Why does it have to be CentOS? If you want a wonderful router/firewall 
that you can have up and running in a few minutes, you should look at this:


I quote from their website:

"pfSense is a free, open source customized distribution of FreeBSD 
<http://www.freebsd.org> tailored for use as a firewall and router. In 
addition to being a powerful, flexible firewalling and routing platform, 
it includes a long list of related features and a package system 
allowing further expandability without adding bloat and potential 
security vulnerabilities to the base distribution."

If you insist in using Linux instead, you could look at this:


Once again, a distro specialized on the function it performs.

Why have a generic and bloated system that you then have to customize 
from scratch when such wonderful specialized projects already exist?

I use Linux servers and a pfsense firewall to protect the network. Works 
like a charm, with amazing stability and reliability.
