Building A PFSense Firewall For Your Home

Build your own Firewall/Router with PFSense.

pfSense is an open source firewall/router computer software distribution based on FreeBSD. It is installed on a physical computer or a virtual machine to make a dedicated firewall/router for a network and is noted for its reliability and offering features often only found in expensive commercial firewalls. It can be configured and upgraded through a web-based interface, and requires no knowledge of the underlying FreeBSD system to manage. pfSense is commonly deployed as a perimeter firewall, router, wireless access pointDHCP server, DNS server, and as a VPNendpoint. pfSense supports installation of third-party packages like Snort or Squid through its Package Manager.

The system is fairly light weight an can be run on old or inexpensive hardware.  For my purpose which is a home/small business router, where I want VPN capability, squid proxy server and easy router for a web server and low power draw.

I went with a Asus J1800I-A SOC system.  It is a 2.4Ghz Dual core Celeron, and out fitted it with 4GB of DDR3L ram.

I had paid $98 for the SOC, $50 for the ram, $50 for the case and $45 for the PSU.  This SOC system has a PCI port and I used an INTEL Gigabit Adapter for the LAN port (49.99 to buy new).  I also have a 120 GB SSD for the system install.

Overall the system runs between 50 and 60% load.  The Disk usage is about 500mb for the ufs, tmp and var partition.  Memory Usage runs at about 6%.  The system is fast and easy to manage.
