What’s pfSense?

First things first, pfSense is an open-source firewall and router computer software. If you want your own firewall and route, this can be installed on a machine or a computer. The great thing about this upgrade is that you can configure it without a hassle and moreover, you can easily alter the FreeBSD system.

In this review, we will guide you through the different features these devices offer. Netgate, OPENsense, and Desico are all competing for for open firewall sources, but pfSense is the most reliable commercial firewall software. But since it needs hardware to work and there are many options on the market, we have grouped the very best hardware for you.

Why pfSense and Not Commercial Routers?

Even though pfSense is, as we mentioned above, open-sourced, this might be considered a concern due to the fact that is community-based, However, there are many advantages that pfSense has over standard routers and firewalls.

First of all, pfSense is reliable, unlike the common mass-produced routers. These off-the-shelf routers have a limited utility due to manufacturer lock-down; plus software vulnerabilities. You see, fabricators of common routers don’t have many reasons to patch software bugs, performance problems, or even serious security holes.  

On the other hand, pfSense is frequently updated and quickly takes care of any security issues. For this reason, pfSense’s potential issue becomes its strongest link. With this software, you are in control of your networks with reports that you have access to. It also has a tool called ‘p0f’ and this tool allows you to observe what type of OS has tried or is trying to connect to your router. And most importantly, pfSense records all of your traffic. There are packages you can install to sort out bad traffic, making it an excellent firewall.

Features

Since using a VPN will increase the CPU requirements, the AES-NI acceleration can decrease the CPU significantly. In addition, Captive Portal users also need more power of CPU. Moreover, State Tables affect the hardware (CPU) usage as well.

Generally, 1 KB of RAM is needed for a single state table. So let’s consider this example: a firewall of 1GB RAM needs 100MB of RAM for all the state tables. For this reason, you need suitable hardware with sufficient RAM available to ensure proper performance of state tables in a large environment that comprises thousands of connections.

GENERAL REQUIREMENTS
Minimum CPU- 500 MHz / RAM-512 MB
Recommended CPU- 1GHz / RAM- 1GB
SPECIFIC REQUIREMENTS
Full Installation CD-ROM or USB / 1 GB hard drive

First, when it comes to selecting a hardware, Network Card Selection is an important factor. since Network cards (NICs) are vital for performance. Consequently, inexpensive NICs can drench your CPU and then, cause difficulty in handling. Network cards on Intel chipsets are more effective and efficient in working when they are used in conjunction with PfSense.

The CPU selection is an important factor as we have described the usage of the CPU above. According to the information we’ve gathered, these stats can be increased or decreased slightly. First, for 10 to 20 Mbps the recommended modem is Intel or AMD clocked at 500 MHz. On the other hand, for 21 to 100 Mbps the recommended modem is 1.0 GHz Intel. Next, for 101 to 500 Mbps & a modem of at least 2.0 GHz is needed. And lastly, for 500+ Mbps and multiple cores at 2.0+ GHz are fundamental. Hence, high throughput secures a Wireless network with PfSense.

Let’s dive into the best hardware for PfSense:

Also, it includes 3x USB 2.0, 1x USB 3.0 ports. As you know, it’s always good to have many USB port options. Not to mention that there is an mSATA SSD slot & DIMM slot. And its memory slot has the following: Support 1333/1600MHz, 1.35V, Non-ECC, and DDR3 SO-DIMM Memory. But there’s no hard drive and RAM installed. It’s must be no surprise to know that you have to install these by yourself.

Although it has predefined holes in it for the WiFi antennas, you’ll have to install it as well. You can run it on any available operating system like Windows 7, 8, and 10. But it has no pre-installed operating system on it. Don’t fret! This is a good opportunity for you to buy it and customize the storage, memory, and operating system according to your needs. It can be used with firewall software but pfSense v2.5 requires AES-NI which Q190G4 doesn’t support. Therefore, keep in mind that v2.5 and future versions of pfSense are not supported.
