        Since I started this thread I guess I should mention that I'm no longer having the problem.  The problem went away but I'm still running a stock 1.0.1 load.  Thinking more and more the root cause was my service provider…

          Everyone that is experiencing this problem, are you running miniupnpd on any interface? It seems to be that when I run upnp I experience this problem. Im running more test to confirm.

              Everyone having this problem, please try this from a shell:

              fetch -o /etc/ http://www.pfsense.com/~sullrich/devd.conf ; killall devd ; devd

                  We've established that dhclient is terminating prematurely for some reason. We're working hard to nail this down. Trouble is I'm the only developer experiencing this issue, but we are working on it.

                    Hi.

                    My connection failed again but the logs went away during my lunch.
                    Is not possible to fetch old logs ?

                    I deactivated the firewall interface and then activated again and everything works.

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

                          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.
