Enjoy the situation!  You've been tasked with an exciting project.

1. Disable the firewall.  Perhaps the ping packets are being dropped at
   that level?

2. If that doesn't help, please post the output of

    route -n
    iptables -vnL
    ifconfig -a

There's no way we can debug you issue wiithout that information.
