It wold be fine to have a ipdivert.ko that could be loaded on demand of
ipfw.ko or via /etc/rc.d/natd. I think the main reason why we have no
ipdivert.ko around is that the ipdivert code toches severeal kernel sources.
As I understand it, the divert proto is not just a piece of code that could
simply pluged in and out (for now).
I have no problem with logging diabled by default, as enabling needs only one
line in rc.conf.
ps: please dont top-post and use some indentation character for quoting of old
message text. This makes reading much easier.
