Het pakket OPNsense is een firewall met uitgebreide mogelijkheden. Het is gebaseerd op het besturingssysteem FreeBSD en is oorspronkelijk een fork van m0n0wall en pfSense. Het pakket kan volledig via een webinterface worden ingesteld en heeft onder andere ondersteuning voor 2fa, openvpn, ipsec, carp en captive portal. Daarnaast kan het packetfiltering toepassen en beschikt het over een traffic shaper. De ontwikkelaars hebben OPNsense 20.7.6 uitgebracht met de volgende aankondiging:
OPNsense 20.7.6 releasedThis update brings the usual mix of reliability fixes, plugin and third party software updates: FreeBSD, HardenedBSD, PHP, OpenSSH, StrongSwan, Suricata and Syslog-ng amongst others. Please note that Let's Encrypt users need to reissue their certificates manually after upgrading to this version to fix the embedded certificate chain issue with the current signing CA switch going on. The mail backup plugin is currently not available pending a response from the maintainer. Users are advised to avoid using it for the moment.
