transparent squid and ipfw

[Fazal Ahmed Malik]

Dear All,
 
I have problem in setting up transparent squid and ipfw dummynet together on freebsd. I sent this question earlier but yet no luck to implement. I am using mpd5 for pppoe server and have addclient script which limit the user bandwidth(working perfect) now i want my all traffic redirected to squid transparently mean users does not need to configure their browser for proxy. When i redirect port 80 traffic to squid than bandwidth does not get controlled mean dummy net pipe is no more effective.
I have following ipfw rules and also addclient script is attached any body having implemented such solution please help.
