Content Filtering
This chapter provides a brief overview of content filtering using the web embedded configurator.
Internet content filtering allows schools and businesses to create and enforce Internet access policies tailored
to their needs. Content filtering is the ability to block certain web features or specific URLs and should not
be confused with packet filtering via SMT menu 21.1. To access these functions, from the Main Menu, click
Advanced, then Content Filter to expand the Content Filter menus.
