  That's good.

  What wireshark capture?  Where?

  There isn't much magic here.  If FreeRADIUS sends a packet, it relies on the OS to send the packet.  If the packet disappears...  blame the OS / routing, not FreeRADIUS.

  Track the packet out the interface that FreeRADIUS is using.  Then, track the packet hop by hop across the network.

  Note that wireshark on the same machine MIGHT NOT see the outgoing packet.  It all depends on how the local network stack works.
