Amen, brother. Someone like your CEO at somewhere like his lake house at the end of a dodgy DSL line from Cletus's ISP and Bait Shop.

There are a lot of unpleasant failure modes to blocking ICMP without completely understanding the implications.

I agree… but some folks seem to think blocking ping and traceroute give you some kind of extra security.
