Hi sephe,

Thanks for the suggestion.  I don't use NAT, and I will try out the
IPFW, and will report back.

One reason for my choice of IPFW3 over IPFW, is that IPFW3 supports
*lookup table* which makes it easier to work well with Fail2ban.

On the other hand, I'm also planning to try PF, which I think also
supports the lookup table feature (??).
