I have a question about filtering through a Cisco VPN. I found the instructions for setting this up, listed below. My question is about step 4, Turn off Client IP Visibility. I need this to stay on, can I still filter through a VPN while keeping this option ON?
  • Create a rule in your firewall blocking all port 80 traffic outbound.
  • Have that traffic re-directed to the Barracuda.
  • Then create a rule allowing all port 80 traffic coming from the Barracuda Web Filter specifically to be allowed.
  • Turn off the Client IP Visibility option on the Basic > IP Configuration (on 5.x firmware this is under the Expert Variables tab) page, effectively enabling the Barracuda as the source IP for all outbound packets. (this option is off by default)
  • Lastly, on Basic > IP Configuration set Enable proxy on WAN to Yes.

Hi Kevin,

To answer your question, no, client IP visibility must be off to filter VPN traffic with an inline deployment.

There should be a way to add exemptions for the client visibility option. Say to always act as "off" for selected subnets.

I too agree and urge both you and the original poster to post under feature requests.
