How To Use the IP Blocker in cPanel
As a matter of following security best practices, you should protect your server with a firewall. Fedora 23 and CentOS 7 come with firewalld, an alternative to iptables.
For security best practices, do not disable firewalld without enabling another firewall solution. Disabling firewalld without enabling an alternative will leave every port on your server open and completely unprotected.
Liquid Web has introduced a new feature designed to simplify the removal of errant IP address blocks in the firewall, and allow customers to quickly remove their own address from within their Manage dashboard. In this manner, customers can remove blocks on their IP addresses even when they are unable to access WebHost Manager itself due to the block.
Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are common threats that every publicly accessible web server faces. The purpose of such attacks, in the simplest terms, is to flood a server with connections, overloading it and preventing from accepting legitimate traffic.
In addition to being able to manage traffic from a specific country or a list of countries, CSF allows you to manage access by country to specific ports. This can be useful if you need to ensure that a particular service is available globally (such as your web server on port 80) but want to restrict international access to services such as WHM/cPanel, SSH, or FTP.
One of the most-requested features on cPanel servers is the ability to manage and filter traffic at a country level. With the ConfigServer Firewall (CSF) plugin in WebHost Manager, you can do exactly that.

Prior to making direct edits to the firewall configuration file or changing advanced firewall settings in WHM, a backup of the current configuration should be taken so that the settings can quickly and easily be reverted if needed.
Should you discover (or suspect) that a client or customer’s IP address has been blocked by the firewall on your cPanel VPS server, or should you just need to open or close a port, you may be able to quickly resolve the issue yourself with just a little help.
