Firewall frequently unresponsive, cannot update etc

[aerospyke]

Hi all, I have a Protectli (4core i3, 16GB DDR4) device running opnsense (200GB UFS) with zenarmour, an ipsec vpn, DHCP for an isolated VLAN. I dabbled with IDS rules but not much (and have not yet moved to IPS).

Anyway, enough background, I had a problem with my firewall so I tried to start peeling back layers to see where the problem lay. So I uninstalled all sensei components, disabled IPS but didn't fix my problem, but trying to put them back, the firewall went unresponsive when reinstalling zenarmour and so now it is stuck. It shows unconfigured in the UI, despite it being installed through the UI, and it doesn't show up. Trying to remove it causes the firewall to instantly reboot. There's an update for the opnsense firmware as well but when that tries to update, the firewall instantly reboots. Overnight frequently the firewall goes offline and I have to hard reset it to get it back online.

Checking temps look fine, memtest ran for 2 hours without error but do not know where to go next. Any help what I can try to find what is up? I don't even know if it is software or hardware anymore.

It's easier to start with a working config and adding things, rather than a broken setup and fix randomly.

Do a fresh install and add features until you hit issues.

Thanks, i'll have to reinstall tonight then. If I export a configuration or perform a backup, is that more likely to bring back the issue? Am I more recommended to just take screenshots of what i've done and recreate it all from scratch?

It never hurts to take a backup. I would boot the firewall from Clonezilla and image the drive that gives you a roll-back even if it is badly broken. https://clonezilla.org/

Also back up the config to compare against the fresh clean one and/or copy bits such as certs and keys.
