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.

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.

 

 

 

 

Denied Access

Enter a message to be displayed when content filter blocks access

 

Message

to a web page. Use up to 127 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 262 characters (0-9a-

 

 

zA-Z;/?:@&=+$\.-_!~*'()%). For example, http://192.168.1.17/
