    PfSense randomly loses connection, and reboot is only solution.

      How far apart are these up down events?
      Why is it using promiscuous mode? Is it bridged?

        Promiscuous mode? I have no idea. I've never seen options like that. It is no bridged.

          Usually a NIC would only need to use promiscuous mode if it has to be able to process frames addressed to other MACs.  This is the case if it is part of a bridge or has been used for packet capturing among others.

            According to "Diagnostics > Packet Capture" promiscuous mode is disabled. By the way did, did you see my edit on my previous post?

              You can tune apinger or disable it completely in System: Routing: Gateways: edit gateway, advanced.
              That's not going to help if your usb nic really is flaky though.

                So I guess it's just this damn USB NIC. Too much traffic and it goes bananas..

                How do you reload filters?

                Seems like the case.  USB NICs aren't exactly stellar performers.  I seriously recommend getting a cheap VLAN capable switch (Netgear GS108T or HP Procurve 1810-8G or Mikrotik RB260GS) and using that with your BGE nic to create the WAN & LAN interfaces via VLANs instead.  It's far more stable than trying to work with the USB NIC.

                  As soon as I turn on squid, the USB drops within hours. Since I disabled it, it hasnt dropped once.  :) Too bad tho, since I really liked Squid. I guess I'll start using it the day I find relaying onion traffic boring.  8)

                    Sorry for keeping this thread alive, but..since I figured out, the reason the USB-NIC overloads is because of Squid, is there any certain tweaks I could do to Squid towards the hardware?

                      What is squid doing when the USB nic drops? Line up the logs. Look to make the logs more verbose.

                      Have you tried a different set of USB headers? Does it correspond with high load on the PC?

                        After all, it's just not Squid, it is traffic itself. USB-NIC/GW still drops, just not as frequent as with Squid enabled.

                        Attached some RRD graphs. If you want RRD graphs of CPU or other system-related stuff, just give me a shout.

                          Hi there,

                          We used to use USB NICs and can confirm this flapping behavior - UP/DOWN within seconds. The only solution is NOT to use USB NICs with pfSense/FreeBSD. Go for VLAN switches and non-USB NICs.

                          Thanks,
                          msu
