TUMS Posted September 23, 2016 Share Posted September 23, 2016 First of all everything is behind a NAT router running shibby tomato. No ports are open including, uPnP/NAT PNP all turned off. All unraid user shares are locked down to read only. I'm running binhex delugeVPN docker (PIA VPN) downloading a torrent and i'm starting to see these messages i've never seen before in my main unraid log.

It's got to be something to do with the torrent i'm downloading. My guess is that it's harmless but I just want to check. Quote Link to comment
