5.6.1 General Settings
The “Blind address” option specifies whether the MQTT-Broker shall be linked with all IP
addresses of the system (0.0.0.0) or whether the service should only be accessible under a
certain IP address.
The port used by the MQTT-Broker (standard port: tcp/1883) can be specified in the general
settings as well.
At the “Maximum connections” option, the maximum number of connections can be set. This
setting provides operational safety and may protect the service from extraordinarily high loads
caused by an indefinite number of simultaneous connections. Enable the “Unlimited” check
box to remove preset restrictions.
