Invisible Mode
If the R3000 is set up in the invisible mode, 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 R3000 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
R3000 from any inclusion in the network connection path.
