It's not really clear what you are asking. Are you just looking for
general documentation?
http://netfilter.org/
CentOS-specific docs?
https://access.redhat.com/site/documentation//en-US/Red_Hat_Enterprise_Linux/6/html/Security_Guide/sect-Security_Guide-Firewalls.html
Something more specific? If so, please give real details so people can
give you real help.
