Zyxel USG 110 and mDNS?

Venturing into segmenting the network with multiple VLANs (Guests, IoT things, Admin etc.), I seem to have multicast in place (USG 110 as router, GS1920-48 switch and Ubiquity Wi-Fi), but struggle with mDNS for e.g. Chromecast & other mDNS services.
I am unable to find good information on this for the Zyxel router, so I'm wondering if it needs to do other than the VLAN routing, while the switch manages the multicasting? Where should mDNS be handled?

  • I'm having the exact same issue using a GS1920-48 with a Unifi USG and multiple Unifi APs

    I think that you can/need to do something specific on the UniFi USG. It just can't match the Zyxel USG110 for me, so I'm really keen on keeping the router. My multicast works across my VLAN's, but mDNS doesn't :(


    But make sure your multicasting works first :)

    Hi @mrwee

    Currently, the USG110 doesn’t support multicast across different VLANs.We will put it into the idea category for future development evaluation.

    Ok, thanks for your reply. This is, needless to say, sad news. Will see what options we have then. Hopefully this will be implemented in the USG range soon :)

    This is exactly the same problem as I have mentioned in my idea https://community.zyxel.com/en/discussion/5444/atp-200-multicast-and-broadcast-routing-across-vlans-to-enable-media-sharing-protocols#latest. So we can join our forces for this feature request :-).

    Hi @mocr. Interesting possible workaround. I'm also still struggling getting a viable solution up and running for multicast + mDNS. It seems like more and more products are utilizing multicast, so one should think there were more solutions out there.

    Did you test the bonjour-reflector?
    When I search for info, it seems like USG can support multicast across VLANs, if the correct rules are in place. I just can't get it to work.

    Hi @mrwee,
    I have also tried setting up rules but was not successful.

    I do not know how to test reflector without putting additional HW into the NW. I believe that we are not able to solve this without such feature implemented on the ATM / USG.
