This chapter provides a brief overview of content filtering using the embedded web GUI.

needs. Content filtering is the ability to block certain web features or specific URL keywords.

keywords for blocking and designate a trusted computer.

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.
18.3.1  Content Filtering Profiles
A content filtering profile conveniently stores your custom settings for the following features.
Restrict Web Features
The Router can disable web proxies and block web features such as ActiveX controls, Java applets 
and cookies.
Keyword Blocking URL Checking
The Router 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
.
The file path is the characters that come after the first slash in the URL. For example, with the URL 
www.zyxel.com.tw/news/pressroom.php
, the file path is 
news/pressroom.php
.
