DESCRIPTION
The NBG-417N can block Web sites with URLs that contain certain
keywords in the domain name or IP address. For example, if the
keyword "bad" was enabled, all sites containing this keyword in the
domain name or IP address will be blocked, e.g., URL http://
www.website.com/bad.html would be blocked. Select this check box to
enable this feature.
Type a keyword in this field. You may use any character (up to 64
characters). Wildcards are not allowed. You can also enter a numerical
IP address.
This list displays the keywords already added.
Click Add after you have typed a keyword.
Repeat this procedure to add other keywords. Up to 64 keywords are
allowed.
When you try to access a web page containing a keyword, you will get
a message telling you that the content filter is blocking this request.
Highlight a keyword in the lower box and click Delete to remove it.
The keyword disappears from the text box after you click Apply.
Click this button to remove all of the listed keywords.
