Keyword Blocking
The NBG4615 can block Web sites with URLs that contain certain keywords in
the domain name or IP address. For example, if the keyword "bad" was
enabled, all sites containing this keyword in the domain name or IP address will
be blocked, e.g., URL http://www.website.com/bad.html would be blocked.
