It works and the attacker, on second and subsequent attacks, gets a 403 error response. I want to extend the exclusion ability to every web site hosted on a server. My preferred method is iptables. However, when

I am forwarding traffic on port 8080 to port 80 with following rule. # iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 8080 -j REDIRECT --to-port 80 # iptables-save However, I am unable to add it directly in /etc/sysconfig/iptables. I think it is used only for filter table and not nat table. So where do nat table rules go? Any help? - cs.
