      Today I did an experiment. uTorrent downloading/uploading for 7-8 hours - no problems in terms of service availability. Not a single pfsense service restart.

      As soon as I stopped everything and left the uTorrent in idle mode - pfsense started restarting the services every minute or so.

      Shortly - when the uTorrent is working - no problems, but as soon as it goes in idle - problem reoccurs.

      Any ideas why?

      Regards,
      Nick

          Hi Gertjan,

          Yes, I confirm there is uPNP activity on my Network (My Samsung TV is using UPNP, my Netgear access point is advertising UPNP etc.), however UPnP & NAT-PMP are disabled in pfsense. How is that affecting the drops? I've noticed, that uTorrent has several UPNP options active (please check the attachment) as well.

          Regards,
          Nick

            Hi fellows,

            I found some correlation between uTorrent settings and pfsense.

            When I disable the setting "Enable DHT Network" under Options/Preferences/BitTorrent in uTorrent, the problem goes away, but as soon as I enable it - WAN gateway restarts every 1-2 minutes.

            Any ideas how this setting is affecting pfsense?

            Regards,
            Nick

              This setting, as already said above, causes uT to establish hundreds/thousands of peer connections, regardless of whether you are transferring any files or not. See DHT Protocol.

                Thanks a lot. Hopefully the problem is solved now.

                It's pity, that uTorrent has this setting enabled by default.

                  Why is it a pity? It makes BitTorrent better. I have no issues with it. Have you tried plugging directly into your port to see if the problem persists without PFSense in the mix?

                    I run Utorrent on a seedbox and no issues with restarts.

                    I run 2.1.5 in front of the box. Hasnt upgraded to 2.2.2 yet.

                    Wonder if this could be related to the SYN ACK issue described elsewhere. When DDoS'ed the only thats in the logs, is a WAN restart within seconds of the box dyiung on me.

                      I'm using 2.2, no issues. One of these days I'll upgrade. But then 2.2.3 will come out right after, right?  ::)

                        I think 2.2.3 is not long now…

                          Hi guys,

                          I'm pleased to see that much activity :) Thank you!

                          Actually, when DHT is enabled and I'm actively seeding, there is no problem, but as soon as uTorrent goes in idle (all torrents stopped, but uTorrent application still running), all pfsense services restarts.

                          My WAN interface is configured in PPPoE mode and there is no modem in between - direct UTP cable to my ISPs neighborhood distribution point. My internet connection is 80 Mbit/s symmetrical line, quite pleased with it.

                          However I'll leave DHT disabled and continue monitoring my pfsense box.

                          @Supermule, can you please extend you thoughts on the SYN ACK issue and DDoS, because I would like to read some more info on the topic. Thanks.

                          Regards,
                          Nick

                            It's possible that the PPPoE server can't handle that many connections.
