How to log in node02 03 or any

Dear All,
As my case, I firstly log in node01, automatically, but my work node is node02. And I want to upload files to node02 from local PC with WINSCP.
So how to achieve this?
Thanks a lot.

Please read documentation:
https://winscp.net/eng/docs/guide_tunnel

If that does not help, come back.

Many thanks for your help.
As I am a fresh user of Linux and winscp, thus, many technical terms in the documentation that you posted really confused me.
So, would you please show me the direct settings or commands.
Again, thank you for your help.

I believe the documentation shows all "direct settings or commands" needed.
If you have problems with understanding specific steps, please ask more specific questions.
