Access Control defines restrictions on the types of requests that may pass from the
home network out to the Internet, and thus may block traffic flowing in both direc-
tions. It can also be used for allowing specific services when maximum security is
configured. In the e-mail example given above, you may prevent computers in the
home network from receiving e-mail by blocking their outgoing requests to POP3
servers on the Internet. There are numerous services you should consider blocking,
such as popular game and file sharing servers. For example, if you want to make
sure that your employees do not put your business at risk from illegally traded cop-
yright files, you may want to block several popular P2P and file sharing applica-
tions.
To allow or restrict services:
Click 'Access Control' under the Firewall menu. The 'Access Control' screen
appears.

The Address drop-down menu provides you the ability to specify the comput-
er or group of computers for which you would like to apply the access control
rule. You can select between any, a specific computer in your LAN, or 'User
Defined'. If you choose the 'User Defined' option, the 'Edit Network Object'
screen appears. Specifying an address is done by creating a 'Network Object';
to learn more about network objects, refer to Section 9.9.2.
