Site and Server security

I am running CSF firewall on my server and wish to block IP addresses of entire country like China, Korea etc.

Is it possible to do from CSF?

Yes, new CSF version has a facility to block entire country.

1. Login to WHM.
2. Go to Configserver security firewall.
3. Click on Configuration option.
4. Enter codes of countries you wish to block in "Country Code to CIDR allow/deny" option.

Thanks!
