Client isolation (whether wireless, by broadcast domain, IP filtering) is in conflict with ubiquitous device casting/streaming/detection features common in apps

Client isolation (whether wireless, by broadcast domain, IP filtering) is in conflict with ubiquitous device casting/streaming/detection features common in apps, which often do expect the ability to find each other on a LAN.
I think throwing those features out is a tough sell for the home consumer market, but makes sense in the SMB and above area.
- fidotron 2y agoThat's why you replace those features with things like a local mqtt broker. That way devices communicate only via the local services. I tried doing real time video first because it's widely assumed to be the hardest. Multicast is widely exploited for fingerprinting by smart TVs, unfortunately, much as I think mdns is a beautifully elegant idea.
- kbolino 2y agoI've never gotten local streaming to work, but that might just be down to the age of my "smart" TV though (which is now disconnected from the network due to lack of updates). But I have noticed that setting up a network printer is a lot easier than it used to be, and I assume that's because of LAN-based discovery, though I haven't dug that deeply into how it works.
