          @mrn in Router mode i suspect the cable modem is giving out a DHCP address in the RFC1918 space which based on your screenshot, pfsense will ignore. Uncheck that option and test again.

            @michmoor Believe it or not, it STILL doesn't pull a DHCP lease.

            I'm about to return this thing and try something else.

              @mrn uncheck the two boxes for the reserved addresses on your WAN page.

                  I rebooted the modem, I rebooted pfsense. It just does not work!!

                    Desperation.
                    Try another port other than igb3

                        @mrn Quit trying to spoof the MAC address.. Not sure why you would need it.

                              Yeah could be broken in many ways. I haven't used it for anything else. Thankfully I got another spare port.
