NBG4615 User’s Guide

The following section contains additional technical information about the NBG4615 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 NBG4615 checks the URL’s domain name or IP address when performing keyword 
blocking.

This means that the NBG4615 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 NBG4615 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.
