Summary
In this chapter, we've learned how to configure the OPNsense system settings, create users and groups, and how to back up the system configuration. You are now able to change OPNsense settings, add users and groups with different levels of privileges, enable external authentication for remote users' authentication in OPNsense, and change low-level settings using tunables. And you can do all these system modifications with confidence by doing a system backup before applying changes.
In the next chapter, we will dive into firewalling concepts and features available on OPNsense. We will learn how to manage rules, change firewall settings when necessary, and troubleshoot common issues using diagnostic tools and logs.
