- I am under DDoS. What can I do? 4 answers
I am configuring Config Server Firewall and here is the default config for ICMP. I have read on the internet that disabling or limiting ICMP can cause huge headaches on your server. However I have also read it can help prevent some times of DDOS.
Do you think i should rate limit and if yes at what rate?
# Allow incoming PING ICMP_IN = "1" # Set the per IP address incoming ICMP packet rate # To disable rate limiting set to "0" ICMP_IN_RATE = "1/s" # Allow outgoing PING ICMP_OUT = "1" # Set the per IP address outgoing ICMP packet rate (hits per second allowed), # e.g. "1/s" # To disable rate limiting set to "0" ICMP_OUT_RATE = "0"
