gunverth Posted November 17, 2015 Report Share Posted November 17, 2015 We are setting up a another BtSync-based distribution system at a public school for teachers and students. This usually works very well and is a efficient way to push files to students. The teachers puts the files which would be used for classes and homework in respective folder on their Mac and everything is synced to the students iPads. Everything is fully legal. We have now seen at a new installation that the iPad peers are coming from the IP address 67.215.231.242 instead of their real NATed IP address, when they are on the school network. The iPads also loses their peer name. Everything is working fine though. When the students are at home everything looks and works fine.67.215.231.242 is "relay-02.utorrent.com" so I suspect there are no surveillance activities going on. Any hints of whats going on? It´s a cosmetic problem anyway. Quote Link to comment Share on other sites More sharing options...
iswrong Posted November 17, 2015 Report Share Posted November 17, 2015 This typically happens when both sides are behind a firewall and no ports can be punched open through NAT-PMP. Perhaps the teachers' iMacs are also behind NAT? Quote Link to comment Share on other sites More sharing options...
Helen Posted November 17, 2015 Report Share Posted November 17, 2015 gunverth, Yes, this is relay server, which helps peers to connect when direct connection it not possible. As iswrong indicated - it happens when peers are behind firewalls, NATs, etc. No, there are no surveillance activities going on. Quote Link to comment Share on other sites More sharing options...
gunverth Posted November 17, 2015 Author Report Share Posted November 17, 2015 OK. Here's a probable explanation: the IT dep has just started isolating all WiFi-clients (the students) and only allows a route to the Internet.More so they have blocked contact with all public Bittorrent servers, so we are running BtSync clients through a delegated socks5 proxy. This school has free rein with their IT so it's kind of counterproductive to block what they have chosen themselves. Quote Link to comment Share on other sites More sharing options...
