I have some good ideas to work with.
I guess my main problem is that both the firewall machines are POWERED from the server box, so I cant really poll the server because if the server is shutdown, then the power will be turned off at the end of the shutdown (bringing both the firewall boxes down with it with a crash!) - Maybe I need to disable the power off feature on the server box.
