Many months ago when configuring a Barracuda Web Filter 310 I came across a “hidden” expert menu which provides extended options (some of which are not advertised by Barracuda Networks) which may be useful within your environment.

To access this hidden menu you simply load up the admin interface on your Web Filter then click on the “Advanced” tab. Once the Advanced page displays, click in your location bar of your web browser and at the end of the URL listed add &expert=1 .. So for example your URL would look something like:

http://ipaddress:8000/cgi-mod/index.cgi?&user=admin&password=hash&et=1265483069&auth_type=Local&locale=en_US&primary_tab=ADVANCED&expert=1
