5-26 Firewall Security and Content Filtering
v1.0, January 2010
You can apply the keywords to one or more groups. Requests from the PCs in the groups will
be blocked where keyword blocking has been enabled. Blocking does not occur for the PCs in
the groups where keyword blocking has been disabled.
You can bypass Keyword blocking for trusted domains by adding the exact matching domain
to the list of Trusted Domains. Access to the domains or keywords on this list by PCs in the
groups where keyword blocking has been enabled, will be allowed to pass without any
blocking.
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 “.”.
