How to use transparent kernel proxy with squid?

[eculp at encontacto.net]

I want to use squid as a transparent proxy for http.  The last time I did
this several years ago I used transproxy but I understand that it can
now be done in the kernel.  I have all the firewall options compiled in the
kernel [current] and ipfw and natd are working as expected.  I am trying to
do something like

ipfw add 300 fwd 127.0.0.1,3128 tcp from 192.168.1.0/24 to 0.0.0.0/0 80  \
recv rl1 out xmit rl0

Squid and the firewall are running on the same machine and and I want all
the 192.168.1 network to be forced to use squid.

Thanks for any tips,

ed
