Kalin,

	Did you add a specific route for the alternative network? I know this  
may sound crazy but for whatever reason Macs don't override the  
default route automatically. You would think that any attached  
ethernet device would be considered a best route to that LAN however I  
have had experience otherwise.

Collaboration feeds your spirit, while
competition only stokes your ego. You'll
