Blocked hosts for localhost do not blacklist ip in Kloxo MR

[lenawaii]

Hi,

I have done a test, I wanted to block one address IP from accessing my server. I identified a spammer on my website and I wanted to blacklist his IP, so I used the following option in Kloxo MR > admin > security > Blocked Hosts for localhost and I added my mobile IP address with 3G connexion not my Internet box IP and apparently i still can access :
- Kloxo MR panel
- All website in the panel

So blacklisting does not work, what's wrong? If you have the solution, i'll take it. If no solution, what do you suggest to secure my web server?

This is really important to fix this so that I protect my webserver from spammers.

Thank you guys for helping

Use firewall (like iptables) for IP blocked.
