Hi there.
We have had this problem for a long time where our OPNsense firewalls reset anytime they are rebooted. This makes it kinda useless since we can't have that anytime it loses power or anything we need to set it up again. Anyone else having this problem and if so know a fix? Is this some config setting we have turned on by mistake?
Maybe you left the installation media in the device and boot from that every time?
That would not seem to be the case no
"firewalls" implies this happens on more than one install? Did you install at all? Or just boot the live-system?
