[How To Use Bittorrent Sync As Pure P2P System]

Hi,

 

I installed Bittorrent Sync 1.4.110.

I read some topics regarding privacy, and I understand hash is not privacy data.

 

But I would like to use Bittorrent Sync as pure P2P system.

 

Share(mail,copy,QR code) will use internet connection(https://link.getsync.com/~).

So I will use "copy key" in settings.

I disalbed both "use tracker server" and "use relay server".

 

I believed this will work pure P2P system.

 

But I found my firewall logs continue to show connection between

ec2-54-225-196-38.compute-1.amazonaws.com UDP 3000 and my local pc.

How can I stop this?

 

To disable "use relay sever" does not work?
