Intel Celeron 1037U Mini Desktop Computer

When i moved to a new appartment some time ago there was already a router installed and provided by my ISP. The router was responsible for routing WAN and IPTV traffic and acted as a Wireless Access Point. However the router was completely locked down and there were no way to access it. I started to look for a replacement and quite soon I found a match made in heaven - pfSense as firewall/router on my own hardware.

In this multipart series I will show you how I built and configured my own firewall/router with Wireless capabilities and a lot more using pfSense.

What is 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 point, DHCP server, DNS server, and as a VPN endpoint. pfSense supports installation of third-party packages like Snort or Squid through its Package Manager. – Wikipedia


I found an Intel Celeron 1037U Mini Desktop Computer on AliExpress that suited me perfectly:

  • Small form-factor
  • Fanless system
  • Faily good processor power and speed and enough RAM
  • Support for AES-NI for hardware encryption/decryption that can come in handy when using VPN technologies sush as OpenVPN
  • Dual Intel Gigabit Ethernet NICs with support for teaming if needed
  • Wireless support/dual antenna with extension card
  • Cheap, about $184 plus $50 in custom (imported from China to Sweden)
