CHAPTER 21
Content Filter
21.1 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.
21.2 What You Can Do
Use the Content Filter (Section 21.4 on page 158) screen to restrict web features, add
keywords for blocking and designate a trusted computer.
21.3 What You Need To Know
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.
21.3.1 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.
