Hardware Architectures
pfSense is supported only on the x86 architecture. The types of devices supported range from standard PCs to a variety of embedded devices. It is targeted at x86-based PCs 300 MHz or faster.
Minimum Hardware Requirements
We suggest at least a Pentium II processor with at least 128 MB RAM. You may be able to get by with less than that, but with less memory you may start swapping to disk, which will dramatically slow down your system.
Recommended System BIOS Changes
There are some BIOS settings that may need to be changed for pfSense to function properly.
Plug and Play OS
Most system BIOS have a setting for "Plug and Play OS" or something similar. This should always be set to "no" or "disable". With this setting turned off, the BIOS assigns system resources rather than leaving that up to the OS. FreeBSD (and hence pfsense) works best when the BIOS handles this task.
Disabling Unnecessary Devices
You most likely won't have to worry about this, but if you have hardware-related issues, we recommend disabling all unnecessary devices in the BIOS, such as onboard sound, and in some cases parallel ports, serial ports, and other unused devices. If you aren't using it, it is safe to disable it.
Hardware Sizing
Determining the exact hardware sizing for your pfSense deployment can be difficult at best, because network environments differ dramatically. The following will provide some base guidelines on choosing what hardware is sufficient for your installation. Stated throughput numbers are very conservative for most environments, leaving some room for error and future expandability.
Network Card Selection
We will address this first, because your selection of network cards (NICs) is the single most important performance factor in your setup. Cheap NICs will keep your CPU very busy with interrupt handling, causing your CPU to be the bottleneck in your configuration. A quality NIC can increase your maximum throughput as much as two to three fold, if not more.
FreeBSD refers to network cards by their driver name followed by the interface number. For example, if you have two Intel Pro/100 cards (fxp driver) and one 3Com 3C905 card (xl driver), you will have interfaces fxp0, fxp1, and xl0 respectively. Intel Pro/100 and Pro/1000 cards tend to be the best performing and most reliable on pfsense. Cheap cards like those containing Realtek chipsets (FreeBSD rl driver) are very poor performers in comparison.
If you are purchasing NICs for your pfsense installation, we strongly recommend purchasing Intel cards. You can find them on ebay for less than $30 USD for 3-5 cards in a bulk lot. For low throughput environments, like any typical broadband connection 6 Mbps or less, any NIC will suffice unless you are seriously lacking CPU. If you require fast throughput (more than 30-40 Mbps) between interfaces for multiple LAN networks, or between a DMZ and your LAN, then using quality NIC's becomes much more important.
The numbers stated in the following sections can be increased slightly for quality NICs, and decreased (possibly substantially) with low quality NICs. All of the following numbers also assume no packages are installed. Some packages can increase the system requirements, and some can increase them substantially.
6-8Mbps (Residential / SOHO)
With the typical residential or small office broadband connection of up to 6-8 Mbps, a 200 MHz system with 128 MB RAM will suffice. Remember if you want to use your pfSense installation to protect your wireless network, or segment multiple LAN segments, throughput between interfaces must be taken into account.
20-50 Mb Throughput
To achieve 20-50 Mb throughput, you generally need a system between 400-600 MHz.
100 Mb Wire Speed
In order to achieve 100 Mb wire speed throughput, you typically need a system between 700 MHz and 1 GHz.
High Throughput Environments
In environments where extremely high throughput through several interfaces is required, especially with gigabit interfaces, PCI bus speed must be taken into account. When using multiple interfaces in the same system, the bandwidth of the PCI bus can easily become a bottleneck. Most typical motherboards only have one or two PCI buses, and each can run an absolute maximum of 133 MBps, or 1064 Mbps. That's less than one gigabit interface can transfer. PCI-X can transfer up to 1056 MBps, or about 8.25 Gbps.
If you need sustained gigabit throughput at wire speed, you will want a server-class motherboard with PCI-X slots and PCI-X NIC's. You'll also need a 2.8+ GHz CPU.
