      The reason I hardcoded it is that I have an high availability setup. Right now the LTE modem is connected to my secondary pfsense, but I want to me able to move the connection to the primary if necessary. I know that having the same MAC address can make it a seamless transition.

            @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.
