    Hi @MIKE11224466,

    Thank you for visiting SonicWall Community.

    Regarding "TCP/IP : TCP Sequence Number Approximation Based Denial of Service", please try to enable the highlighted check boxes in the SonicWall appliance.

    For the other two scan results, please check if the port TCP 81 is assigned to the SonicWall's web management or port opened to a local host behind SonicWall.

    Hope this helps. Keep us posted.
