Any other pertinent information you left out that you would care to
share????

I'll assume you are running Linux on the server you are trying to protect
and suggest hosts.allow and hosts.deny. You could also use iptables and fix

But then I'm only guessing what you have available and what you have tried
and I'm not a fucking mind reader.
