Content Filtering
11.1 Overview
Internet content filtering allows you to block web sites based on keywords in the
URL.
See Section 11.1.4 on page 212 for an example of setting up content filtering.
11.1.1 What You Can Do in the Content Filter Screens
• Use the Keyword screen ( Section 11.2 on page 214 ) to block web sites based
on a keyword in the URL.
• Use the Schedule screen ( Section 11.3 on page 215 ) to specify the days and
times keyword blocking is active.
• Use the Trusted screen ( Section 11.4 on page 216 ) to exclude computers and
other devices on your LAN from the keyword blocking filter.
11.1.2 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”.
11.1.3 Before You Begin
To use the Trusted screen, you need the IP addresses of devices on your
network. See the LAN section (
Section 11.4 on page 216 ) for more information.
