Ok, maybe it isn't my routing table.
Netstat -r returns -I left off col heads.

192.168.1.0   *   255.255.255.0   U  0  0  0  eth0
169.254.0.0   *   255.255.0.0       U  0  0  0  eth0
default           192.168.1.1 0.0.0.0 UG  0 0 0 eth0 

In the gui for eth0 the Gateway entry is 192.168.1.1 which is correct.
I don't seem to have a loop back entry.

Also if this helps, I am on a Static IP in my LAN at 192.168.1.51

As to my router, it passes traffic from a couple of Windoze boxes to the
Internet just fine; you're reading this email <grin/>. The Win boxes can
ping the Linux box and the Linux box can ping the windows boxes. What it
cannot do is ping an IP off the LAN nor say  a name www.yahoo.com.  I
don't think this is a DNS issue yet as like I said I can't ping IPs off
the LAN.

What am I missing here?

THANK YOU!
