NBG-419N User's Guide
DESCRIPTION
A server that acts as an intermediary between a user and the Internet to
provide security, administrative control, and caching service. When a proxy
server is located on the WAN it is possible for LAN users to circumvent content
filtering by pointing to this proxy server.
The NBG-419N 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.
