[ale] Dual NICs doh!

[ChangingLINKS.com]

Man, I didn't check my internet connectivity before posting my celebration. I 
found out that the bond0 only works on my LAN. I tried using BOOTPROTO=dhcp 
and it failed.

Where do I start? Everything seems to look fine. And, I removed each cable, 
and still had LAN constant pinging of the LAN. So, it seems as though my 
bond0 is set up correctly - but, I cannot ping yahoo anymore -
