Content Filtering
This chapter provides a brief overview of content filtering using the Web Configurator. For more detailed
information, consult the HTML help section of the included disk.
Internet content filtering allows schools and businesses to create and enforce Internet access policies tailored
to their needs. Content filtering gives 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, Click on Main Menu,
then Content Filter to expand the content filter menus.
20.1 Categories
20.1.1 Restrict Web Features
The ZyWALL can block web features such as ActiveX controls, Java applets, cookies as well as disable
web proxies.
20.1.2 Filter List
The administrator can block categories, such as pornography or racial intolerance, or monitor visitation
from a pre-defined list. Upon registration of the ZyWALL, the use of the list is free for a trial period.
After this period, you must subscribe to the list periodically.
20.1.3 Days and Times
The ZyWALL also allows the administrator to define time periods and days during which content
filtering is enabled.
