pfSense 2.7.0 dashboard

pfSense is a firewall/router computer software distribution based on FreeBSD. The open source pfSense Community Edition (CE) and pfSense Plus is installed on a physical computer or a virtual machine to make a dedicated firewall/router for a network.[4] It can be configured and upgraded through a web-based interface, and requires no knowledge of the underlying FreeBSD system to manage.[5][6]


The pfSense project began in 2004 as a fork of the m0n0wall project by Chris Buechler and Scott Ullrich. Its first release was in October 2006.[7] The name derives from the fact that the software uses the packet-filtering tool, PF.[8]

Notable functions of pfSense include traffic shaping, VPNs using IPsec or PPTP, captive portal, stateful firewall, network address translation, 802.1q support for VLANs, and dynamic DNS.[9] pfSense can be installed on hardware with an x86-64 processor architecture. It can also be installed on embedded hardware using Compact Flash or SD cards, or as a virtual machine.[10]

WireGuard protocol support

In February 2021, pfSense CE 2.5.0 and pfSense Plus 21.02 added support for a kernel WireGuard implementation. Support for WireGuard was temporarily removed in March 2021 after implementation issues were discovered by WireGuard founder Jason Donenfeld.[11][12][13] The July 2021 release of pfSense CE 2.5.2 version re-included WireGuard.[14]
