Hi Cycle,
After thinking about this issue and checking the log files from our poor
server, I think
blocking ip addresses on the firewall is not a good idea, it wrong and useless.
I have to investigate further on and i will checkout black ice of course.

Sounds good, but i really won't get into Linux right now and and my budget for
additional
hardware is below zero ;-)
Thanks again.
