Chapter 14 Content Filtering

NBG420N User’s Guide

You can use commands to set how much of a website’s URL the content filter is to check for 
keyword blocking. See the appendices for information on how to access and use the command 
interpreter.

By default, the NBG420N checks the URL’s domain name or IP address when performing 
keyword blocking.
This means that the NBG420N checks the characters that come before the first slash in the 
URL.
For example, with the URL 

www.zyxel.com.tw/news/pressroom.php

, content filtering only 

searches for keywords within 

www.zyxel.com.tw

.

Full path URL checking has the NBG420N check the characters that come before the last slash 
in the URL.
For example, with the URL 

www.zyxel.com.tw/news/pressroom.php

, full path URL checking 

searches for keywords within 

www.zyxel.com.tw/news/

.

Use the ip urlfilter customize actionFlags 6 [disable | enable] 

command to extend (or not extend) the keyword blocking search to include the URL's full 
path.

Filename URL checking has the NBG420N check all of the characters in the URL.
For example, filename URL checking searches for keywords within the URL 

www.zyxel.com.tw/news/pressroom.php

.

Use the ip urlfilter customize actionFlags 8 [disable | enable] 

command to extend (or not extend) the keyword blocking search to include the URL's 
complete filename.
