Iptables -m limit problem

Hello netfilter list,
I want to limit connectionss to http port to maximum 2 persecond from one host. I wrote the following line but it's not working :(

/usr/local/sbin/iptables -A ip_limit -p tcp --dport 80 -m limit --limit 2/second -j ACCEPT /usr/local/sbin/iptables -A INPUT -j ip_limit

Best regards,
 ITM                          mailto:[email protected]
