I should've mentioned that I have the BIOS set to a graceful shutdown once the power button is pressed. I would never just push and hold the power button for a hard power down unless something was really wrong. pfSense has been pretty rock solid in staying up all the time.
Thank you for providing the link to the script. I'll be the first to say that I'm not a coder/programmer, but looking at the code in the script, I'm wondering if the ALLDEST is necessary? I guess by pinging whatever is chosen for ALLDEST you could tell whether or not any data was able to get in or out. I like the idea of checking the WAN to see if any data is able to pass, and if not, restart.
