Run scp to machine R, which is only accessible through gateway machine G.

Step 1: Establish SSH tunnel. Pick a temporary port between 1024 and 32768 (1234 in this example). Port 22 will be used by scp.

$ ssh -L 1234:<address of R known to G>:22 <user at G>@<address of G>
# Adding "cat -" will keep it running while above will get you connected to G
$ ssh -L 1234:<address of R known to G>:22 <user at G>@<address of G> cat -

Either way you run it, open another terminal for next step.
