Download pfSense 2.5.2

Version 2.5.2 of pfSense has been released. This package is based on the FreeBSD operating system and focuses on router and firewall tasks. It is available in the free Community Edition and a Plus trim, previously offered as a Factory Edition. It started in 2004 as a fork of m0n0wall due to differing views among the developers and over the years has grown into a router and firewall package that can be deployed in both small and very large environments. For more information, please refer to this page. WireGuard was removed from version 2.5.1 as a precaution, but it returns in 2.5.2, albeit as an experimental option. The changelog for this release looks like this:
