Due to the fantastic features of Qubes and OPNsense, there is a desire to run the latter as a VM under Qubes. You should know that OPNsense itself is a free firewall distribution based on FreeBSD (specifically HardenedBSD). Since I don’t have much experience with Qubes OS yet, I’d like to ask the community if there are any experiences on this aspect and I’m looking forward to your feedback.
Perhaps this might help:
A little bit, thanks
