Regarding:
Also, in the TM specific help screen for LS Duo, I can't find where to do this step:
"Enter the Mac’s “Computer Name” from its sharing page as the [Target Host Name]. For the [Target MAC address], enter the Mac’s Ethernet ID from Advanced Settings in its Network Preferences page. Click [Apply]. "
Where is this in the web config page??? Under Extensions-Time Machine, you can just choose the target folder. There are no other fields in which to enter the Mac's Computer Name or the Mac's Ethernet ID.
I had the same problem.
The model LS-WV2.0TL/R1 manual I downloaded from the buffalotech site has instructions for setting up Time Machine starting on page 65. On page 66, step #7 discusses entering Target Host Name and Target MAC address but I couldn't find a place to enter this data. After some trial and error I decided to skip step 7 and went directly to step 8 and everything worked fine. Maybe the downloadable manual is for another version of OSX ?
