Enable access to agents outside the corporate network (MQTT)

Remote control of agents is always possible with direct network access. Additionally, by using the MQTT protocol, agents can be accessed behind firewalls or outside the corporate network. MQTT is enabled by default, but requires CPU and RAM resources on the DES. Therefore, if there are a large number of agents, it is advisable not to activate MQTT across the board for all agents, but only for those that cannot be reached via direct network access. Load balancing can take place through the use of Linked DES servers.
