I set up the camera roll backup on my iphone to sync all my phone photo to a iMac, and according to the FAQ, i turned off relay, tracker and DHT to limit the traffic within the home LAN only. however I found it not working, i took a new photo on the phone but it doesn't show in the sync folder on iMac. As soon as I turn on the tracker option in advanced, all the new photo sync like a charm. So does this LAN only thing real?
