ZyXEL 2WG 用户指南

ZyWALL 2WG User’s Guide

Content filtering allows you to block certain web features, such as Cookies, and/or block 
access to specific websites. With content filtering, you can do the following: 

• Restrict Web Features: The ZyWALL can block web features such as ActiveX controls, 

Java applets, cookies and disable web proxies.

• Create a Filter List: You can select categories, such as pornography or racial intolerance, 

to block from a pre-defined list. 

• Customize Web Site Access: You can specify URLs to which the ZyWALL blocks access. 

You can alternatively block access to all URLs except ones that you specify. You can also 
have the ZyWALL block access to URLs that contain key words that you specify.

• Use the General screen (

) to enable content filtering and 

configure external database settings. 

• Use the Policy screen (

) to configure content filtering policies on 

your ZyWALL.

• Use the Object screen (

) to configure lists of allowed and 

restricted web sites, and to block web sites based on keywords 

• Use the Cache screen (

) to view and configure caching of URLs 

and their categorization.

When you register for and enable external database content filtering, your ZyWALL accesses 
an external database that has millions of web sites categorized based on content. You can have 
the ZyWALL block, block and/or log access to web sites based on these categories. The 
content filtering lookup process is described below.
