The cool thing about Syncthing is their public network of community provided relay servers https://relays.syncthing.net/ https://relays.syncthing.net/
When two devices can't find each other on the local network they look for each other on public discovery servers and then pick a community provided relay to connect. The data is end-to-end encrypted between both devices, so the relay doesn't see the file contents. This works out of the box on almost all networks. Unfortunately IPv6 doesn't seem to work with their public relay network though...
- 1vuio0pswjnm7 5y agoOnce the devices have discovered each other is it necessary for the traffic to pass through syncthing servers. Once each end has discovered the address:port of the other, then the devices can connect directly. I use a different peer-to-peer solution, older than syncthing and open source, and it does not send traffic through a supernode by default, it only uses the supernode for discovery.
- BitPirate 5y agoThe use case of IPv6 relays isn't that strong to be honest. You don't have to deal with NAT and Syncthing can use UDP hole punching if the firewall doesn't completely block outgoing UDP traffic.
