      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

                      Binary file (standard input) matches

                          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?

                                    It can take up to 5 minutes to restart dhclient depending on if check_reload_status is running.

                                    So if you still have trouble please check that check_reload_status is running from a shell by doing:

                                    ps awux | grep check_reload_status

                                    Also, cat /etc/crontab | grep check

                                      I found yet another problem.  This WAN DHCP issue has been nothing but fun!

                                      Try out a recent snapshot atleast an hour from now.

                                          Yes the problem still exists and we have been racking our brains out – literally.
