Recently I was changing some stuff in my cluster (remote devices, not in the same LAN) in such a way that I had to edit my remote devices adresses in order to keep everyone able to connect to everyone (I don’t want to use Global Discovery). But just as I was about to make the changes, I noticed that two devices were connected, even though they weren’t supposed to. So just to be sure, I restarted Syncthing on both devices… and they still were able to connect. So I made sure that Global Discovery was disabled on both sides, set both of their remote adresses to dynamic and restarted once again… and they still were able to connect !
Am I missing something here ? How is this even possible ? Strangely, while the ports are forwarded on both sides, it is always the same that acts as the client, no matter what order I restart the devices (to trigger the connection from a specific device).
I don’t know, but you can figure out. Since the connection is made client->server, look at the side that considers itself the client. Pause the device. Look at and hover over the addresses to see their origin. Screenshot.
Well I don’t get it : between the time I posted and now, I had configured the remote adresses (just to be sure that they stay connected) and right now I removed them to follow your instructions and I didn’t even have to restart (just pause-unpause) : they now can’t connect.
So everything seems fine, but there might have been a small glitch with the discovery caching (fixed by changing the settings once more saving), don’t you think ?
Anyway, thanks for your help and for this amazing piece of software in general : this is one of the best tools I’m using on a daily routine !
