Weird, why would anyone block ICMP on the internal network? Makes sense if they filter/block outbound/inbound requests, but internally? Makes me wanna go "yew"!

Talk about paranoid, I wouldn't be surprised if he lovingly caresses the server everyday, droning "My own, my love, my preciousss!" But tell me, why the paranoia? You're not developing software for the Defense Department or anything, are you?
