Newbie inquiry regarding Mod_Security and Comodo WAF.

Hello,

I have installed Mod_Security from this article. It is because when I was using the built-in installer from CentOS WebPanel, some functions of my WordPress websites does not work even if I have done rebuilding Apache and rebuilding the vHost again. Now, I was able to install both Mod_Security and Comodo WAF. My question is, do I have to turn on the built-in firewall protection of CentOS WebPanel aside from the protections offered by Mod_Security and Comodo WAF?

Thanks.
