Proxy issue - Failing proxied request for user error

[Root, Paul T]

Is freeradius listening on that interface?

Do you have a firewall running on the machine?   If so, tcpdump reads the interface before the firewall application, so you will see it there but freeradius will not.

  It's usually a slow database.

  If the OS doesn't deliver packets to FreeRADIUS, then there's little you can change in FreeRADIUS to fix the problem.
