Hello RomanZ Thank you for your instruction about make btsync work in China. I modify the hosts in windows and my mobile phone over 3G network is able to recognize my windows box, but when I do the same to my fedora box, my mobile phone failed to recognize the fedora box, but if the fedora box and mobile phone are in the same local network, they can recognize each other, my fedora box is relatively vanilla one with little configuration after installation, I've checked sync.log and find 3 upnp device error, is that relevant? Is there any other possibility to make it works? P.S the nslookup result of t.usyncapp.com seems not direct to the right IP, and the binary file test get no result, but I could ping t.usyncapp.com and these three IPs successfully.
