Installing and Configuring CSF Firewall

This article demonstrates how to install and configure the CSF (configserver) firewall. CSF can be used on a wide range of Linux systems, including those running cPanel.

rm -fv csf.tgz
wget http://www.configserver.com/free/csf.tgz
tar zxf csf.tgz
cd csf
sh install.sh
If you have APF + BFD you will need to disable it, you can use the following to do so:

sh disable_apf_bfd.sh
To configure CSF modify the config files in /etc/csf/ - or if you are running WHM you can modify the CSF settings in there. By default CSF opens the standard cPanel ports.
