OK... so you are connecting from the outside.

Is there a port forward or tunneling option available or possible?

Hmmmmm.... I'm currently unsure of how you could get that to work.

One thing comes to mind, but i have nothing to test i on....  This 
involved ssh-ing into the gateway and running the scp from there...

:$ ssh gateway 'scp me at remote:/usr/local/bin/filename 
user at internal:/user/local/bin/filename'

As far as what you indicated you are trying to do, I'm keen on seeing 
any other responses that may shed greater light on accomplishing this task.
