I just turned off both firewalls (scary), but the backup still didn't work.
on one hand that points to a port forwarding issue (like mode in the router that is mis-set to override forwarding of individual ports?) or just a complete foobar in the lacie (thinking about your previous comment, its interesting that there is a www access mode that works fine and shows files on the drive. Meanwhile the backup appears to work entirely on the private side of the router...and fails).
I am more and more confused and more suspicious that the drive is flakey.
Sigh.
