3 No configuration is necessary on the client machines. The Firewall will

intercept any HTTP requests for external URLs and will forward the traffic

to the Webcache.

Specifying Intranet

Settings

In some cases, it is desirable to prevent access to certain resources by

unauthorized users on the LAN. For example, a school’s administration

office may be placed behind the Firewall to restrict access to its

computers by users in the Student Computer Lab. Similarly, an

organization’s accounting, research, or other sensitive resources may be

protected against unauthorized access by other users on the same

network. By default, protected LAN users can only access the Internet and

no other devices between the WAN port and the Internet. To enable

access to the area between the Firewall’s WAN port and the Internet

(referred to as the intranet), you must specify intranet settings for the

Firewall.

To achieve internal firewalling, connect a second Firewall between the

unrestricted and the restricted segments on the LAN, as shown in

Figure 51. In this diagram the Firewall labelled F2 is protecting an internal

network.
