web content filtering with 6.0

[Dave]

Hello,
    I've got a 6.0 box running squid as a transparent proxy. I want to 
implement web content filtering, popup blocking, add blocking, porn site 
blocking and selective filtering etc. I've read some howtos on a package 
called dansguardian and another squidguard and adzap that linked in to squid 
to provide some of this functionality. The stuff i saw was for freebsd 4, 
nothing for 5 or 6. If anyone has web content filtering using these or other 
packages going under fbsd6 i'd like to know how you did it.
Thanks.
Dave.
