It could be your firewall settings. Try turning it off (/etc/init.d/iptables stop) and see if you can ping. If you can, then there is your answer. Either way, turn your firewall back on (/etc/init.d/iptables start) when you are done checking. If the firewall was the cause, and you have some need to ping your machine, you will need to modify your firewall settings. Read the following article for more info:

If it's not your firewall it may be dropping icmp request in the kernel itself, if it is turned on you need to turn it off with this commands:

Code:
echo "0" > /proc/sys/net/ipv4/icmp_echo_ignore_all
