Keyword filter blocks access to webpages containing specified 

keywords.

To set up a keyword filter:
1.  From the navigation panel, go to Advanced Settings > 

Firewall > Keyword Filter tab.

2.  On the Enable Keyword Filter field, select Enabled.
3.  Enter a word or phrase and click the 

button.

4. Click 

Apply.

•  The Keyword Filter is based on a DNS query. If a network client has 

already accessed a website such as http://www.abcxxx.com, then 

the website will not be blocked (a DNS cache in the system stores 

previously visited websites). To resolve this issue, clear the DNS cache 

before setting up the Keyword Filter.

•  Web pages compressed using HTTP compression cannot be filtered. 

HTTPS pages also cannot be blocked using a keyword filter.
