*You* actually means: You have to have don it yourself, on the
machine you want to use it before anyone is putting it to serious
tasks. Been there, watched it being done, got a cellar full of t-
shirts...

That was not my attempt at being funny ("Oh - yes, I needed that
connection on the KVM switch. Didn't I tell you?").

I prefer doing the reboot thing from time to time, having had quite a
history of customers neither testing nor documenting changes in
system configuration... It's reducing the number of surprises per
boot considerably.

Windows' "firewall" couldn't keep me outside either... The problem
isn't FreeBSD, it's the idiots in front of it fumbling around with
the pitchfork.

As I said: It's not about changing the rules, it's about loading
kernel modules that could aid you in serious in-the-knee-shooting.
