Hi All,

I have tryed to install transparent proxy but I didnīt
understand the correct funcionality of the ipfw rules
to squid transparent proxy.

I installed transparent proxy like a tutorial that says
to include the follow rules in ipfw:

allow tcp from any to any
fwd 127.0.0.1,3128 tcp from any to any 80

Well, how ipfw read line by line, I think itīll leave the
server without firewall, once the first rule allow everything.

But, if I test the proxy, it really works, that is to say,
the tcp frame pass to the second rule (fwd).
How is this possible?
