Filter Failover Mode

Filter Failover Mode determines how iPrism will respond in the event that a filter list error occurs and
iPrism cannot perform its normal filtering duties. Filter failures occur when a filter list fails to
download, or when iPrism is unable to download a fresh filter list for an extended period of time
(typically 30 days).
Note: iPrism will send an email to the administrator's email address (as defined
in the Registration tab) if it is unable to download a filter after 3 days.
To configure filter failover mode:
• In the System Preferences window, in the Filter Failover Mode frame, select an option:
• Pass Traffic (Unfiltered): This setting allows all Internet traffic to pass, as though all
categories are allowed access. Users will have full access to the web.
• Block Traffic: This setting effectively blocks all HTTP activity, not allowing any web surfing to
occur until the problem is resolved and the filter list can be updated. If in bridge (transparent)
mode, all other services will work normally.
Note: Regardless of the option you choose, the rest of your network will
continue to work normally if iPrism is not operating.
Setting or Changing the Supervisor Password
To set or change the password for the iPrism administrator:
