        GOT IT:

        There is an error in the FreeBSD implementation of dhclient. If I substitute the 70 dhclient with the 80 ditto the protocol runs smoothly

        arc01fw03:/var#  ./dhclient -d sis3
        DHCPREQUEST on sis3 to 255.255.255.255 port 67
        DHCPACK from 79.142.231.1
        bound to 79.142.231.106 – renewal in 150 seconds.
        DHCPREQUEST on sis3 to 79.142.231.1 port 67
        DHCPACK from 79.142.231.1
        bound to 79.142.231.106 -- renewal in 150 seconds.

          I don't understand what you mean by the 70 dhclient. Would you please explain?

            I mean the /sbin/dhclient executable which runs the dhcp client logic.
            If I replace this executable (which is based on FreeBSD 7.0 for pfSense 1.2.2) with the FreeBSD 8.0 executable it works as my previous post indicates.

            As of now the 8.0 dhclient has renewed successfully without broadcast for 8h :-)

            So now I just need to find out how to replace dhclient in /sbin which is R/O on my CFCARD. Right now i killed the /sbin/dhclient and run the 8.0 version out of /var on the pfSense command line.

            Thanks

              Understood, thanks.

              Have you tried pfSense 1.2.3, which is rather more up to date than pfSense 1.2.2?

                Actually I'm awaiting 2.0 but maybe this was a wrong strategy.

                Also found http://www.pubbs.net/200902/freebsd/23740-dhclient-cant-renew-lease.html which suggests replacing the 7.0 dhclient with the 7.1 counterpart.

                Is 1.2.3 FreeBSD 7.1 based ?

                    I just installed 1.2.3 Nano 2G image on my CFCard and except for problems assigning interfaces to WAN and LAN and LAN IP address using the console (it ignored my input :-/) I managed to restore my configuration by assigning IP 192.168.1.2 to my own machine.

                    Now everything - including dhcp - seems to be fine :-)

                    Thanks for the input !!

                      UPDATE:

                      Upgrading to 1.2.3 was not enough to remove the failures renewing directly.
                      However substituting the /sbin/dhclient with the dhclient from FreeBSD 8.0 did the trick.

                      Thanks

                        Anyone have a copy of dhclient from 8.0 that they'd be willing to send me?

                        Thanks in advance, and much kudos to cb831!

                        edit: I got impatient so I downloaded the 220MB iso to extract the 77K file ;)

                        It appears to be working, I'm now getting:
                        Aug 16 17:30:35 dhclient[63382]: bound to 99.99.207.xxx – renewal in 300 seconds.
                        Aug 16 17:30:35 dhclient[63382]: DHCPACK from 99.99.206.xxx
                        Aug 16 17:30:35 dhclient[63382]: DHCPREQUEST on vlan0 to 10.0.0.1 port 67

                        Instead of:
                        Aug 16 17:11:03 dhclient[18353]: bound to 99.99.207.xxx – renewal in 300 seconds.
                        Aug 16 17:11:03 dhclient[18353]: DHCPACK from 99.99.206.xxx
                        Aug 16 17:11:03 dhclient[18353]: SENDING DIRECT
                        Aug 16 17:11:03 dhclient[18353]: DHCPREQUEST on vlan0 to 10.0.0.1 port 67

                        Hopefully it won't be dropping now.
