What hardware to buy for pfSense router in 2019

This article has been last updated on June 29, 2019

As you guys know we sell quite a lot of open source hardware. Most of our customers are fans of pfSense, the most popular open source operating system for routers. The question we often get is "What hardware should I get for pfSense?". 

It's already 2019, so any hardware you get must be ready to support the next release of pfSense. The upcoming version 2.5 of pfSense has one key requirement that previous versions didn't. The CPU must support AES-NI, the native, hardware encryption instructions. Software encryption will no longer be supported, so you must make sure your CPU has AES-NI.

Update: pfSense has announced that version 2.5 will support hardware without AES-NI. It is still strongly recommended that your processor supports it, but it's not a strict requirement. For details, see the message from the pfSense team.

pfSense 2.5 hardware requirements

Not everyone is the same, but there are some common requirements that any hardware must fulfill. 

  • CPU should support AES-NI
  • CPU must be powerful enough to route your internet traffic
  • CPU should be 64bit Intel or AMD
  • RAM - you must have enough for the packages you want to run. 
  • NICs - LAN ports should be coming from Intel. pfSense still doesn't perform great with Realtec Network Interfaces.
  • WiFi - pfSense supports a very limited number of WiFi adapters. If you plan on using WiFi, make sure you get the right adapter. 

What is AES-NI?

AES-NI (AES New Instructions) is a new encryption instruction set, baked right into CPU that dramatically speeds up cryptography tasks such as encryption/decryption for VPN or SSL. AES-NI was initially developed by Intel, but most modern AMD CPUs also support it now. 

There are a lot of routers sold online that claim to be pfSense compatible and don't support AES-NI. This is theoretically true because pfSense 2.4 does not strictly require it. Once pfSense 2.5 will be released, their routers will be stuck with the old version of pfSense.

All hardware sold by TekLager has AES-NI support and Intel NICs.

pfSense 2.5 release date

pfSense 2.5 development version is already released and can be used, but it's not considered stable. When we tested it in May, it was still causing some problems during installation, so we recommend to wait with the upgrade until the stable version is released

It's not yet known when the stable release will be made, but it's likely that we will see it during Q1 2020.


pfSense firewall appliance recommendations


Cheap pfSense box - APU2D0

APU is a well known, reliable hardware manufactured by a Swiss company PC Engines. APU2, APU3 and APU4 routers are the most popular hardware firewalls we sell at TekLager. There are few versions of APU, starting at entry level APU2D0, to the latest version of APU4C4.

This is the cheapest pfSense router we sell, but don't be deceived, it's a very capable firewall for home or small office.

Tip: in most applications, this box will perform just as well as the more expensive versions.

APU2D0 router

  • CPU: 4 core, 1Ghz AMD GX-412TC (with AES-NI) 
  • RAM: 2GB DDR3-1333 DRAM
  • NIC: 2x Gigabit Intel i211AT
  • Storage: 16GB mSata SSD
  • Routing throughput: 750Mbit/1Gbit on pfSense. 1Gbit/1Gbit on OpenWRT/IPFire/Linux.
  • VPN: 100Mbit over OpenVPN, 650Mbit over WireGuard. 
  • Cooling: Passive, fanless cooling.
  • Power consumption: 6-10W - very low power consumption

See the full specification here: APU2D0 router 

This hardware is definitely good enough for home usage. It's passively cooled, so it's completely silent. 

Our favorite thing about APU routers is that they are 100% silent, cheap, powerful enough and super reliable.
