How does the ProfitBricks cloud firewall work
The firewall offered in the DCD can be used for the simple protection of a host behind it. Once activated, all incoming traffic is blocked. Only traffic on the ports explicitly enabled is able pass through. Outgoing traffic is generally permitted. In principle, we recommend that you configure your own firewall VM, even for small networks. There are a number of free options available, such as IP tables for Linux, pfSense for BSD and various solutions for Windows. Please address any questions to our support team.
