1) ICMPs are often blocked - either at network boundaries or inside routers themselves
2) an ICMP tells you only how your packets get to the destination; it says nothing about how other traffic gets there or the return path
A NAT address tells you both directions and *cannot* be hidden except by another NAT along the same path.
