        Sorry to say, but I have tested another firewall and all my problems disappeared.
        The thing about my ISP is changing my IP a lot.. Yea, it disappeared. Clearly it was pfsense. On the new firewall I have had the same WAN IP since the installation ~2 days ago.

        The weird part about this is that pfsense has been working before without problem. All problems started when I changed my ISP. So.. again, not expert, but I believe ISP have different ways to give IP's and pfsense can't handle them all in a correct manner.
        On the new firewall I can see in the logs that it comes false dhcp offers from time to time on the WAN. The new firewall just drops this. Maybe pfsense doesn't? Anyway, I have no clue…

          it looks like it could work, BUT ! i got this:

          Dec 17 15:25:11 dhclient[11983]: exiting.
          Dec 17 15:25:11 dhclient[11983]: exiting.
          Dec 17 15:25:11 dhclient[11983]: connection closed

          Dec 17 15:25:11 dhclient[11982]: wan: not found
          Dec 17 15:25:11 dhclient[11982]: wan: not found
          Dec 17 15:25:11 php: : Failed to update WAN IP, restarting dhclient.
          Dec 17 15:25:11 php: : Informational: rc.newwanip is starting.

          it seems like the script is using "wan" as a real interface name.
          maybe it should be like this ? :
          exec("dhclient {$argument}");

            I don't know if this new script fixes the Loose IP Problem. But after replacing the old version with the new one I had problems with my OpenVPN. Always the script tried to re synced the OpenVPN, I received a error:

            Port [undef] 1194 already bound

            I use the pfSense-1.0.1-Embedded.img.gz with just changing the /etc/rc.newwanip to the proposed version.

              Nextrem: not related, known issue, please see the openvpn threads.

              Everyone else:

              I have updated rc.newwanip, try this version:

              http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/etc/rc.newwanip?rev=1.21.2.24;content-type=text%2Fplain;only_with_tag=RELENG_1

                  however, i dont think this script will solve the "short write: wanted 21 but got 0 bytes" error, or does it ?

                    It does not solve it, it simply works around the issue for the time being.  Anyone else tested?

                      i know, but i think there is two errors,
                      first, when it failes to update the wan ip, that have been "solved" with the script.
                      but the second with "short write" will not be solved by this, i think.

                            Sorry for no better news.

                              As this problem gives biggest headaches to me, I've decided to use my linux server to run this via cronjob every minute:

                              wget -q –no-check-certificate --user=XXX --password=XXX --post-data "interface=wan&submit=Renew" http://IPOFPFSENSEGUI/status_interfaces.php -O /dev/null

                              This works fine for now. Hopefully the real solution to repair the dhclient will soon be there…

                                Then use a 30$ router!  I am interested in constructive feedback, not Mr. Obvious taglines!

                                  My apologies. I'm sticking with PFSense. You're doing great work.

                                    Unfortunately we are using the same dhclient that we used prior to 1.0.  So nothing has changed in this regard.

                                    But I do have an idea.  Give me some moments, I would like to test ISC-DHCLIENT again and see how much work it's going to be to dump the OpenBSD dhclient that FreeBSD imported.

                                      Thx alot. Due to the workaround I've got plenty of time now. Please let me know when there's something I can contribute / test in order to help.
                                      I'll watch this thread anyway.

                                      Cheers

                                        From a shell, issue this command (full installations only!):

                                        fetch -q -o - http://www.pfsense.com/~sullrich/tools/cvs_sync.sh | sh

                                        Sit back and let it do it's thing.

                                        After it is done, issue shutdown -r now or reboot from the webConfigurator or option #5.

                                          Hi sullrich

                                          I've just issued:

                                            You can cancel your upgrade for now. We found some remaining issues with the new dhclient (some things still have to be changed due to different syntax). It's working on reboot though. We'll test some more things later and post when we have a new version to try.
