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 Web
Filter—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 Web Filter will be affected if the caching
proxy server contains unfiltered, "bad" cached pages. M86
recommends that cached content is cleared or expired after
installing the Web Filter.
WARNING: Contact a solutions engineer at M86 Security for
setup procedures if you wish to use the firewall mode.
