Chapter 1: Filtering Operations

Invisible Mode

The ProxyBlocker is set up in the invisible mode, indicating
that the unit will filter all connections on the Ethernet
between client PCs and the Internet, without stopping each
IP packet on the same Ethernet segment. The unit will only
intercept a session if an inappropriate request was
submitted by a client. In this scenario, the ProxyBlocker
returns a message to the client and server to deny the
request, and a block page displays to deny the client access
to the site or service.
Figure 1:1-1 depicts the invisible mode that removes the
ProxyBlocker from any inclusion in the network connection
path.
