Chapter 14 Content Filtering

NBG-417N User’s Guide

The following section contains additional technical information about the NBG-
417N features described in this chapter.

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 NBG-417N checks the URL’s domain name or IP address when 
performing keyword blocking.

This means that the NBG-417N 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 NBG-417N 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 NBG-417N check all of the characters in the URL.
