  Unfortunately, probably not.  RADIUS is about obtaining network
access, not about controlling users once they have network access.

  You might be able to send filter rules to the access points, which
do IP layer filtering.  e.g. blocking outbound port 80, or forcing it
to go through a proxy.  Even with that, you'll have to consult the NAS
documentation to see if it's possible, and how to do it.

  As for blocking web sites, you'll have to install a web proxy, and
do the blocking there.  RADIUS just isn't the solution to that
problem, but it can help.  Maybe.  You may be better off just adding
hard-coded rules with AP's that force outbound port 80 to go through a
web proxy.  You may not even need RADIUS at all.

  It didn't sell well.  But I'm in the process of writing a book,
which should be available before Christmas.
