I tried for a few months to figure out a way to run Squidguard and 
transparent proxy only using the K12LTSP box.  It didn't work at all.  
So I finally had to put in another box to do the proxy'ing.  Worked 
great!  grab an old box, throw command line on and you're off to the races.
Adam's how too is extremely helpful!
