If your using ports 0-3 try moving over to ports 4-7 until you get your replacement. Once the ports start going they tend to run in pairs…
Thanks for the heads-up on the NIC ports.
I remember reading in the excellent "Firebox" section of the forums that the right side ports (msk0 thru msk3) were suspicious, and based on the comments I've avoided using those. So I'm reluctant to make any change pending the replacement firewall(s.)
Still, wondering about the root cause. I was under some duress, and didn't copy the logs before rebooting. A quick glance at the dashboard gave the false impression all was okay. Seems like the auto-reboot script similar to https://forum.pfsense.org/index.php/topic,17243.0.html could have brought the box up without my intervention. Seems there's mixed thought on reboot scripts, but I've now added a variation that might come in handy, if called upon.
Thanks everyone…
