Network utility snap

I can't ping my mountain lion from the LAN, but my mac can ping any machine in the LAN.

I was digging into why this could be happening, I found that in network utility, in Netstat, it shows like gateway is localhost and Flags are UHS. This seems wrong. How can I change this to have my MAC address.

Your help would be appreciated.

A computer always reaches its own IP addresses through localhost. If it sent a packet to its MAC address, who would send that packet back to it?! – David Schwartz Jul 3 '13 at 7:46
Looks like Mountain lion issue but only in certain machines. – Antony Jul 5 '13 at 6:42
You might have Enable Stealth Mode ticked in the Firewall Options section of your Security % Privacy settings – Joop Jul 5 '13 at 10:29
I confirm that I don't have stealth mode enabled in my firewall section. – Antony Jul 5 '13 at 12:44
