      Everyone please update to the latest snapshot and see if that solves your disconnects.

      http://snapshots.pfsense.com/FreeBSD6/RELENG_1/updates/

      What has changed that would fix it?

        Bill's patch. I'm running 2-14 and I haven't had an issue yet. Wondering if anyone else will with the new snapshot.

            Do you see anything in the filter logs showing blocked packets around this time?

            Also, anyone having this problem, please run this from a shell:

            fetch -o /etc/inc http://www.pfsense.com/~sullrich/filter.inc

              no, i have not seen any blocked packets that could have something to do with this, but i am one of those
              who are affected by the "promiscuous mode disabled", and therefore my firwall logs stops after a while.

              isn´t there a way to catch the dhclient message and "restart" dhclient when its terminating, just as a workaround until you pinned down the problem ?

                We already have code to detect this but it doesnt appear to be working.

                  Good news!

                  I was able to replicate this problem thanks to sdale and Vescovo.

                  Vescovo had the final fix and it has been commited.  Please upgrade to a snapshot about an hour from this message.

                    I think you forgot to wave your magic voodoo wand, problem still exists  ;). I think the problem lies in the rc.newwanip not catching the interface being assigned 0.0.0.0 IP address.

                      i did a workaround for that problem a couple of months ago:

                      rc.newwanip:
                      –---------------------------
                      if($curwanip == "0.0.0.0") {
                              log_error("Failed to update WAN IP, restarting dhclient.");
                              exec("dhclient {$interface_real}");
                              /* die now, dhclient will kick off rc.newwanip again? */
                              exit;
                      }

                        Is not the real deal but if you disconnect the cable and connect it again you won't have link.
                        I have both ends with fixed ip (the router and firewall interface) and it should have link again like it should.

                        Like I said, i think it's a good way to debug whenever you want. Tests always available.

                        Sorry if i'm wrong.

                            I have added a workaround and verified that it does indeed seem to work.

                            Update to the latest snapshot at least an hour from now.  Currently 11:46PM EST.

                                I really don't see how it could not work.

                                Run this from a shell:

                                cat /sbin/dhclient | grep reload

                                What does the results say?

                                  Enter an option: 8

                                  cat /sbin/dhclient | grep reload

                                    Can someone else please test?  This absolutely works for me after 20 hours when normally it would break in 30 minutes…

                                      Works fine for me, only lost my ip 2 times, and that was before the latest snapshot.

                                          Works fine for me, only lost my ip 2 times, and that was before the latest snapshot.

                                            Atm there is a workaround in pllace that will restart the dhclient when it exits. Does it get restarted?
