I am pleased to announce that a release of Qubes Mirage Firewall is just out (0.8.3) which should solve some of the recent annoying problems: Release autumn 2022 bugfixes · mirage/qubes-mirage-firewall · GitHub
You will also find the reproducible builds at Robur soon: Job qubes-firewall
I really want to thank everyone for tracking bugs and fixing issues for this release!
If you have any comments, please let us know, on this forum or on github.
The next step is to propose the firewall for integration into the Qubes Community Repository!
