Using relay transfers
This feature makes it possible to use the client without configuring your router and firewall, but requires a connection to a server. Both devices need to have relayed connection activated to make it work. Most routers and firewalls allow outgoing connections and responses from the device which was contacted. A relayed connection is established from both sides to the server. The server connects both devices making it possible to transfer data even if no incoming connections are allowed on the default or configured data port.
 Relayed connections are enabled by default.
To disable relayed connections:
- Enable the Advanced Mode.
- Click on Preferences in the main window.
- Click on Network.
- Uncheck the Enable relayed transfers checkbox.
