Chris, you still didn't answer *why* you have to reboot them. What exactly is the symptom that makes you think you have to reboot?
I assume now that with "My firewall says it's blocked" you referred to the drops? (Next time say so, as this wording is really ambiguous.)
What would you like to know about my situation? I have 6 servers running
Yeah, so you are not a home user where one could rate-limit the port ;-)
