Move
To change an entry’s position in the numbered list, select it and 
click Move to display a field to type a number for where you want 
to put that entry and press [ENTER] to move the entry to the 
number that you typed.
#
This column lists the index numbers of the content filter policies.
The ordering of the content filter policies is important as they are 
used in the order they are listed. The ZyWALL checks requests for 
Web sessions against the list of content filter policies (starting from 
the first in the list). The ZyWALL’s content filter feature blocks or 
allows the Web session according to the first matching content 
filter policy and does not check any other content filter policies. 
The ZyWALL does not perform content filter on Web session 
requests that do not match any of the content filter policies.
Status
The activate (light bulb) icon is lit when the entry is active and 
dimmed when the entry is inactive.
Address
A content filter policy applies to web access from the IP addresses 
listed here. any means the content filter policy applies to all of the 
web access requests that the ZyWALL receives from any IP 
address. 
Schedule 
This column displays the name of the schedule for each content 
filter policy. You can define different policies for different time 
periods. none means the content filter policy applies all of the 
time.
User
This column displays the individual or group to which this policy 
applies. any means the content filter policy applies to all of the 
web access requests that the ZyWALL receives from any user. 
Filter Profile
This column displays the name of the content filter profile that 
each content filter policy uses. The content filter profile defines to 
which web services, web sites or web site categories access is to 
be allowed or denied.

Message
Enter a message to be displayed when content filter blocks access 
to a web page. Use up to 255 characters (0-9a-zA-Z;/?:@&=+$\.-
_!~*'()%,”). For example, “Access to this web page is not allowed. 
Please contact the network administrator”.
It is also possible to leave this field blank if you have a URL 
specified in the Redirect URL field. In this case if the content filter 
blocks access to a web page, the ZyWALL just opens the web page 
you specified without showing a denied access message.
Redirect URL
Enter the URL of the web page to which you want to send users 
when their web access is blocked by content filter. The web page 
you specify here opens in a new frame below the denied access 
message. 
Use “http://” or “https://” followed by up to 255 characters (0-9a-
zA-Z;/?:@&=+$\.-_!~*'()%). For example, http://192.168.1.17/
blocked access.
