Background As a follow on from a previous post I discussed how to enable the IGMP Proxy in the USG product line to permit cross VLAN mDNS traffic. In the UDM/UDM-Pro line its a bit different. There is config.gateway.json file anymore. There are multiple workarounds out there to run Docker contaienrs to add in extra functionality, however this is not one of them.
If you are looking to bypass your AT&T gateway then you will need to head down the Docker path, but if you are looking for just Airplay across VLAN’s you have arrived at the correct article.
Background As a follow on from a previous post I discussed how I locked down VLAN’s from a IoT VLAN to my core data VLAN. In that post I described how I got my Sonos speakers and Sonos controller to work over locked down VLAN’s. I recently hooked up an old Apple Airport Express and music wouldn’t flow when I was on the data VLAN to the IoT VLAN where the Airport Express resided.
Background At home I run the 4 port USG router on my Unifi’ed network. I have a couple different VLAN’s, Data, Management, Security, IoT, and Guest. Each of these networks already has some policies that prevent some of the VLAN’s talking to each other. For example I have some firewall rules that prevent my security cameras from talking to the IoT network and talking out to the public Internet. For the past couple months I haven’t been running a locked down IoT network.
