• Keyword Blocking (Domain Name Blocking). You can specify up to 32 words that, should

they appear in the website name (URL) or in a newsgroup name, will cause that site or

newsgroup to be blocked by the VPN firewall.

You can apply the keywords to one or more groups. 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.

You can bypass Keyword blocking for trusted domains by adding the exact matching domain

to the Trusted Domains table. Access to the domains or keywords in the Trusted Domains

table by PCs, even those in the groups for which keyword blocking has been enabled, will still

be allowed 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 websites with other domain suffixes (such as .edu or

.gov) can be viewed.

• To block all Internet browsing access, enter the keyword “.”.
