Interesting. I was running pfsense since 2006 on a P4 box with PCI Intel pro NICs + WRT54G on DD-WRT, then on an AMD Geode-based HP thin client with an expansion board to give it PCI-E to use a Pro1000&#x2F;MT card + Cisco Aironet 1200 from eBay that someone flashed LWAP FW onto and couldn&#x27;t fix so they sold it as parts&#x2F;not working ($50 IIRC, had to track down the right firmware, took a day of messing with it), and finally now an ERLite + Airport Express + Ubiquiti AP AC Pro.<p>Power usage on the P4 sucked (&gt;100w idle). The eBay thin clients did much better, usually around 20-40w, and the ERLite is lowest (and it&#x27;s fanless). I ran a Cisco 2651XM for a while before any of this, but it maxed out doing NAT slower than my home connection was. Honestly though, I was just super excited to get something off-the-shelf for $100 that was stable, supported, low-power, and didn&#x27;t require much administration. Messing with this stuff was a fun hobby and I learned a lot, but now I don&#x27;t have as much time and it just needs to work.
