This document provides instructions for creating a virtual machine (VM) for pfSense, an open-source firewall and routing platform based on FreeBSD. The instructions specify to name the new VM, select a machine folder and FreeBSD 64-bit operating system type. 2GB of RAM is recommended for faster performance, selecting up to the maximum RAM available depending on other active VMs. A 20GB hard disk size is recommended for the initial setup. Once configured, press start to launch the new pfSense VM in VirtualBox.
