I have a real challenge for those resourceful ones out there!

Have a BM 3.7 server, which requires uers authenticate via CLNTRUST.

Everything is working as intended - web sites are blocked by
Surfcontrol
(Adult Sexually Explicit) and games.

This BM solution is in use at our High School. Am filtering primarily

the students' access.

Today I am told by some sources in our HS that students are able to
get
to blocked sites by doing a Google search, then accessing sites whose

URL's are blocked in Surfcontrol, by entering the IP address of those

sites in their web browsers.

Anyone come across this?

I would like to block specific categories of sites, by URL or any
other
method of getting to them, in this case the IP address entered into
the
user's web browser.
