  What's a "proxy pool server" ?  What's a "copy pool server"?

  Installation A and B are proxies?

  That doesn't matter.  UDP packets can get lost.  The kernel on tha
proxy can receive a UDP packet, and then toss it before the packet gets
sent to the RADIUS server.

  If FR doesn't see the packet, there will be no message about "missign
packets".
