How can the customer change operating mode of barracuda web filter?

Barracuda Web Filter, All Firmware Versions

Please navigate to basic > IP configuration tab and right bellow the DNS server configuration, you can set the operating mode to either Active or Audit.

Please note : If web filter is deployed in forward proxy , changing operating mode to Audit doesn't make any difference and web filter still does the filtering but, in inline deployment, setting this mode to Audit will pass traffic without being filtered.
