Software update: OPNSense 21.7

The package OPNsense is a firewall with extensive possibilities. It is based on the FreeBSD operating system and is originally a fork of m0n0wall and pfSense. The package can be set up completely via a web interface and has support for 2fa, openvpn, ipsec, carp and captive portal, among others. In addition, it can apply packet filtering and has a traffic shaper. The developers have released OPNsense 21.7 with the following announcement:

OPNsense 21.7 released

For more than 6 and a half years, OPNsense is driving innovation through modularising and hardening the open source firewall, with simple and reliable firmware upgrades, multi-language support, fast adoption of upstream software updates as well as clear and stable 2-Clause BSD licensing.

21.7, nicknamed “Noble Nightingale”, is one of the largest iterations of code changes in our recent history. It will also be the last release on HardenedBSD 12.1. We are planning to start the work on FreeBSD 13 as soon as next week for the 22.1 series.

The installer was replaced to offer native ZFS installations and prevent glitches in virtual machines using UEFI. Firmware updates were partially redesigned and the UI layout consolidated between static and MVC pages. The live log now contains the actual rule ID to avoid mismatches after adjusting your ruleset and the firewall aliases now also support wildcard netmasks. For a complete list of changes see below.
