What are ICMP packets?
What will be an ideal response?
ICMP rules are especially important because ICMP packets can be easily forged and used to redirect other communications. The most common ICMP command is Packet Internet Groper (commonly called ping). The command determines if a host is unreachable on the network. You send a packet to a host you're trying to reach, and the host responds with an ICMP response packet that tells you the host is "alive. " Many attackers begin attacks by using ping to see whether a host is reachable by them as well. If all of your hosts respond to the ping command, you could be opening up your network to an attack.
