@Zahid1991 also having this same issue with the TR605. Every day a string of "Detected large ping attack, dropped x packets" pretty annoying

@mickeys I have the same issue on an ER605 with multi-wan connections, no details and ICMP echo response is turned off.

The maximum number of consecutive dropped packets was 4. I detected that many times and increased the value to 5 for better protection against such attacks. So, administrators of networks that have high bandwidth and fast Internet should consider the last value to be configured carefully. I lost my website  https://activeoperate.com/
