    don't some network devices use ICMP to keep track of host topology & stuff. once you kill ICMP, you create silence. if a host is removed or malfunctioning, there is no way to tell anymore.
    ICMP's should be blocked by the firewall between your network and the internet. You will still have them within the network, but it can be very good to have the outside world hear silence when they try calling out to you

    Exactly. We have had ICMP blocked for about 5 years, no issues.
    There is only one constant, one universal, it is the only real truth: causality. Action. Reaction. Cause and effect...There is no escape from it, we are forever slaves to it. Our only hope, our only peace is to understand it, to understand the 'why'. 'Why' is what separates us from them, you from me. 'Why' is the only real social power, without it you are powerless.
