WebBlocker
WebBlocker is an option for the Firebox® X Edge e-Series that gives you control of the web sites that are
available to your users. Some companies restrict access to some web sites to increase employee pro-
ductivity. Other companies restrict access to offensive web sites.
You must purchase the WebBlocker upgrade to use this feature. For more information, visit the Watch-
Guard LiveSecurity® web site at
http://www.watchguard.com/store .
How WebBlocker Works
WebBlocker uses a database of web site addresses controlled by SurfControl®, a web filter company.
When a user on your network tries to connect to a web site, the Firebox® X Edge e-Series examines the
WebBlocker database. If the web site is not in the database or is not blocked, the page opens. If the
web site is in the WebBlocker database and is blocked, a notification appears and the web site is not
displayed.
WebBlocker works with the HTTP proxy to filter web browsing. If you have not configured the HTTP
proxy, it is automatically enabled when you configure the WebBlocker service.
Configuring Global WebBlocker Settings
The first WebBlocker page in the Firebox® X Edge e-Series configuration pages is the WebBlocker Set-
tings page. Use this page to:
•
Activate WebBlocker
•
Set the full access password
•
Set the inactivity timeout
•
Set an action if the Edge cannot connect to the WebBlocker server
•
Set an action if the WebBlocker license expires
