How to Remove all blocked IPs from CSF in WHM?

Many server administrators use ConfigServer Security & Firewall (CSF) as a robust tool to enhance their server's security. However, there may come a time when you need to remove all the blocked IPs from CSF within WHM (Web Host Manager). This could be due to various reasons, such as resolving error messages, troubleshooting issues with legitimate users, or just starting the process again with your security configurations.

Understanding CSF :

ConfigServer Firewall, or CSF, bolsters server security through a user-friendly interface, enabling administrators to control public access to services and permitting only sanctioned connections such as FTP, email, and web access. Authorize only approved connections like FTP, email, and web access.

CSF has a helpful tool called the "Login Failure Daemon" or LFD. It watches for too many failed login attempts, which often means someone is trying to break in. When it sees too many failures from one IP address, it temporarily stops that address from using the server.

This restriction disappears after a while, but you can also remove it manually using the ConfigServer tool in WHM. CSF also lets you choose which IP addresses are allowed or not, and it actively monitors IP addresses that could be causing issues in real-time using LFD.

Steps to Remove Blocked IPs Using WHM:

Step 1: Log in to your WHM control panel.

Step 2: In the search bar, type ConfigServer Security & Firewall or just CSF. and click on it.

Step 3: Find the Flush All Blocks option within the CSF interface, usually located in the Firewall Configuration section or a similar area.

Step 4: Click on Flush All Blocks to eliminate all the blocked IP addresses from your server's firewall.

Following these steps, you can flush all blocks in CSF, effectively removing all the blocked IP addresses from your server's firewall using WHM.

Removing all blocked IPs from CSF in WHM is a straightforward process that can be achieved through WHM. Following the steps, you can quickly remove the list of blocked IPs and ensure that your server is no longer blocking any incoming connections. By maintaining a secure but accessible server environment, you can provide a better experience for your users while keeping your server protected from malicious activity.
