(Chrome)casting Across VLANs

Hi all, I've run into an interesting problem, and I'm curious if anyone has had a similar experience. I have 2 VLANs on my network, one for my main devices and one for my IoT devices. I have a couple Google Homes and a Chromecast with Google TV, which I would like to be able to cast to. When I first open up the casting page on my device, it cannot find them, but if I connect my device first to the IoT VLAN, discover the devices on a "Cast To" page on my phone or laptop, then return to my primary net I can then cast to them as expected. I assume maybe there is some IP or MAC caching going on here but I truly have no idea what the cause of this is.

My firewall exceptions look like this, which might even be overly permissive for what I need.

Thanks in advance!

Okay it turns out my solution was to I simply follow this guide, in addition to my existing steps.

Basically, install avahi-daemon, enable reflector, then make a rule allowing your zones to send traffic from and to 5353 to

Neat, been wanting to isolate my Chromecast devices as well. Will look into that as well, thanks.

Happy to help! I don’t think there’s a need for ports 1900 or 9000, if you decide to set this up yourself. But let me know what you find!
