I am having an issue configuring mDNS between 2 VLANs in my Omada setup.

Controller

Controller Version 5.12.9

Model OC200 1.0

Firmware Version 1.26.3 Build 20230906 Rel.36269

Router:

Version 1.3.1

Model ER605 v1

Firmware version 1.3.1 Build 20231207 Rel.61384

I have a main management VLAN ( ID 1) and an IoT VLAN (ID 2).

My Homepod sits on the main network along with all the clients (iPhones, Mac etc) and on the IoT VLAN I have a garage door switch, and a few cameras.

I do not have any ACLs blocking traffic between the VLANs, I can ping 192.168.2.x from 192.168.0.x

While connected to my management network with the Discover-SD app I see a bunch of mDNS services (Homekit, printing etc) and when connected to my IoT network I see  Homekit and a custom _ewelink protocol (my garrage door). 

I would expect with the rule above to see the _ewelink mDNS advertisments flow through but they do not.

Are there other settings that I need to do ?
