Of course the question is do you want to use Tunnelling? It creates a significant performance hit.
If you don't then your solution is a probably a simple case of opening up TCP Port 4747 from the client to the server (note this will also need doing in the Windows Firewall on the server if you have it turned on).
Attached you will find my document on tunneling. Look at the very bottom for tips on your issue. It appears you have a mismatch in server names.

In you image you have fc8qlikso3 and fc8qlikspv.
You will need to change the link machine name to fc8qlikspv.
