This chapter shows you how to configure content filtering. Content filtering is the ability to block certain
web features and specific URLs.
Ke ywo rd Blo c king URL C he c king
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
www.zyxel.com.tw/news/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”.
