      Should my wan interface ip address be different to my Gateway wan-pppoe ip address ?

      wan interface ip address 82.xx.xx.xx
      Gateway wan-pppoe address 51.xxx.xx.xx

        A PPPoE configures the interface and gateway IP addresses automatically.
        Yes, it is expected that both are different.

            Yes. It shows a part of of the pppoe handshake with the authentication up to the client requesting the IP settings.
            But the log should go on at this point. You should see the server sending the gateway IP and your interface IP, and then the client accepting these settings.

              Yeah, that looks normal. It's common to see a gateway outside the WAN subnet on a PPPoE connection. It's point to point so it doesn't need to be.

                  The system and ppp logs covering the time it drops would probably show it.

                      Yes, you can mask that if you need to as long as you replace it consistently in the logs so we can still see it being used.
