Wroxham climbed up to fourth place in the Thurlow Nunn Premier Division after victory at Gorleston.
The game at Emerald Park got off to an amazing start, with three goals inside the opening 18 minutes.
It was the hosts who started the ball rolling when Nelson Calinhas scored with 12 minutes gone.
But Wroxham turned the game on its head with two quick goals – from Cruise Ndzadayo and Jordan Bond – and it stayed that way until full-time.
Swaffham Town came out on top after a thrilling finale to their FA Vase second qualifying round replay against Framlingham Town.
Their first meeting on Saturday had finished goalless, but the visitors took the initiative at Shoemakers Lane with a 31st-minute goal from James Mayhew.
But the Pedlars were back in it six minutes from time when Joe Jackson headed home from a free-kick, with Alex Vincent grabbing a winner for Swaffham in time added, prodding home a loose ball.
