Content Filtering
14.1  Overview
This chapter provides a brief overview of content filtering using the embedded 
web GUI.
Internet content filtering allows you to create and enforce Internet access policies 
tailored to your needs. Content filtering is the ability to block certain web features 
or specific URL keywords.
14.1.1  What You Can Do in this Chapter
Use the Filter (
) screen to restrict web features, add 
keywords for blocking and designate a trusted computer.
14.1.2  What You Need To Know
The following terms and concepts may help as you read through this chapter.
Content Filtering Profiles
Content filtering allows you to block certain web features, such as cookies, and/or 
block access to specific web sites. For example, you can configure one policy that 
blocks John Doe’s access to arts and entertainment web pages.
A content filtering profile conveniently stores your custom settings for the 
following features.
Keyword Blocking URL Checking
The NBG4115 checks the URL’s domain name (or IP address) and file path 
separately when performing keyword blocking. 
The URL’s domain name or IP address is the characters that come before the first 
slash in the URL. For example, with the URL 
www.zyxel.com.tw/news/
pressroom.php
, the domain name is 
www.zyxel.com.tw
.
