Hi All;
We are experiencing DDoS UDP Attack from a single ip. The IP is already in drop list. However, we are still getting down due to high CPU load on one single core.
Here is the Screenshot:
We set up an allowed ip list. we store all legit user ips in there. Our usu[/img]al CPU Usage is 30%. Our users lost connection after getting one ip flood attack due to high cpu usage on single core. However, Not all our users lost connection only users whose ips pogress or checking by the cpu that reach 100%.
How can we handle this situation or fix it.
Thanks in advance.
