Good Information about ipfw

Tue Jun 1 12:59:40 PDT 2004

Is there a good, definitive, source of information for implementing ipfw firewall rules. I am familiar with the man pages, howerver, a list of arbitrary functionality, without any clue as to how to actually empliment them is of no use to me.
I am in Mozul, Iraq, and I have limited time on the Internet, and far less resources than I did before I got activated to come over here. 
I would also like to know what the point of most man pages are.  90 percent of them just list arbitrary commands, as though you are supposed
to know how to use the program in the first place.  There are almost never any useful information about implementing the program that the manpage is supposed to explain, but does not. 

I have not been able to locate any book on the one firewall, that seems
to be at the heart of any good Freebsd firewall setup. 

Please help this wayward soul.

Thanks fellow BSDers.
