comment ip tables, block all traffic to a specific ip, unless it comes from a specific ip
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --src 22.22.22.22/24 --sport 443 --dst 11.11.11.11 --dport 443 --jump ACCEPT [the problem is I need another rule to ban all other IPs trying to connect to that IP on port 443]

How is the raid set up? The stripe size can actually impact performance in situations like this.
