Unable to ping any website through terminal and network utility I have internet connection and I can access every website. But when I try to ping any website ( be it www.google.com or www.stackoverflow.com or any site ) I always get Request timeout for icmp_seq 0 (I tried to ping and traceroute from terminal as well as network utility but faced the same issue). Moreover if I try to ping any website which is on VPN then I get correct response ( All packet transmitted and all received no loss )

I am on VPN and behind proxy too.

What can be the issue and how to fix it?
It's highly likely pings are blocked somewhere upstream from you.
