Connection Type¶
The Connect Control Service provides Endpoint connection types for a variety of use cases and networking contexts.
The available options are:
Auto: the Endpoint decides whether a relay is appropriate based on the NAT in use. When adverse NAT conditions are detected, a relay is used to work around them.Direct: outbound traffic from the Endpoint does not go via a relay, unless a peer requires a relay for connectivity.Open Public Port: the Endpoint has a fixed, publicly-accessible port to allow peers to reach it directly, even if a peer usually requires a relay; see How to configure an Open Public Port.UDP Relay: the Endpoint uses a connection relay for all TAN traffic; useful when the NAT type is known and is unlikely to change.
New Endpoints default to the Auto Connection Type. This can be changed, as
described below.
Encrypted data
Your data is not, and can not be, decrypted by the connection relay as it never has the decryption keys.
Configuring Connection Type¶
Required version: 3.2.0 or higher
The client must be running version 3.2.0 or higher to use this feature.
The Connection Type setting for Endpoints registered prior to release 3.2
will not default to Auto. Please check the Connection Type setting is
correct, even if the Endpoint has since been upgraded.
In the Control Service, navigate to the Settings tab of the Endpoint within your Organisation and click on the Edit Settings button.
Choose an option from the Connection Type drop-down list, then click on the Save button to save the change.
The setting will take effect immediately; there is no need to restart the Endpoint.
Tip
UDP Relay mode only needs to be enabled on Endpoints which require a relay; peers will automatically use the relay when required.
