install iptables

help me,

install iptables on CentOS6.2 ( step by step )

thanks,

 

iptables is installed by default
use iptables --help or man iptables for usage help

 

Or if you struggle with creating the rules you might have a look at several building tools like firehol (http://firehol.sf.net), fwbuilder etc, to just build you more generic ruleset and let them generate the iptables commands for you.
