appear in the Web site name (URL) or in a newsgroup name, will cause the site or newsgroup
to be blocked by the wireless firewall.
You can apply the keywords to one or more groups in the Apply Keyword Blocking to: fields.
Requests from the PCs in the groups for which keyword blocking has been enabled will be
blocked. Blocking does not occur for the PCs that are in the groups for which keyword
blocking has not been enabled.
If you enter a domain name in the Trusted Domains box, keyword filtering will be bypassed.
For example, if you entered www.netgear.com, keyword filtering will be bypassed for this
domain; however, Web Components filtering still applies.
Keyword application examples:
• If the keyword "XXX" is specified, the URL http://www.badstuff.com/xxx.html is blocked,
as is the newsgroup alt.pictures.XXX.
• If the keyword ".com" is specified, only Web sites with other domain suffixes (such as .edu or
.gov) can be viewed.
• If you wish to block all Internet browsing access, enter the keyword ".".
