Does checking "Enable TCP" allow non-encrypted MQTT traffic?

MQTT Distributor:

The manual (see reference link below), describes how to configure SSL/TLS encryption on the MQTT traffic received by the MQTT Distributor. The manual implies that BOTH Enable TCP and Enable TLS should be enabled. Our question is (see diagram attach for screen shot of manual reference) :

If we want ONLY encrypted MQTT Traffic to be received on the MQTT Distributor, should ONLY the Enable TLS be checked? (and therefore the Enable TCP for Non-TLS unchecked)

Hello Chris,

Yes, you are correct. If you only want (encrypted) TLS connections then select just the TLS and uncheck TCP connections.
