In my eyes syncthing-fork behaves like a virus.
I installed both syncthing and syncthing-fork on my android phone.
I have also installed AFWall+ and disabled (but logged) all network access for a test. I disabled NAT traversal and global discovery!
Here is my result:
While the original syncthing is only accessing my local network (what it should do) the syncthing-fork tried to reach a lot of unknown destinations in the internet (which it should not do). I can’t trust this app - I think it might be dangerous.
Maybe it transfers all my data to a place I don’t want it to be…
Here are some destinations it tried to reach:
- 78.246.223.22:26550 (vin83-1-78-246-223-22.fbx.proxad.net)
- 185.142.227.100
- 81.153.106.170:25492 (host81-153-106-170.range81-153.btcentralplus.com)

Update
I compared it in a wrong way:
In syncthing the relay was disabled and in syncthing-fork the relay was enabled.
As soon as I disabled the relay server option syncthing-fork stopped to contact servers in the internet.
