      @tastyratz:

      what could be done locally to cripple wan but not lan?

      Change the default route information or gateway. Then you have access only to local subnet services. That would include the DNS forwarder in pfSense. Of course I have no idea why it might be doing that. Rogue DHCP server on your network? That happens surprisingly frequently and can cause all manner of problems.

      I suggest you run an 'ipconfig /all' on your Windows box before and after failure and compare the two.

      @tastyratz:

      That being said: I have vmware workstation loaded on my desktop. I just fired up one of the virtual machines and attempted to pull up a web page - same end result for what it's worth.

      Is this the same machine you run utorrent on? You mean a VM running on that machine after it fails to connect also fails to connect?

        ipconfig nets the same IP. if I do a release/renew it does get an IP (same one) from pfsense and gateway is the same. It behaves the same both before and after restarting the pc.

        Correct, once my desktop no longer communicates with the internet, the vmware machine running on the same desktop pc also has no internet access.

          Is the VM getting a new IP from pfSense or is it NATed from the host machine?

          What about the routing information, try 'route print' before and after failure.

            VM actually grabs via pfsense, it shows up in the arp table there.

            Here's a fresh route print before failure (192.168.1.1 is the pfsense machine, and 1.11 is my desktop):

              Hmmmm.  :-\

              What do you have between the pfSense box and the client? Assuming you have some switch does it have any features that may be contributing to this? Have you tried power cycling the switch? Have you tried removing the ethernet cable from the client?

              Otherwise I'm stumped!

                yea this is a real tough one. It's just a standard trendnet gig dumb switch, nothing to it… no features. I haven't bounced it yet or messed with the cable because of that. Nothing else in the middle

                  To update anyone with similar issues, dropped to uTorrent 2.2.1 Build 25302 (but kept settings) issue persisted.
                  Tried installing Vuze and seeing if it works. I had the same thing happen on vuze, guess it wasn't utorrent kicking it off just torrents in general.

                  I since rolled back to 2.0.0.4 and also tweaked my network adapters settings. I disabled both vmware network adapters, then went to config my main adapter - disabled vmware bridge protocol and "AppEx Networks Accelerator". I think the AppEx piece was my problem, looks like it stems from something called "AMD Quick Stream Technology" - an AMD QOS shaper that must have come with my motherboard driver pack.

                  Since then I have downloaded 1 Terabyte and not had a single crash while before I couldn't break 20gb at times. I hope this helps someone else ripping their hair out.

                  Mystery solved, thanks everyone for their time and help.

                      I have the exact same problem that is causing me a lot of grief the problem is when the net goes down (my entire network) my vpn crashes too and NOTHING internet related works even when I shut off utorrent the net remains down untill I reboot the pfsense AND reset the modem.  If I don't do this my net remains down.

                      I just installed the latest version of vuze and I'm trying it now but seeing as this is a problem for you too I may try and revert to to utorrent 2.0.0.4 if vuze causes the issue too.

                      Thanks I will keep you posted on my findings.

                      I do have

                      HVAP
                      Squid
                      Squid Guard
                      and PF blocker running I downgraded to

                      PFsense assuming the newest version was causing the problem, even with the older version I have this issue.

                      2.0.1-RELEASE (i386)

                        vuze just crashed too, now I installed utorrent utorrent 2.0 build 17920

                        I'll run it after lunch, it usually crashes within 20 min

                        I'll report back.

                          @nambi - What is in the pfSense system logs prior to the network going down?

                          I assume you pfSense box is hitting a limit somewhere–CPU, RAM, etc.--and that's causing the box to lock up.

                            my pfsense just crashed again here using an old version of Utorrent.

                            This is what I notice, when the net crashes I http into the pfsense box, the GUi comes up very slow with 1/2 of it, not showing eventually the screen shows the full UI.

                            In the logs I see errors upon connecting to the IPSEC and other services that require the internet.

                            The memory is at 14% (4gm ram)
                            the cpu (intel atom d525) is at 4%

                            the only thing I see in the logs is.

                            Apr 22 15:50:02 syslogd: kernel boot file is /boot/kernel/kernel

                            Apr 22 15:47:05 php: /index.php: XMLRPC communication error: RPC server did not send response before timeout.

                            Unfortunately this info doesn't provide me with much unless I'm looking in the wrong area.

                              This is clearly a completely different problem to tastyratz issue. It's effecting your whole network not just one machine as the title suggests. Since he solved his issue I guess he won't mind his thread being hi-jacked.  ;)

                              Since you are using torrents I would first guess that you have hit a limit in the number of connections allowed. With 4GB in your pfSense box it shouldn't be a problem. How is your modem configured? Is it in bridge mode?

                              Look at your MBUF and states usage in the dashboard before you start the torrents and monitor it as the torrents pick up.

                                Thanks Steve I'll start a new thread so I don' t hijack this one.

                                I'll try your suggestion tomorrow when I have others off the system

                                Can you tell me what

                                "MBUF" is?  Another really weird characteristic is, my local server which services files for our DB is inaccessible when this happens.

                                CPU usage is below.  My UPNP is disabled should it be enabled?

                                  See: http://doc.pfsense.org/index.php/What_are_mbufs%3F

                                  UPNP should only be enabled if you know you need to have it.

                                  Your system output shows that PHP is struggling with something though that could be a symptom not a cause. That would tie in with the webgui being unresponsive.
