CSF - Thoughts?

I’m just looking into a few ways I can increase security on my server a tad.
One I’ve seen people mention is ConfigServer Firewall and I see in updates notes that it now has a tie into Webmin.

Anyone using this and have thoughts on it?

I’ve been using CSF for about a year now. Rather handy firewall script. Has MANY other features.

Issues:
I have noticed that it has a tendency to block legitimate users via temp blocks on Apache (based on my settings) and also fails to block password guessing on Dovecot (I’m using Centos 5.4).

Certainly worth a try. It’s very configurable and all the settings are well documented.
