WiFi setup (lemmy.omat.nl)

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?

This is what Layer 3 is for. You need to open the relevant port between vlans (e.g. TCP 443 for https) on the firewall. I think its UDP 1900 but may vary by appliance.

I'd also allow multicast, ICMP (ping) and DNS between your vlans as a minimum depending on what they're used for.
