Install/Configure firewall on VPS CentOS Server

I have a VPS CentOS server hosted with just a very basic IPTABLE firewall. I need someone to set up a firewall on the server for me that allows report generation and automated blocking (too many tries logging in via SSH, port probing etc). I would like the firewall to be web based to allow me to easily make changes to it. I want the option to manually lock down the server via IP address or service port. I would also like to easily have the ability to open/close ports. You are free to use existing software under a license that requires no fee or limit to use.
