Unfortunately, in my test environment, the Fritzbox in front of the UTM forms a single point of failure. The existing UTM installation is extended by a ... Read more
In the previous articles, a very small Exchange organization was set up and the question was raised as to whether an environment for a higher number of users and better availability can be subsequently created from this. A higher number of users can of course also be mapped with a Singe Server solution if the resources are sufficient. In the case of ... Read more
