            Hi again.

            There is another log but the symptom seems the same: the interface vr0 that is connected to a router goes down then it can't goe up again:

              Is that interface marked for DHCP?  It thinks that it is not.

                No, it's not.

                No dhcp in vr0.
                The dhcp on router is deactivated too.

                Thanks in advance.

                    The vr0 is the network interface of the firewall of our second link to workstations. It is connected to a router.

                      This makes the situation even more puzzling.  Why would it think that you are unplugging or plugging in vr0?!

                        Check your gmail account freax … I am working on this issue now and need your help.  I cannot guarantee when I'll have time or interest to work on it again so right now is your chance to get it solved!

                          Please test the latest snapshot if you are still having problems and post the logs.  I have added some debugging information.

                              Hi again.

                              I'm at 180 km from the firewall so I will test it monday.

                              Thanks.

                                I've been experiencing this problem lately and it still has not been resolved for myself either.

                                ISP: ZoomInternet

                                I'm not sure my exact snapshot, but it was most recently updated on Jan29.

                                Any info that I can provide to help get this resolved I am more than willing to give.

                                  Please update to a recent snapshot like I asked everyone else to do.

                                    Anyone have an update?  Or is the problem finally fixed with recent snapshots?

                                      do you mean snapshot 02-02 ?? if you do, the problem is not fixed =(
                                      still ending up with "short write: wanted 21 got 0 bytes"

                                        Yes, the updated snapshot as of a day or so.

                                        Please provide the entire log file.. As much detail as possible.  You can X out IP addresses but I need to see the chain of events from before and after this happens.

                                        Also, for the record, who uses PPPOE and who has just a regular DHCP WAN?

                                          I've updated but still now it didn't stop. Maybe I can turn off then on the router.

                                          I have 2 links:

                                          • fxp0 that is our pppoe wan that is used for servers and DMZ;
                                          • vr0 which is in opt1 that serves our worksations; This is connected to a router trought a diffrent ip.

                                          I think I had 2 different problems:

                                          • pppoe (fxp0) went down from time to time and I think it was solved with some latest update. This was the worst because sometimes we dind't have vpn at weekends. I think it's solved.
                                          • now I still have the last problem which the workstations don't have internet with some dhcp problem. There isn't dhcp activated neither on router or firewall.

                                            I have made some more changes for debugging.  Please test todays snapshot.

                                            Thanks!
