I’ve been playing with a FreeBSD machine for a while now and my primary server now runs FreeBSD 😀
So I came across this problem: installing Fail2Ban with IPFW.
FreeBSD has three different firewalls, so it’s difficult for any upstream application to decide on what kind of setup it should advocate. There is no one-size-fits-for-all. I read about various firewalls, and since I wanted to stick with FreeBSD only, I decided to use IPFW.
