How to Block Countries Using CSF Firewall

To block countries using CSF's firewall, you can use the "CC_DENY" directive in the CSF configuration to add a country's code:

Log in to WHM
Select "Plugins"
Click "ConfigServer Security & Firewall"
Select the "csf" tab
Click "Firewall Configuration"
Scroll down to the Country Code Lists and Settings section
Enter the country codes in the "CC_DENY" field, using two-letter ISO 3166-1 alpha-2 codes. For example, "US" for the United States, "GB" for Great Britain, and "DE" for Germany.
To block multiple countries, separate the codes with commas and leave no spaces. For example, "US,GB,DE" to block the US, Great Britain, and Germany.
