Hey all,
Im quite new to MQTT. So far I have only used mosquitto in local network without username and password.
What I want to aim to try and do is if mqtt is connecting to broker on local network it does not require username/password. But if connecting to broker from outside network it requires username and password.
Is there away to do this?
Broker is on rpi. Mosquitto version 1.5.7

Thanks All

Yes that is possible, but you might have to apply some firewall rules to help out.

# This setting means that all listeners have their own authentication/access control settings
per_listener_settings true

# Define our listener for external connections, with password
# authentication
listener 1883
password_file /path/to/password_file
allow_anonymous false
# If you need TLS encryption:
# cafile /path/to/certificate/authority/certificates
# certfile /path/to/server/certificate
# keyfile /path/to/server/key

# Define a listener that binds to, which means only clients
#  on the local machine can use it to connect. No authentication required. 
# This isn't usable for the wider local network though.
listener 1884

# Define a listener with no authentication. Because this has a separate port
# to the external listener, you could use some firewall rules to disallow access
# to clients that did not originate on your local network. 
listener 1885

Does that help?
