Hi,
from the log of the firewall i can see attack detected from a specific IP




So i decided to add the ip in the blacklist in the reputation filter



But still i see the even in the log.


Am i doing something wrong?
Thanks in advance.

    Hi @xkp68

    Your ATP device’s ADP feature already drop abnormal TCP attack sessions from source IP of 104.173.79.233.

    So, you can see those messages shown on the log. It’s normal.



    And if you configure Black List on IP Reputation mean that the client behind LAN can’t access the IP of 104.173.79.233.

    If you would like to reject any traffic from this IP, you can add a security policy.



    Thanks.
