Hi,
I sometimes hear/read people putting their tv and other devices on a guest Wifi or even on a separate VLAN. Most guest WiFi’s also have client isolation. I can understand that desire but I’m always wondering how that works in real life.
If you have a TV on a guest Wifi, how can you still cast things to it, as I assume your phone is on a different Wifi.
If you put your heating a different VLAN, how can you control the heating from your server that’s on a different VLAN?
What’s your setup in this regard. Is it worth to split? And what do you split and what not?
Doing these “find your device with magic and do stuff” things can be a bit troublesome across networks. Some is possible to set up but sometimes it just doesn’t work. It is the tradeoff between security and comfort.
A 1:1 NAT to the other network usually solves it for me.
What about mDNS?
