Syncthing ist just conecting in home network

Hi, me Syncthing is runing on one PC one Laptop and one Phone. If i am at home in the home network al devices are syncing. if i leave the home network syncing aborts If i am using the Laptop over tethering of the phone the Phone is konected to the Laptop but the PC at home stays offline.

Regards Ric

Hi UPnP is aktivated, port 22000 is forwarded PC is still not conecting to mobile phone autside of home net

If you are mapping ports manually, there is no need to use UPnP, but you seem to have UPnP mappings on 3 different IP’s hence not sure if the manual mapping is correct.

Next step is trying to connect to that port from outside to verify that the router properly forwards it, also make sure global discovery is enabled on both devices.

I have now an ASUS Wireless Router RT-N66U and the same problem remains that i had with the Netgear router, no conection outside of the home network.

Can someone help me with the configuration of the ASUS router, so that it can also connect to outside?

Run syncthing with STTRACE=upnp environment variable set and provide log output.

UPnP seems to work, so I think it should be able to connect?

Yes UPnP works, but Syncthing can not be reached from outside. I am now at work, watching the computer at home through a remote connection. There is definitely no connection home. Syncthing is unlocked in Windows Firewal!

Is global discovery enabled on both sides? Also, perhaps your work firewall drops UDP packets which prevents discovery from working? You can try running STTRACE=discovery at work to see if it finds a valid IP address for the home device.

Yes global discovery is enabled on both sides and at work i am mobile online. How shoud i run STTRACE=discovery?

This is the log from the mobile conection. The Syncthing App on the mobile phone can alsow not connect to the home computer On the other hand the notebook is in the thetering network of the phone and this both recognize each other

Set STTRACE environment variable same like you did for UPnP. On the Android app there is a special option for debug options.

Can it be that the mobile provider is blocking the discovery? With Bittorrent Sync there were no problems.
