This makes me want to cry! WebGUI instability on all different hardware!

[roohoo]

I don't believe it!  I decided that I'd try reinstalling OPNsense as a VM under Proxmox so that Proxmox acted like a sort of Hardware Abstraction Layer.  I even boosted the RAM to 64GB so that OPNSense could have 16GB.

The result:  Exactly the same.  The firewall appears to keep working, with all my network's devices keeping their Internet connectivity, but the webgui is displaying nonsense - with the characteristic 20000+ days uptime (the correct uptime, as displayed in the shell, being 1 hour 45 minutes).

I'm so disappointed as I thought that this might cure my issues - with Linux drivers handing virtual hardware to OPNsense, but it wasn't to be!

That completely rules out the issue with opnsense. Your clients are broken, or something between your clients and opnsense.

The keyword is "webgui" here... as it seems, not even the time being off is present when using SSH.

When the problem occurs only on the web gui, it has to be the client, which means browser or some kind of plugin. I would try another browser first.

But...

I'm setting it running and then leaving it alone.  Nothing configured except for the interfaces and ssh access.  Every now and again I log in to see what it's up to.  I log into it from a myriad of different machines running lots of different browsers but the results are always the same.

Should not be the issue then I guess ?!

Could still be a plugin or an antivirus engine.

Please:

root@opn-dev-02:~ # sysctl kern.boottime

Also, after booting:

sysctl kern.msgbuf

[roohoo]

I installed Sophos firewall to see how it fared.  For the first 15 hours, it worked perfectly, then all internet access stopped.  It had dropped the connection to my (Gigaclear) fibre modem.  Rebooting the VM had no effect.  Only physically turning off the machine and turning it back on worked.

I'm starting to think that my wildly unlikely hypotheses that something on my network - or Gigaclear's - is sending malformed packets that can kill a router might actually be the case.

I was going to try pfsense too, but I've lost my enthusiasm.

Sorry I didn't get to try your troubleshooting ideas but constantly changing my router got really old really fast and my wife and others grew most perturbed every time their connectivity was interrupted!

Thank you again.

If I decide to investigate the benefits of OPNsense again in the future, and the troubles remain the same, I'll report in on this thread.

Thank you all.
