We finally upgraded from BM 3.7 to 3.8. We only use it for blocking out
specific URL's and tracking student web access, so there is no filtering
done, just a handful of access rules. Our access rules have a Deny certain
URLs at top, and allow any ports second, and that's it. (We have another
box performing firewall duties).

Now students cannot get to some web pages that do searches (some they can,
e.g. google is OK) - haven't figured out what is different. They get
standard 403 forbidden page (not the BM error page). Teachers can get out,
so its something to do with BM as their proxy, but not the BM rules.

What else is there?
