Authentication Servers: Duo Security Proxy

  • I am running Duo Security Proxy on Windows ( with [duo_only_client] (Duo only authentication) integrated into pfSense (2.1.4-Release i386) via radius (System > User Manager > Servers > (Radius & Authentication).  Duo is logging and pushing its 2FA and approved / accepted when I attempt to authenticate (Diagnostics > Authentication) but pfSense is showing a “Authentication Fail”.  I have changed the /etc/inc/ timeout and maxretrys (  Is there a log on pfSense to see what is happening or any help would be greatly appreciated?

    PS. Would love to see a package that integrates the proxy onto the system or integrates it natively.
