The firewall mode cannot be used with any other mode
(invisible or router).
Figure 1:1-4 illustrates an example of a firewall mode setup
in which requests are never sent to the caching server. In
this scenario the local caching proxy will not affect the
R3000—even if the server contains unfiltered, “bad” cached
pages—since no request can pass until it is filtered.
Figure 1:1-5 illustrates an example of a firewall mode setup
in which requests are always sent to the caching server. In
this scenario the R3000
will be affected if the caching proxy
server contains unfiltered, “bad” cached pages. 8e6 recom-
mends that cached content is cleared or expired after
installing the R3000.
WARNING : Contact a solutions engineer at 8e6 Technologies for
setup procedures if you wish to use the firewall mode.
