Web content filtering in Ubuntu??
I need to set up a web filter for my Ubuntu Jaunty and (possibly) my Windows XP machine. I definitely don't mind (Heck, I want) a hardware based filter, as in I connect to the internet through another PC that acts as a modem. I found instructions here (geek.com/articles/chips/feature-buiding-a-mini-itx-web-content-filter-with-ubuntu-20090116/) but I don't want it to affect the other 3 computers in my house.... Ideas?
EDIT: I already have a small PC laying around that I could use, so purchasing hardware is not an issue.
