Firewall Web Pages Group
Web Content Filter and Parental Control Web Pages
These pages allow you to enable, disable, and configure a variety of firewall features associated
with web browsing, which uses the HTTP protocol and transports HTML web pages. On these
pages, you designate the gateway packet types you want to have forwarded or blocked. You can
activate settings by checking them and clicking Apply. Here are some of your choices on the
Parental Control page:
•
Activate Keyword Blocking and specify some keywords in the Keyword List to cause blocking
of web pages on the WAN side with the specified keyword in the content.
•
Activate Domain Blocking and specify some Domain Names (e.g. disney.com) in the Domain
List.
Other types of web-related filtering features can be activated from the Web Content Filter page,
including Filter Proxy, Filter Cookies, Filter Java Applets, Filter ActiveX, Filter Popup Windows,
and Firewall Protection.
If you want the gateway to exclude your selected filters to certain computers on your LAN, enter
their MAC addresses in the Trusted Computers area of this page.

Local Log and Remote Log Web Pages
The gateway builds a log of firewall blocking actions that the Firewall has taken.
Using the Local Log page lets you specify an email address to which you want the gateway to
email this log. You must also tell the gateway your outgoing (i.e. SMTP) email server’s name, so it
can direct the email to it. Enable Email Alerts has the gateway forward email notices when
Firewall protection events occur. Click E-mail Log to immediately send the email log. Click Clear
Log to clear the table of entries for a fresh start.
The log of these events is also visible on the screen. For each blocking event type that has taken
place since the table was last cleared, the table shows Description, Count, Last Occurrence,
Target, and Source.

The Remote Log page allows you to specify the IP address where a SysLog server is located and
select different types of firewall events that may occur. Then, each time such an event occurs,
notification is automatically sent to this log server.
