Does syncthing work when UDP is blocked?

Support
1

I would like to use syncthing over WAN where another device has UDP ports blocked, would that work?

2

Yes. Syncthing can work over TCP connections.

If I’m not mistaken, UDP is only used for discovery. You only need 22000 over TCP to have sync over WAN work

4

We support both. By default 22000/tcp + 22000/udp

Thanks for answering everyone.
