Building out an IoT VLAN with an OpenWRT RPi functioning as a VLAN bridge (via a single Ethernet port).

Getting mDNS proxying working was a PITA. Everything you can Google is out of date, so
you have to poke round a bit. Firewall rules take some getting right too, especially if the bridge isn’t also your internet gateway (it’s not).

Still, it’s working, and I’m quite pleased. Can’t AirPlay across it yet, but that’s a project for later.
