Hello, i'm suffering an attack, that causes my Rx packets go high. Can you give me some suggestion to solve this problem?
Need more info about the attack and your WAN router (model etc.), and WAN link, ISP, country.
Your ISP can also route the traffic to blackhole on their router --> talk also to your ISP.
If the attack is moderate, then that you could block in the firewall of your WAN router if the attack has a certain structure (IP group, port group, protocol(s) etc.)
