Hello All, I've poked around and apologize in advance if I've just missed this topic somewhere. My setup, all with BitTorrent Sync 1.3.94: A: QNAP TS-419P II B: Windows 7 PC on LAN with NAS C: Windows 8 PC at work connecting via internet Same information is being synced on each machine: "Music" and "Photos" folders I am a former MCSE and have been using Allway Sync on LAN and USB prior to this project (and still do for some tasks, but only under manual control). A to C was set up first by giving C the secrets from A, Then installed on B, using the A secrets. All folders are Full Control, since I modify files on B and C, with A being the RAID backup What I observe is happening in the BitTorrent Devices tabs on the Windows boxes: A <->B (fine) A <->C (fine) B <->C (huh?) Never gave B the secrets for C, and yet there is traffic between them, which seems redundant and kind of annoying. Is a V-shape sync pattern possible with BitTorrent Sync? There is *something* I'm missing... Thanks in advance, -G
