Hi,
Twice now since I installed opnsense on a protectli I've had it kill internet on me. I can't even ping the firewall inside IP. What I do to fix it is push the power button until it shuts down, then turn it on again and all is well.
I have a suspicion that it's sensei causing the problem but I can't be certain without examining logs. The reason I suspect it is because once I initiate the shutdown sequence internet comes back fairly quickly until the box shuts down, so its seems as if a service is shut down at the point it comes back.
Short of being prepared at that moment to console into the firewall I'm not sure what I can do to check what occurred around that time.
OPNsense 21.7.1-amd64
FreeBSD 12.1-RELEASE-p19-HBSD
OpenSSL 1.1.1k 25 Mar 2021
I read somewhere in the forum about someone who configured one network port with a different ip-range, to be able to access the box in a situation just like this.
Found it: https://forum.opnsense.org/index.php?topic=23222.0
I set one up with a simple pass rule just in case I lock myself out of the other LAN port.
Considered this but it would be nice to find it in a log somewhere. Might have to resort to this
