The NBG6716 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

Repeat this procedure to add other keywords. Up to 64 keywords are allowed.

you that the content filter is blocking this request.
