    If i understand you the only problem is that your server does not reply ping commands, then check your firewall setting. Seems your server's firewall blocks icmp packets.

    Most routers do not support loopback. If you are attempting to ping the external public address from the local network behind the router, it will not work. You must use the private address. One way around that is to put the private address in the HOSTS file, which will over ride the public address supplied by the DNS.

    I think this might be the problem. But is their any other alternatives for getting ping from public address.
