Solution #00003512

Scope:
All Barracuda Web Filters Firmware Release 3.2 and above.

Answer:
If you want to use your Barracuda Web Filter to monitor traffic without actually affecting anything, you have several options:
  1. Configure the Barracuda Web Filter to be inline (per the administration guide), and set the Operating Mode option on the Basic > IP Configuration page to Audit. This will prevent the Barracuda Web Filter from changing any traffic it sees, but it will still log everything (and the logs will show what the Barracuda would have done if it were set to Active).
  2. If your network uses a WCCPv1-capable core routing platform, you can deploy one or more Barracuda Web Filters as cache engines within the cache cluster serviced by that router (or switch). For more information on this feature, see Solution #00003305. Then, once this has been configured, set all of your policies under the Block/Accept tab to Monitor, rather than Warn or Block. This deployment does not require any client browser settings, and works as a transparent proxy mechanism. Audit mode will not work with a WCCP deployment.
  3. Otherwise, you can configure your Barracuda Web Filter in Forward Proxy mode. For more information on this feature, see Solution #00002367. Then, once this has been configured, set all of your policies under the Block/Accept tab to Monitor, rather than Warn or Block. This configuration requires each user's web broswer to point to the Barracuda Web Filter as a proxy server.
