URL Filtering
14.1 Overview
This chapter shows you how to configure URL filtering. URL filtering is the ability to block certain web
features and specific URLs.
Keyword Blocking URL Checking
The LTE2566-M634 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 LTE2566-M634 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
www.zyxel.com.tw/news/pressroom.php ,
the LTE2566-M634 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”.
