ICMP is a part of the TCP protocol. If you're going to be a good net
citizen, you =should= enable it.
Otherwise, how are your LAN clients going to do MTU discovery, or find that
a host is unreachable, or that there is a routing loop out there, or...
The only ICMP service you could make a good case for blocking is "echo
request", which could be used to map your network.
