    I running 1.0.1 and keep loosing my external IP.  Looking at the system logs I see the last entry for dhclient as:

    Nov 1 21:41:19 dhclient[5862]: bound to 71.12.165.131 – renewal in 42454 seconds.

    It is now Nov 2 12:39:27 and the log shows no other dhclient entries.  If I am reading the above entry correctly shouldn't I have had some time about Nov 2 09:41:00 that show a renew being done?

    Thanks for any info,

    John Morey

      Same problem here, running PFsense 1.0.1 on a WRAP Box.
      The WAN DHCP is always down after the ISP changes my IP.
      After i release the WAN IP manually everything is okay again.
      Is there a bug in the dhcpclient ?

        I did some more looking.  I checked /etc/db/dhclient.leases.xl0 and it contains the following entry:

        lease {
          interface "xl0";
          fixed-address xx.xx.xxx.xxx;
          option subnet-mask 255.255.248.0;
          option time-offset -21600;
          option routers 71.12.160.1;
          option domain-name-servers 24.197.160.17,24.197.160.18;
          option broadcast-address 255.255.255.255;
          option dhcp-lease-time 84908;
          option dhcp-message-type 5;
          option dhcp-server-identifier 172.26.96.132;
          option dhcp-renewal-time 42454;
          option dhcp-rebinding-time 74294;
          renew 4 2006/11/2 14:28:52;
          rebind 4 2006/11/2 23:19:32;
          expire 5 2006/11/3 02:16:26;
        }

        It states that the renew time should be 2006/11/2 14:28:52.  As of now my latest log entries are:

        Nov 2 14:50:13 sshd[58433]: Accepted keyboard-interactive/pam for root from 192.168.63.17 port 37491 ssh2
          Nov 2 14:16:17 dnsmasq[5943]: reading /var/dhcpd/var/db/dhcpd.leases
          Nov 2 13:25:10 sshlockout[53783]: sshlockout starting up
          Nov 2 13:25:10 sshlockout[53783]: sshlockout starting up
          Nov 2 13:25:10 sshd[53780]: Accepted keyboard-interactive/pam for root from 192.168.63.17 port 37126 ssh2
          Nov 2 13:16:15 dnsmasq[5943]: reading /var/dhcpd/var/db/dhcpd.leases
          Nov 2 12:16:05 dnsmasq[5943]: reading /var/dhcpd/var/db/dhcpd.leases

        It should have done a renew.  Wouldn't this show in the log?

        Thanks for any help/info,

            Same here version 1.0.1 is not renewing address it has to be a  bug that carried over from 1.0 to 1.0.1 I didn't have the problem with any of the RC releases..

              As a workaround I added the following crontab entry:

              1 0,4,8,12,16,20 * * * /sbin/ifconfig vx0 down ; /sbin/ifconfig vx0 up ; /sbin/dhclient vx0

              Since doing this, the same day as my original post, I've not lost the WAN IP address.

                But what has been changed in the dhclient since the RC release?

                    I can't comment on the pre/post RC release behaivor as 1.0.1 is the first version of pfSense that I've used.

                      Hi !

                      Looks like the problem still exists, my WAN link droppes the DHCP ip address on a regular basis, and i need to click the Renew button to get it up again.
                      I´m using pfsense 1.0.1 with the latest snapshot.

                        i've got the same issue..
                        not only is it getting really anoying, but im starting to get in shit for it (company not appreciating this) and i may have to switch to a firewall that doesnt drop the ip address… would be a shame because i love everything about pfsense

                          Me too…

                          1.0.1...

                          My WAN goes down and I check the WAN interface and it's I.P. is all 0's..

                          Quick renew fixes everything..

                              both are adsl links

                                Having the exact same problem.

                                Have been using pfSense 1.0.1 but changed yesterday to 1.0.1-SNAPSHOT-12-06-2006. I have had this problem along time and it's not related to my upgrade of firmware. The problem occurs when my ISP is braking my connection in some way. Happens.. maybe.. every 2-3 month.

                                    I am copying up a new image for you all to try to http://www.pfsense.com/~sullrich/1.0.1-SNAPSHOT-12-12-2006/

                                    It will be done in a few hours, please double check the file size is not changing before downloading!

                                    However!  You need to reinstall before using this or you need to update /etc/crontab to: http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/etc/crontab?rev=1.21.2.9;content-type=text%2Fplain;only_with_tag=RELENG_1  (notice the tabs, not spaces!)

                                    If you decide to simply update /etc/crontab then you need to issue a killall cron && cron from diagnostics/command to restart cron after updating.

                                      Thanks alot for the snapshot. I was looking forward to a solution! I've got the same problem as mentioned in this thread with my swiss isp cablecom. Happened every other day, so we'll see soon if it'll work or not.

                                      Cheers

                                          Excellent, while reading your post the wan failed:
                                          Dec 13 16:21:28 dhclient[270]: exiting.

                                          Manually had to press "renew" to get it working again.

                                          Annoying problem.

                                          Cheers
