For those of you who may be running BTSync on an Ubuntu EC2 instance, could you please shed some light on how you got it successfully running? Tuxpoldo provides a great Ubuntu apt-get install option that is easy to install and run. Steps Completed: I have set up & run the btsync service, accessed the GUI control panel, and then added folders. By setting the port to a specific number (e.g. 37076), I opened UDP & TCP Listening 37076, UDP & TCP Listening 3000 via AWS control panel for "Security Groups." My (First) Problem: After adding folders w/ keys, no connected devices are displayed and no syncing occurs. SOLVED: Unchecked "Use NAT UPnP Mapping" on client and device was seen. (doh) Current Problem: Devices are now seen. Devices show that they're uploading to other devices, but no data is sent. Recipient devices say synced without any awareness of supposedly downloading data.
