  No.

  Tell the administrator of the remote server to fix his system.

  RADIUS *requires* replies to come from the same IP.  Anything else is
broken.  All RADIUS servers since 2000 or so should be able to work
correctly when they have multiple IPs.

  The remote admin has no excuse for running a broken RADIUS server.
