The ''filter'' option is the name of a file in ''config/filter.d'' without the ''.conf'' extension. The ''action'' field is more interesting. Here, we set as first action the ''iptables'' script. Action script can have parameters. Have a look at ''config/action.d/iptables.conf''. Please, be aware that '''no spaces are allowed''' in the parameters field. This will be fixed in the future. We define a second action. It will send a notification e-mail. Just replace the ''dest'' parameter with your e-mail address. Be aware that the ''mail'' script uses the mail command of the system. Ensure this command works on your box.
