33.3 Content Filter Trusted Web Sites Screen
Click Configuration > UTM Profile > Content Filter > Trusted Web Sites to open the Trusted
Web Sites screen. You can create a common list of good (allowed) web site addresses. When you
configure Filter Profiles , you can select the option to check the Common Trusted Web Sites list.
Use this screen to add or remove specific sites from the filter list.
Forbidden Web Sites This list displays the forbidden web sites already added.
Enter host names such as www.bad-site.com into this text field. Do not enter
the complete URL of the site – that is, do not include “http://”. All
subdomains are also blocked. For example, entering “*bad-site.com” also
blocks “www.bad-site.com”, “partner.bad-site.com”, “press.bad-site.com”,
and do on. You can also enter just a top level domain. For example, enter
“*.com” to block all .com domains.
Use up to 127 characters (0-9a-z-). The casing does not matter. “*” can be
used as a wildcard to match any string. The entry must contain at least one
“.” or it will be invalid.
Blocked URL Keywords This section allows you to block Web sites with URLs that contain certain
keywords in the domain name or IP address.
Add Click this to create a new entry.
Edit Select an entry and click this to be able to modify it.
Remove Select an entry and click this to delete it.
# This displays the index number of the blocked URL keywords.
Blocked URL Keywords This list displays the keywords already added.
Enter a keyword or a numerical IP address to block. You can also enter a
numerical IP address.
Use up to 127 case-insensitive characters (0-9a-zA-Z;/?:@&=+$\.-
_!~*()%). “*” can be used as a wildcard to match any string. Use “|*” to
indicate a single wildcard character.
For example enter *Bad_Site* to block access to any web page that includes
the exact phrase Bad_Site. This does not block access to web pages that
only include part of the phrase (such as Bad for example).
