Thanks for that Steven. Connecting this way is only a deviation from the usually connection we use. I have several users you have X-win32 configured on their laptops on the road. I was hoping to make this change invisible to each existing user and their setup since we will be going back to the previous direct X-Win32 ssh connection soon. I'll look at the -R option that you mentioned which I was not aware of.
