[cs615asa] Traceroute shows * * * at the tail

Hi all,
I find in some case,  tracerouting in command prompt will output several *
* * lines at the tail, I guess that is because the firewall blocks the ICMP
return packets. But when I traceroute it in virsual trace route, it can be
reached.
Is it because they use different trace route path? Some routers block the
ICMP packets, while some not?

Thank you
Yanqiao
