PfSense randomly loses connection, and reboot is only solution.

rocketdog · Jan 30, 2014, 2:34 AM

So, I just did and fresh install on a new computer. Using the built-in NIC as LAN, and an USB-nic for WAN.
After a few hours I lost connection to Internet, but I still could reach the FW, and I all clients could ping the GW. All DNS:es were unreachable tho.
The only solution to solve the problem was to reboot.

Here are some info, just after the connection-loss:

I have no idea if the connection-loss started when ue0 seems to have went crazy.

Help would me much appreciated, since I finally upgraded the CPU from 450mhz to 2.53ghz, and 192mb ram > 2gb.

Thanks.

Did you already do the MBUF tweak? In /boot/loader.conf… you might try setting kern.ipc.nmbclusters="32768". The default I believe is 0. You'll need to reboot the firewall after the change.

This fixed some goofy NIC behavior in 2 of my remote office deployments.

mikeisfly · Jan 30, 2014, 10:00 AM

I had the same issue using a USB nic. The fix was to ditch the USB nic and do both lan and wan on the same port using vlans. Of course you will need a switch capable of vlans to make this work.

Do you just mean its using the axe driver or you have actually loaded some alternative kernel module? I'm not familiar with 'axe_4.ko'.

Thanks! I'll give this a try.

P.S. The FW hasn't dropped in 24 hours now!

Yeah, I just meant it's using the axe driver. I dunno why I wrote "axe_4.ko"

Google didnt gave me much, so I give it a shot here:
Another problem I've found is that I can't reach http://192.168.0.1 with Mozilla (with or without safemode), only through Chrome. With Mozilla it just keeps "reading 192.168.0.1", while in Chrome it's in matter of milliseconds.

And by the way, the comp I'm running the current FW on is an Dell SX280, I'm not sure if you guys can see it directly through dmesg, but I cannot get the thermal sensors to work. Any ideas?

stephenw10 · Feb 3, 2014, 11:14 AM

The thermal sensors dashboard widget (I assume that's what you mean?) relies on the sensor selection in System: Advanced: Miscellaneous:. Since the SX280 is pre-Core architecture it can only use ACPI to read the CPU temperature which relies on Dell having written a bios that passes that info to a non Windows OS.
If you just want to know what the CPU temp is you can probably use the mbmon FreeBSD package to read it but it doesn't talk to the dashboard widget.

Excatly. After a lot of testing, I've come to realize that neither the ACPI-thing nore mbmon works.

rocketdog · Feb 11, 2014, 2:32 AM

I'm not sure what wrong, but suddenly my FW starts to act like a monkey. It loses all connection to my gateway, and the only solution is, as topis say, reboot. 'dmesg' gives nothing. Anyone got a clue? This is really frustrating since I'm running TOR, http, mumble etc.

stephenw10 · Feb 11, 2014, 11:06 AM

So you can still access the webgui? And can you, like previously, still ping the gateway?

What is the gateway? Is the pfSense box behind another router or does it have a public IP on WAN? How is it connected?

You need to methodically go through and identify exactly which part of the connection is failing. What you can ping and what you can't. Is DNS working? Does the routing table look reasonable?

It's interesting that neither ACPI or mbmon work with that box. There must be a few people running identical hardware since they are so common. There will at least be people running FreeBSD on it. Do you have the most recent bios?

Steve

rocketdog · Feb 12, 2014, 5:21 PM

Yeah, I can access the webGui. The GW is down, cannot be pinged (red-flagged @ webGui) etc. DNS:es can't be reached..

I have a static ip, static GW, and the FW is connected directly to the "wall-jack".

Not sure about the BIOS, but could take a look..Been thinking about things getting overheated, but then why would just the GW drop?
The box seems no the have any support for temp-support, so I have no idea about if it is a overheat-problem..

stephenw10 · Feb 13, 2014, 2:15 PM

Ok so the gateway device is some box at your ISP?
When the gateway is marked down there will be something in the system logs. Often it will report the reason for marking it down as either excessive packet loss or delay. If it does not it usually means the connection has gone down. Is the WAN interface still showing as UP?
It may be the remote box doesn't like being pinged continuously. You could try altering the ping interval (1s be default) or disabling apinger entirely in System: Routing: Gateways: (edit gateway - advanced section for apinger tuning).

@rocketdog:

If you do a Dmesg after the GW drops, does it show the link flapping on the ue0 nic?

If so, you either have a failing NIC or just general instability with the USB NIC (these aren't exactly what I would consider to be stable).

If the System Logs do not show Apinger alarm, restarting the NIC and followed by a filter reload, then the problem probably lies with the NIC (I've had this with a failing NIC before).

Yeah, tons of ups and downs. The FW has worked as a charm for the last few days…I tuned some stuff on a server (did some ifconfig eth0 RX downtune IIRC), and the TOR-server went down about 20%...Before, and when the FW-problems occured, the tor-relay was full throttle.. So I guess it's just this damn USB NIC. Too much traffic and it goes bananas..

How do you reload filters?

Looking at dmesg, I've lost connections several times…probably while I've not been using internet etc. And I have no idea for how long the ue0 is down, and why it comes back up again. Ideas?

Found this! What could cause this? 1-5 minutes downtime, but no "uplink" messages?

Edit: Missed to get these lines in the screenshot.

"Starting Alarm Pinger", then 10 seconds later I'm offline. Where can I find options about this thingy?

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.
