Restrict Web Features
The NBG-417N can disable web proxies and block web features such as ActiveX 
controls, Java applets and cookies.
Keyword Blocking URL Checking
The NBG-417N 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 NBG-417N 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 NBG-417N 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”.
