Relaying
|
|
========
|
|
|
|
Syncthing can bounce traffic via a *relay* when it's not possible to establish
|
|
a direct connection between two devices. There are a number of public relays
|
|
available for this purpose. The advantage is that it makes a connection
|
|
possible where it would otherwise not be; the downside is that the transfer
|
|
rate is much lower than a direct connection would allow. When connected via a
|
|
relay, Syncthing will periodically retry a direct connection.
|
|
|
|
Relaying is enabled by default.

Security
|
|
--------
|
|
|
|
The connection between two devices is still end to end encrypted, the relay
|
|
only retransmits the encrypted data much like a router. However, a device must
|
|
register with a relay in order to be reachable over that relay, so the relay
|
|
knows your IP and device ID. In that respect it is similar to a discovery
|
|
server. The relay operator can see the amount of traffic flowing between
|
|
devices.
