Peter,

There are two separate LANs.

#1) Earthlink dynamic IP has 10 or so linux boxes and 3 Windoz 98 boxes. 
The Windoz boxes can be accessed from linux but the linux network can't be
accessed from Windoz.

#2) SBC static IP with one Windoz XP computer.  Three blank ports left on
the Netopia modem/router.  I can plug the camera into one of these and get
pictures on the Windoz machine.

I would like to move everything to the SPC static IP modem.

Tom
