Remote Development with NSight 6.5 with "indirect" ssh

Suppose I can log in a gpu sever named gpu1.sp.sw, and I can further jump to other server using “ssh gpu-2”, “ssh gpu-3”, etc., but I cannot directly log into gpu2.sp.sw. If I want NSight 6.5 to run and debug on gpu-2 or gpu-3, how can I do it?
