[CentOS] iptables

Hi All,

I am running iptables on centos 4.5 and 5 boxes.

Now , I have requirements to enable below features.

Gateway level antivirus, anti spyware and intrusion preventions,
content filtering, etc.

I googled a bit. But, Still no luck to find proper Docs to enable these.

Can Iptables meet these features? If possible, Pls let me know some
documentations that say How to set up these.

Hope to hear from you.
