      More detail needed. What are you bypassing? The AT&T router? By just replacing it with a switch?

      AT&T often requires elaborate workarounds to remove their device.

      Are you sure the iMac pulled a valid DHCP lease?

        Ok, I am taking a netgear unmanaged switch. Then I am hooking up the cat5e cable from the ONT and putting in one port. Then I plug in the ATT's RG, BGW210, into another port and powering it up. Then after it gets connected and everything is initiated, I am disconnecting it from the switch. I copy the MAC address of the BGW210 and paste it onto the WAN config of the Pfsense firewall, before shutting down to get ready. Then hook up the Pfsense firewall to the switch and power it up. I've tried waiting a while for Pfsense to get an IP, but it will not get one. If I do the same to my Imac it will pull a valid IP from their DHCP server. So yes I am essentially trying to bypass the ATT router.

          I figured others might have had success in the forum spoofing the MAC address and might have some insight on something I might can do different.

            Yup. Not as easy as that. See: https://github.com/MonkWho/pfatt

              That's why I said dumb switch method, because some have had success the way I am trying without having to do pfatt. Now granted, if the power goes out I would have to plug up the RG back up to reinitiate a connection with the ONT.

                Ah, OK. Well if the Mac really is pulling a valid lease it should be possible for pfSense to do the same. Check the dhclient logs. Run a pcap on both and compare.

                  Does your AT&T router not have a passthrough option so the pfSense gets a public IP?

                  Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                  When upgrading, allow 10-15 minutes to reboot, or more depending on packages, and device or disk speed.

                    It does, just trying to getting away from the double NAT.

                      Please forgive me, but do not know linux that well. I am in ssh and it keeps telling me access denied when I try to type /bin.
                      [2.5.0-DEVELOPMENT][root@pfSense.localdomain]/root: /bin
                      /bin: Permission denied.

                      Is there a reason why I do not have permission? I'm thinking of trying the pfatt.sh route for running ATT bypass.

                        /bin is a directory, try "cd /bin"
