I haven't tried, but I it's detectable. Plex only sends out a handful of packets every 5-10 seconds. It wouldn't really matter except that the interface I want it to leave alone is attached to an internal network I use to develop/test IoT and industrial Ethernet devices, and I want to be able to run tests that are as predictable and repeatable as possible. It would probably be better to run Plex on a separate, small, silent, low-power, headless server but I've already got enough machines to maintain. -- Grant
