Using Win7, XP and Android devices
Maybe I am missing something?
GUI Listen Addresses 127.0.0.1:8384 Sync Protocol Listen Addresses 0.0.0.0:22000
Enable UPnP ENABLED Global Discovery ENABLED Automatic upgrades ENABLED Local Discovery ENABLED
Global Discovery Server udp4://announce.syncthing.net:22026, udp6://announce-v6.syncthing.net:22026
It should work.
Are all devices on the same subnet, does the router allow multicasts, do firewalls permit multicasts?
Netgear WNR1000v3 UPnP: activated multicast: I dont´see that.
tried everything with firewall disabled
Try setting STTRACE=beacon,discovery environment variable, and see the logs for more clues. Does it actually say that local discovery started successfully?
Sorry, I have no idea what that is and where to set that. Seems like I have to know more than I do, to run syncthing?
Everything works fine with btsync, if that maybe tells you, that the router settings are fine ?
BTSync uses a different way of connecting, so not necessarily.
If you use SyncTrayzor, under advanced syncthing options, you can just put a value beacon,discovery and restart syncthing (not SyncTrayzor) and gather the more verbose log for inspection.
Ty, but I might be not smart enough to run syncthing.

I tried Local Discovery DISABLED. No syncing anywhere.
Well, local discovery implies discovery via local network. Make sure global discovery is enabled on all devices, and at least two of them are able to get a UPnP port mapping, which is critical to be able to connect if they are not on the same network.
global discovery is enabled on all devices
Then you can run with STTRACE=discovery environment variable set, and see why it’s not finding remote peers.
DEBUG: discover udp6://announce-v6.syncthing.net:22026: broadcast resolve: GetAddrInfoW: Der angegebene Host ist unbekannt.; trying again in 1m0s
meaning host unknown
That’s fine, that’s IPv6, what about IPv4 though? Does it say 1/2 (1 out of 2) in the web ui on all devices?
1/2 (1 out of 2)

Given devies A B and C, what does Lookup for B and C look on A?
Looks like this:
A B C have global discovery ENABLED
A has local discovery DISABLED ( WIN 7 ) B has local discovery ENABLED ( Windows XP ) C has local discovery ENABLED ( Android App)
[[A] 2015/06/17 04:52:39.728200 client_udp.go:223: DEBUG: discover udp4://announce.syncthing.net:22026: Lookup© result: [my.IP:61185 my.IP:22000]

So ideally you should join IRC to that people could answer/ask questions in real time, as debugging via forum will take a while.
As I’ve explained, local discovery has nothing to do with this.
I assume A is outside of the network? Have B and C both successfully acquired a UPnP port mapping, given A is trying to connect to them?
What if I just use 2 Android smartphones, both using 3G, not WLAN, no router. Should that work?
Syncthing should just work like any software, without all this problems imo.
To bad, because I was recommending it after I found it, now I can´t get it to work.
Thank you anyway.
Have you hopped on IRC for a debugging session yet? 
I have no IRC.

it’s late in Europe at the moment, though, so the channel will likely be quiet.
