I want to use an existing Ubuntu machine (with a public IP) to allow a user to SSH into it and then use it to SSH/RemoteDesktop/FTP into another linux machine (with a private IP but within the 1st machine's network).

I would create a new user account for this purpose, but I want to:

  1. Restrict sudo access to this user
  2. Not be able to go into other users /home/otheruser directory

How to do it?

What you are trying to setup is usually called a jumpbox.

Users are not added to the wheel group automatically, so you only need to useradd the new user, and you are good to go
