Welling 2-2 Cambridge
Substitute Nathan Arnold's superb solo goal secured a draw for Cambridge at Welling to continue the visitors' unbeaten start to the season.
The U's went ahead when Ryan Donaldson's shot came off the crossbar and bounced in off keeper Lee Butcher.
Welling levelled with Ross Lafayette heading in from a corner before Lee Clarke finished with his left foot.
Cambridge equalised as Arnold, who had only been on the pitch four minutes, jinked through to score.
Arnold almost won it in the dying stages but fired wide when clean through.
