LABEL

DESCRIPTION

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.

 

 

Add

Click the Add icon at the top of the column to create a new content filter

 

policy at the top of the list.

 

The Active icon shows the entry is enabled. Click this icon to disable the

 

entry.

 

The Inactive icon shows the entry is disabled. Click this icon to enable the

 

entry.

 

Click the Edit icon to go to a screen where you can change the configuration

 

settings of an entry.

 

Click the Remove icon to delete an entry from the list.

 

Click the Move to N icon, type a number in the move entry dialog box and

 

press [ENTER] to move the entry to the numbered location.

 

Click a content filter policy’s Add icon to create a new content filter policy

 

above the current line. All other entries below the new entry are pushed

 

down.

 

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.

 

 

Denied Access

Enter a message to be displayed when content filter blocks access to a web

Message

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”.

 

 

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.

how to use the Test Against Web Filtering Server button. When the

on page 551).
