Impossible to import from Blender to Unity and keep front direction

My problem is simple :
Front view and Blender gives -Y.
Front view in Unity gives +Z.

So to export from Blender to Unity I set FBX setting "up = +y" and "forward = +Z".
IMPOSSIBLE to get my object facing the front view in Unity. I tried dozen of combinations.
The weirdest thing is I had success some days ago for multiple export with the sames .blend files, but now I can't retreive what I did good. hours losted and counting.
Big frustration to have the two best free 3D tools on earth and they just can't talk to each other correctly.

 

This should work, if it is not something rigged and animated. It may still work with rigged/animated but something unexpected may happen later on..
