Is there a difference in the output of route between 6.1 and 6.2?
It sounds like you may not have a route set up for the internal network.
Ping would fail both ways because the Linux box would try to send the
packets out the default route. It would send all traffic for the windows
box out the wrong interface.
A quick way to check this is to do an ifconfig, then ping the windows box,
and another ifconfig. See what interface the transmit count goes up on.
