devices in both home and corporate.
Devices in home should see ONLY other devices in home and iot
Devices in corporate should see ONLY other devices in corporate and iot
Devices in home should NOT see devices in corporate and vice versa

I have tried different combinations of firewall rules but can't stop home devices seeing corporate devices and vice versa. I have the issue where home devices are reflected into IOT (as desired) but these are then subsequently reflected into corporate (not desired). Similarly, corporate devices are reflected into IOT (as desired) but these are then subsequently reflected into home (not desired). Any help is much appreciated.
