Opnsense is a free firewall - distribution based on FreeBSD and Address Space Layout Randomization (ASLR) of HardenedBSD. OPNsense allows the use of the free crypto library LibreSSL , as an alternative to the standard OpenSSL (selectable in the GUI ).

The OPNsense software is under the FreeBSD license ( "2-clause BSD license" ) and may be freely copied, changed and distributed, even for commercial projects.

Basic properties

The distribution can be downloaded for free.

Opnsense can on hard drives and CompactFlash cards installed , as well as Live CDs are started. OPNsense runs on a number of embedded systems , ordinary personal computers and as a virtual machine .

Typical applications are stateful perimeter firewalls, routers , wireless access points , DHCP servers, DNS servers and VPN endpoints. For this purpose, OPNsense offers features that are often only offered by expensive commercial firewalls. With the help of a web interface (web interface) OPNsense can be easily configured and updates can be set up comfortably without having to have precise knowledge of the underlying FreeBSD operating system. In contrast to comparable open source firewall software such as IPFire and pfSense , OPNsense offers two-factor authentication .

OPNsense is based on FreeBSD . Since OPNsense version 19.1. HardenedBSD version 11.2 is used as the operating system . The OPNsense Project is designed for code quality, easy code development and free access to the build tools. It applies the Model View Controller paradigm.

Surname

The name is derived from the suffix of the name of its predecessor pfSense and open and stands for: Open source makes sense .

history

The project was launched on January 2, 2015. It is a fork from pfSense , which itself began in 2004 as a project split from m0n0wall . The project cites three reasons for its split:

  • Technical reasons - clear, structured code base that can be used and maintained by developers should arise
  • Community - an active, sustainable community of users and developers is sought
  • License - OPNsense is to be built on the proven 2-clause BSD license, which can be used flexibly in commercial and free environments

The OPNsense project is financially and competently supported by the Dutch "Deciso BV" . Deciso BV has been a sponsor and co-developer of other free, open source software projects for a long time, namely for pfSense, m0n0wall, Askozia and Zen Load Balancer .

In November 2017, an arbitration tribunal for the World Intellectual Property Organization found that Netgate , the originator of pfSense, had maliciously used the opnsense.com domain to discredit OPNsense and ordered Netgate to transfer the domain to Deciso. The Netgate party tried to invoke the fair use clause , claiming that the domain name was "used on a spoof website"; this was rejected on the grounds that freedom of expression does not cover domain name registration.
