Hey people,

I've seen some efforts from the netfilter community on Linux to provide a
means to limit brute-force attacks via firewall rules. Can anyone suggest a
way to do the same on FreeBSD? 

I'm primarily interested in limiting attacks on sshd. I already use RSA auth,
but I like defense-in-depth.
