Can't ping behind LAN

[ktoddsd]

I have a linux box that can ping all nodes on LAN, but can't ping anything on the internet. My gateway is 172.16.0.1, My IP is 172.16.0.13 All other nodes can ping out with that gateway set. Can you guys tell from the following info if I have something set wrong?

It's probably being filtered by your firewall. Ask your network admin.
