Here's the setup: Internet <-> Mobile Phone (as Wireless Hotspot on SubnetA) <-> Router1 (as Wireless Client on SubnetA, DHCP to SubnetB) <-> Router2 (Wired Client on SubnetB, Wired/Wireless Hotspot DHCP to SubnetC) <-> Home Network PC's & Devices In this setup, Home Network PC's and Devices CANNOT BitTorrent Sync with Mobile Phone, or vice versa. All Home Network PC's & Devices can BT Sync with each other, and can access the Internet flawlessly. Is this an unsupported setup, a bug, user setup error? Please advice if there's any particular BT Sync or Router settings to try. Thanks!
