Hi. everyone, I've been using BTSync on several devices for a week and never had any problems — everything works fine. The only problem appears when I try to use BTSync on my work — it does not start syncing and can't show any connected devices. Assuming the fact we have all the ports closed, except especially opened, I support the problem is in ports. So, the question is: what ports TCP/UDP should be opened for BTSync to work? Thanks in advance.
