  You have a network interface with 2 IP addresses.  (i.e. aliases).
FreeRADIUS is receiving packets on the alias IP address, but sending
responses from the main IP.  This is because the *kernel* makes this choice.

  Make FreeRADIUS listen on the alias IP (and not "*").  Or, enable
udpfromto via the "configure" script.  Once that's enabled, the server
will receive the destination IP of the RADIUS packet, and use that as
the source IP.
