It is available through Fedora Extras ( 3 + 4). A bit biased, as I am maintaining the package ;) For application independent blocking I feel psad is worth a close look: http://www.cipherdyne.com/psad/. I used it in past. If you know "portsentry", psad is the better alternative (see the comparison of those 2 on the psad page).
