acurcione Posted March 31, 2014 Report Share Posted March 31, 2014 I'm trying BTSync to sync on my local network between a NAS running unRAID and a Mac Mini. In my initial tests everything worked fine. Since I'm ONLY running this locally I figured I'd turn off UPNP on both ends since I don't think it's needed (unless I'm wrong). When I turned it off on my Mac the port mapping disappeared like it should on my router. However after I disabled it on my NAS (which is a Linux derivative), not only does the port mapping still appear, it shows a new one every time I restart the service! So the old mappings are there along with new ones. I have no idea why it's still using UPNP when I've told it not to or why the old mappings aren't releasing. Ideas?

acurcione Posted April 1, 2014 Author Report Share Posted April 1, 2014 Thought I'd let you know that the desktop application on my Mac is still mapping the port even though UPNP is disabled. So I'm guessing there's no way to keep these things from opening ports to the outside even if all I'm doing is internal syncing? Quote Link to comment Share on other sites More sharing options...
acurcione Posted April 1, 2014 Author Report Share Posted April 1, 2014 I just found the FAQ about keeping all traffic on the LAN by disabling several settings. However even with these settings off on both machines AND UPNP disabled, ports are still mapped. And if that weren't bad enough, I see outbound connections on my router to god knows what originating from the ports used on both machines: udp 192.168.1.100:60668 54.225.92.50:3000 UNREPLIED udp 192.168.1.100:60668 54.225.100.8:3000 UNREPLIED udp 192.168.1.75:14524 54.225.92.50:3000 UNREPLIED udp 192.168.1.75:14524 54.225.100.8:3000 UNREPLIED This is more than a little disconcerting. Can anyone please elaborate on this and to why the apps are continuing to map ports? Does it have to map ports even for LAN? And what the heck is it trying to connect to here?

GreatMarko Posted April 1, 2014 Report Share Posted April 1, 2014 I see outbound connections on my router to god knows what...Both 54.225.92.50 and 54.225.100.8 are BitTorrent Sync tracker IPs (For 54.22.92.50 have a look at this thread. and for 54.225.100.8 have a look at this post) Quote Link to comment Share on other sites More sharing options...
acurcione Posted April 1, 2014 Author Report Share Posted April 1, 2014 In relation to 54.225.92.50 and 54.225.100.8 are BitTorrent Sync tracker IPs For 54.22.92.50 have a look also at this thread. and for 54.225.100.8 have a look at this post. Thanks for that. I had a feeling it might be for stats or something, but I couldn't find anything on it. Maybe this should be added to the FAQ. And that also explains why the ports are still mapping since it has to have some way to communicate. Again, should be added to the FAQ so folks know what to expect. Thanks again.

RomanZ Posted April 2, 2014 Report Share Posted April 2, 2014 acurcione, BTSync also uses NAT-PMP to map ports, which is not disabled by the checkbox in preferences. I suspect that your router supports NAT-PMP and that's why is actually mapping ports. Quote Link to comment Share on other sites More sharing options...

As long as it's nothing nefarious, I'm ok with it. Great software, BTW!Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
