Apart from anything else, door downwind is just a bit of a no-brainer in general isn't it? The other way round seems like a recipe for a bit of a miserable time and it defeats the object of having a porch somewhat if any rain just blows straight in.
Thinking about Toby's comment that "the narrowest/lowest part of the tent is always the part you want facing the prevailing wind" and the possibility that having the porch upwind might actually protect the rest of the tent gave me an idea.
If you were expecting a windy night, would there be any mileage in using a small tarp and a couple of walking poles to pitch a 'wind deflector' upwind of the tent? I'm thinking here of this kind of thing (pic attached), on the roof of a lorry cab to push the wind up and over a load on the flatbed behind, or the way fitting a slightly taller screen on the fairing of a motorbike I used to have transformed the experience of riding a long way on it because the wind that used to hit me full in the face was pushed up over the top of my head.
The OP's tent looks pretty big*, if it's for car camping the obvious answer would be to park the car close to the tent on the upwind side if poss.
*(Assuming the OP is for real and not another of those "new account posts plausible looking question and then is never heard from again" type things we've been seeing a lot of lately.)
