So I just learned that there's two methods to doing NAT in FreeBSD. The apparently old natd + divert way, which is documented in the handbook, and the new in-kernel ipfw+nat way, that is randomly documented by Google. Is anyone ever going to update the handbook to over ipfw+NAT? The man page...

I want to mount a firewall. I have the idea of that my traffic could be "sniffered" by somebody. So I will ask for how to mount a firewall, here, on my desktop installation but also on another equipment. Besides, I want to know what else can I do for making the most miserable the attack of a...
