[olug] Backing up Linux through NAT

[Dan Linder]

If you can ping the "Server(A)" from the Linux box, then the mapping and
other network traffic should work too. (Provided the WinXP or Server(A)
firewalls permit the SMB communication.)

And about using the XP system as a "drop box" point, that should work too.
