IPTABLES: Limit IP Connections Per Second


I would like to discuss what options I have to block IP's who launch 100+ simultaneous requests to a single page within a minute and drive up my CPU load to 100+

Basically, I need someone to help me write some IPTABLES rules that can help me to block such requests and I need to figure out how to calculate the best settings (e.g. how many connections are ok, how many not).

If you have experiences with IPTABLES rules and know how to prevent such nasty DDOS attacks, please bid.



Keep in mind I am familiar with modevasive, ddosdeflate, CSF, limitipconn and many many other, so if you have knowledge in this field and suggest another solution that is ok, but definitely need some good IPTABLES rules.
