When users (Client PCs) make Internet requests, the traffic
flows (1) through the network path without interruption. The
Web Filter captures the request as the user's request (2)
leaves the network. The Web Filter then determines the
action (3) to either block or pass the request. If the Web
Filter determines to block the user's request, a block
message (4) is sent to the user plus a terminate message
(4) is sent to the Internet server.
A Web Filter set up in the invisible mode can also work in the
router mode. Figure 1:1-2 illustrates an example of a
monitor mode setup, with the Web Filter connected to the
managed switching hub. In this setup, the Web Filter port is
configured with the port monitoring function enabled, so that
the Web Filter's port mirrors the port connected to the
router.

In the invisible mode, the Web Filter performs as a standa-
lone server that can be connected to any network environ-
ment.
