Hello All,

In order Unblock IP address/es from CSF Firewall at command line one need to execute below mentioned commands:

1) Login into the server via shell access.
2) Go to the path of APF firewall. It should be:
/etc/csf
3) Edit the file csf.deny.
vi csf.deny
4) Remove the IP address from the list and save the file to unblock the IP address.

Once the IP address removed one need to restart the Firewall…To Restart Firewall one need to execute below mentioned command:

csf -r

That’s it!

Thanks,
