Stand Alone Mode
In the Stand Alone mode, the Web Filter functions as the
only Internet filter on the network. This mode is used if there
is only one Web Filter on the network. Synchronization does
not occur in this mode.
Source Mode
The Source mode is used in synchronization. In this mode
the Web Filter is configured to not only function as a content
filter, but also to act as a Centralized Management Console
for all other Web Filters on the network. Whenever a filtering
configuration change is made on the source Web Filter, that
change is sent to all target Web Filters that have been iden-
tified by the source unit via the Synchronization Setup
window of the Web Filter console. This means that all
filtering configuration should be made on the source Web
Filter. This also means that any user-level filter authentica-
tion should be performed on the source Web Filter so that
these filtering changes can be disseminated to all Web Filter
target units.
NOTE: If the failover detection synchronization feature is
enabled, if a target server fails, the source server can be set up to
detect the failed server and perform filtering for that server.
Target Mode
As in the Source mode, the Target mode is used in synchro-
nization. In this mode, filtering information from the source
server will be uploaded to the target server. The only
synchronization setup that needs to be made on the target
server is to ensure that network interfaces are configured for
network communication.
