Plex flooding network on ports 32412 and 32414 from UNUSED NICs. (Synology NAS)

Can anyone tell me why plex broadcasts from link-local addresses associated with unconnected NICs?


My guess is this shows as “Any” for you, it’s under Settings > Network

Thanks for the reply and that’s a very good lead. I just dropped the 3 unusued interfaces via ssh to the Synology NAS plex runs on which fixed the issue. I will bring them back up and test your idea.

Thanks again.

Unfortunately, that doesn’t fix the issue. I enabled one of the interfaces I downed earlier and made sure I selected the only connected interface (eth0) for the preferred.
