We are having attacks from outside to DMZ. Many diffrents ips are attacking our public range. These attacks are causing packet buffer 100% and CPU 100%, doing an outage in our network. So in traffic logs we can see all sesiones being denied for policy deny. Is there any way to avoid that FW proccess these sessions and not increasing CPU?? what actions can be taken in FW?
Yes, i enabled but i think with the default paramethers is not helping a lot.
I attach a screenshot where you can see the sessions. Many sessions from differents ipsin the same second.The most of sessions are using the ports 744 and 736.
Any idea for not proccessing these sessions? to avoid impact in CPU
