  Ok.  Both the server and radclient now use the same code to match
replies to requests, so it's expected that they will have the same issues.

  Try running a test system outside of the jail.  If that works, then
the problem will at least be narrowed down to the jail.

  Or, just install & run it outside of the jail.

  That looks OK.

  Another option is to instrument src/lib/packet.c, function
lrad_packet_cmp().  Have it print out WHAT it's comparing, and WHEN it's
returning.  You'll get a lot of spurious output, but you'll also find
out why the reply isn't being matched to a request.

  It may be that the client is binding to one IP address, and the reply
is sent (and seen as received by) another IP address.
