The main function of SRBox is to enable viewing and editing of firewall rules across all OPNsense instances without having to log into the OPNsense web interface.

Moreover, it is possible to create rule templates (sets of rules) that can be combined and quickly applied to each instance.

If you modify the template later, the system shows you the differences and allows you to update the rules on each instance with just one click. You also have an interface that summarizes the different templates of each instance and indicates if they need to be updated.
