Content Filtering; Chapter 15 Content Filtering; Overview; Content Filter - ZyXEL Communications LTE3301 Series User Manual

15.1 Overview

This chapter shows you how to configure content filtering. Content filtering is the ability to block
certain web features and specific URLs.
Keyword Blocking URL Checking
The LTE3301 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.
Since the LTE3301 checks the URL's domain name (or IP address) and file path separately, it will not
find items that go across the two. For example, with the URL
pressroom.php, the LTE3301 would find "tw" in the domain name (www.zyxel.com.tw). It would
also find "news" in the file path (news/pressroom.php) but it would not find "tw/news".
