Barracuda Web Security Gateway
Will NTLM Authentication work when my Barracuda Web Filter has been set up using WCCP to route traffic?
Scope:
All Barracuda Web Filter models 410 and above, firmware versions 3.3 and above.
Answer:
No. NTLM (and Kerberos) authentication mechanisms require that the Barracuda Web Filter be a trusted host in the Windows Domain and that it receive traffic directly from the users (as a proxy). In WCCP deployments, the Barracuda Web Filter receives outgoing traffic only after they go to the Cisco Router.
