We are getting ACK flood from spoofed addresses. And it get the machine's IRQD load 100% for all cores of cpu. But strange thing is TOP command showing cpu usage %0 .
We have closed TSO, GSO ....etc for offloading but nothing change.
Is there any way to solve this better ? Use the hardware cpu if the top is correct ? or how should i clean the ACK traffic instead of using ACK policier on roouter
PS : Pleas do not write talk to your isp or sth bla bla like that. We need a solution not an advice
