How about using ipfw to prevent outbound HTTP connections to the
offending addresses?

I'm somewhat new at this DNS stuff but is it possible to somehow use
my
local copy of bind to make unwanted URL's disappear?  Unwanted URL's
meaning
known Ad Servers and by disappear I mean lookups resolve locally to
127.0.0.1 or 0.0.0.0 ... kinda' like RBL but for browsers.

I tried using my hosts file for this purpose but it didn't seem to
totally
make the "advert" problem go away.  I don't know why.

I'm running FreeBSD 4.3 and bind 8.2.3.  The system uses ipfw and
natd to
provide a gateway for all my internal systems (192.168) to connect to
the
internet.  It seems like such a logical place to discriminate against
unwanted URL's...

Thanks
