      I have some sites with cable modem and pfsense.  When ISP or cable modem is acting strange (reboot or outage), lot of the times pfsense doesnt recover nicely.

      I know that the cable modem is handing out an ip in the 192.168.100. range during the first xx seconds . I configured pfsense to reject  these leases in the wan interface settings.

      But still, it didnt seem to work for me

      DHCLIENT (10394) exits first, i think when the modem reboots
      DHCLIENT (61035) gets some offers from 192.168.100
      DHCLIENT (70389) also gets some offers from 192.168.100
      DHCLIENT (70389) pfsense gets the same WAN ip just before the ISP failure

      BUT, internet doesnt work  :(

      i have seen some posts, where that say the timout values can be changed..(hardcoded)

      IS that what i have to do?

      thanks,
      TOm

        The 192.168.100.x that the cable modem is giving out is actually due to the connection on the cable interface being down.  The cable modem (specifically motorolla) will 'unbridge' when the cable connection is down and then give out an IP in the above subnet.  You do not need to do anything usually, once the cable connection comes backup, it will register the pfsense wan interface 'mac address' to the dhcp server on the cable network and update the ip adress to the current wan ip given by the cable companies dhcp forwarder.
