 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.

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.
