I like Fail2Ban, but as I remember it, my learning process looked a lot like this:

1.) Read through the documentation.

2.) Pour myself a scotch.

3.) Read through more documentation.

4.) Start drinking right out of the bottle.

5.) Try something.

6.) Get an error or experience a spectacular failure.

7.) Use StackOverflow.

8.) GOTO 5.

-------------

In good news, it worked - the light went on and now I'm confident that I could adapt Fail2Ban to suit any use. But, in bad news, honestly, I feel your pain and understand where/why you are getting stuck. Fail2Ban is a very complicated, yet extremely useful piece of software.
