After I visited Rye, the next destination was Camber / Camber Sands. Based on the distance on map (the road there is 4.2 miles, but there should be a direct footpath following the River Rother (on the side with the Rye Golf Club).
That was the path I followed walking on a footpath and the road just seem to keep going. After an hour of walking on that path, passing by some farms, a lake and Rye Golf Club, I arrived to my destination.
