Are you wanting to keep it from dialling on demand for certain ports?  Is
that the idea?  In this case you need to define a dfilter in your ppp.conf
file... (not ipfw).

What I'm trying to do is to is to find a rule that will enable me to block access to the outside world on certain ports whilst the FreeBSD box is not connected via ppp, but then allow access to them when the box is connected. Any suggestions?
