Content Filtering
12.1 Overview
Content filtering gives you the ability to block web sites that contain key words (that you
specify) in the URL. You can set a schedule for when the ZyXEL Device performs content
filtering. You can also specify trusted IP addresses on the LAN for which the ZyXEL Device
will not perform content filtering.
12.1.1 What You Can Do in the Content Filtering Screens
• Use the main Content Filter screen ( Section 12.2 on page 131 ) to enter the Keyword ,
Schedule or Trusted screens.
• Use the Keyword screen ( Section 12.3 on page 132 ) to block sites containing certain
keywords in the URL.
• Use the Schedule screen ( Section 12.4 on page 133 ) to set the days and times for the
ZyXEL Device to perform content filtering.
• Use the Trusted screen ( Section 12.5 on page 134 ) to exclude a range of users on the LAN
from content filtering on your ZyXEL Device
12.1.2 What You Need to Know About Content Filtering
URL
The URL (Uniform Resource Locator) identifies and helps locates resources on a network. On
the Internet the URL is the web address that you type in the address bar of your Internet
browser, for example “http://www.zyxel.com”. An IP address can also be a URL.
12.1.3 Before You Begin
To use the Trusted screen, you need the IP addresses of devices on your network. See Section
12.5 on page 134 for more information.
