Router Mode

If the R3000 is set up in the router mode, the unit will act as
an Ethernet router, filtering IP packets as they pass from
one card to another. While all original packets from client
PCs are allowed to pass, if the R3000 determines that a
request is inappropriate, a block page is returned to the
client to replace the actual requested Web page or service.
Since only outgoing packets need to be routed—and not
return packets—the R3000 only appears in the outgoing
path of the network.
Figure 1:1-3 illustrates an example of the router mode
setup, in which the R3000 is set up to act as the Internet
router.

As previously mentioned, an R3000 set up in the router
mode can also work in the invisible mode. The router mode
setup also will work in the firewall mode.
