PfSense randomly loses connection, and reboot is only solution.

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.Steve

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,
