      @stephenw10 Thank you for your time on this. I will not have physical access to the device until Friday or Saturday. I will try it again and let you know what happens asap.

        @stephenw10 This was the result of ARPing the gateway's mac

          I assume that's after it stops responding? Does that ARPing work initially?

          Did you try setting a lower max_age value?

            @stephenw10 ARPing does not work initially, neither did lowering the max age value.

              Hmm, the gateway doesn't respond to ARPing even when you are still able to reach external hosts?

                  Hmm, then maybe it's blocking something immediately but continues passing traffic until it's ARP entry expires.
                  Hard to think what that could be given you are no longer pinging it....

                    @stephenw10 Sorry for the late reply. Life got a bit crazy there for a moment. I have tried a different switch in-between the Pfsense box and the ONT. Unfortunately I got the same result. What be the next step for support at this time since we seem to have exhausted our abilities here? Should we look into purchasing support from negate on this, or do you think that there is nothing that can be done at this time?

                      Hmm, I'm not sure what more they could do here. They could re-run those tests to check the data. But what you did seems good.

                      Both the 1100 and 4100 have interfaces with quirks that could be causing issues here. If you can I would try connecting a very generic pfSense CE install to see if that also behaves the same. Some hardware with Intel NICs if you have it.

                      Reading back I was almost sure it was going to be that ARP timeout value You could try setting that to something very low like 60.

                      Steve

                          The default settings on the 1100 and 4100 should be fine there. Hard to imagine that preventing ARP. But easy to test...

                            @stephenw10 I will try both of these things as soon as I am able, but that probably won't be until Sunday.

                              Thank you both for the suggestions. Unfortunately, I got the same result after trying both suggestions. I did notice that if I unplug, and then replug the cable the interface comes back online for a while, but eventually does go offline again. I do not have any other hardware to test with atm.

                                @stephenw10 said in Not getting a DHCP WAN IP Address on netgate hardware.:

                                The ISP gateway may not appear in a traceroute.

                                The gateway's address might not appear. However, if it doesn't the hop still does and is indicated by an "*".
