    Thanks but I don't see anything in that link other than a description of the problem?  Anyway, yes that basically describes it.  However it's not affecting my internet service.  

     

    I did see an old article from around 2015 where these were caused by having Access Control turned on...and I set that up at the same time I updated the firmware.  In fact Access Control was on when I rebooted after the firmware update.  Hmmm...

     

    Anyay, I am still getting the NULL attack messages as well.  I've logged an incident with my ISP.  Hopefully these are just false positives.

      Might try a factory reset and setup from scratch. This time, don't setup Access Controls or any additional features. Check the logs.

        Thanks Furry, I've thought about that.  The thing is I see two types of attacks: the LAND attacks and the NULL attacks.  The latter have a legit source IP which seem to be coming from China.

         

        I've opened a ticket with my ISP and I'm waiting to hear back from them.
