How to install Fail2Ban

Hello, I wish to install Fail2Ban because I need to access the phone server also from a remote extension, but I don’t see in the Admin Module any module to be installed. From which location I install it?
I have build 2.11.0.23
Thanks

You can access to this on Admin–> System Admin.
But you should register your server for free or commercial version.

(You can check Fail2ban installation with SSH to your server too )

thanks, I’d some problems so I decided to unistall firewall and ‘‘bind’’ port forwarding only for ports coming from a certain specific IP address.
