In this chapter, we began by discussing networking basics using the seven-layer OSI model as a point of departure. Although not an exhaustive tutorial on networking, the first section should help provide a basic idea of where pfSense fits into the structure of a typical network. We also covered typical pfSense deployment scenarios as well as the hardware requirements and sizing guidelines. We also covered how to download and install pfSense and how to perform basic system configuration using both the console and the Setup Wizard in the web GUI. Finally, we covered some additional setup options, and how to enable SSH login.
In the next chapter, we will cover how to complete pfSense configuration, including how to add interfaces, how to set up pfSense as a DHCP server, how to set up VLANs, and how to back up and restore your system.
