Hi
I have now got a seperate VLAN for my IoT devices, they are running as expected on this LAN and can call home etc
I have blocked everything on this network to/from my LAN so to be sure the network is truely isolated
What i want to do is, some of the services allow you to connect to them if you are on the same network, for example my air conditioner will allow me to use the app and connect directly through my WLAN saves routing out via the net and back in
I have narrowed it down to a list of services i need to somehow broadcast so that the apps can pick them up
my devices are
Logitech Harmony Hub
if i put this on same network as my phone/tablet, it picks it up in local mode, moving it back to seperate network onyl allows me to connect via external only
Samsung Smart Air Conditioner< ------ appears to broadcast using ssdp, UDP
Phone checks for an AC on the WLAN using HTTP UDP 1900, AC responds https 1900 and allows app to work in "at home" mode
Alarm System -
Just requires port 443 for web UI access <------ this one is easy, ill just create a lan -> iot rule to allow HTTPS.
Is it just a matter of allowing required ports, or is there a broadcast type required
thanks in advance.
