Best Hardware for PfSense 2020

(Last Updated On: November 7, 2020)

PfSense, based on FreeBSD is an open-source firewall or a router computer software. It, however, can be installed on a machine or a computer to make a firewall or a router. Since configuration & up-gradation is no more a problem as through a web-based interface, you can easily be able to alter the FreeBSD system.

C. Buechler & S. Ullrich worked on this PfSense project in 2004 & released the first project in 2006. The Packet filtering tool gives its name to the product. Netgate had been employing the domain to dishonor the OPNsense & also obliged Netgate in transferring the domain to Desico as a competing open firewall source. We have compiled some of the best hardware for PfSense in the article. We suggest you have a look at them.

Here are some of the feature considerations for PfSense, however this feature might not be affected with hardware but still hardware utilization is an important factor. Considering the VPN usage, we must consider that using a VPN will increase the CPU requirements. Hence the AES-NI acceleration here can decrease the CPU requirements significantly. Captive Portal users will also need more power of CPU. Another feature State Tables also affect the hardware (CPU) usage. Generally, 1 KB of RAM is needed for a single state table. For example, consider a RAM of 1 Gigabyte. A firewall of 1GB RAM will need a 100 MB of RAM available for all the state tables. So adequate RAM must be available for the proper working of all the state tables in a large environment comprising of thousands of connections.

We are providing some of the minimum requirements for the hardware needed for PfSense 2.x. however, these are just the minimum ones & not appropriate for all the environments & can slow down the whole system.

MinimumCPU- 500 MHz / RAM-512 MB
RecommendedCPU- 1GHz / RAM- 1GB
Full InstallationCD-ROM or USB / 1 GB hard drive

Network Card Selection is also an important hardware selection factor. Network cards (NICs) is of significant importance as it is vital for performance. The reason behind this is, that inexpensive NICs can drench your CPU & then cause difficulty in handling. Network cards on Intel chipsets are more effective & efficient in working when they are used in conjunction with PfSense.

Also, the CPU selection is an important factor as we have described the usage of CPU above in detail. We have gathered some information & presenting it to you. However, these stats can be increased or decreased slightly. For 10 to 20 Mbps the recommended modem is Intel or AMD clocked at 500MHz. while for 21 to 100 Mbps the recommended modem is 1.0 GHz Intel. And next is the category 101 to 500 Mbps & a modem of at least 2.0 GHz is needed. The final category is 500+ Mbps & multiple cores at 2.0+ GHz are necessary for this. Hence throughput must be considered well in order to secure your Wireless network with PfSense. Here is the list of the best hardware for PfSense.
