  While the attribute is mandatory, FreeRADIUS doesn't use it for anything.

  It will work.

  FreeRADIUS will work if it

  (a) proxies a request containing Proxy-State
  (b) receives a valid response (src/dst ip/port, etc.) with no Proxy-State.

  In your case, the home server is being marked dead because it isn't
responding.  Nothing else will cause it to me marked dead.
