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

How do you spell cooperation? Pessimists use
each other, but optimists help each other.
Collaboration feeds your spirit, while
competition only stokes your ego. You'll
find the best way to get along.
