Shaun Whalley's late penalty rescued a point for Southport against Dartford.
Harry Crawford poked in to give the Darts the lead, before Andy Owens took advantage of keeper Marcus Bettinelli's error to level.
Dartford were back in front when Tom Bonner finished after Danny Harris's header was cleared off the line.
But Whalley picked himself up from Jon Wallis's challenge in the area to convert an 83rd-minute spot-kick and earn a share of the points.
VIEWS FROM THE DRESSING ROOM
Southport manager Liam Watson told BBC Radio Merseyside:
"To be honest, I don't think the game got going.
"What disappoints me is that we've conceded two from set-pieces and we shouldn't be doing that.
"We got ourselves back in the game and we had a couple of chances before the first goal.
"It was two even sides. We both could have nicked it late on and 2-2 is probably a fair result."
Dartford defender Tom Bonner told BBC Radio Kent:
"It's always good to get on the score sheet but it's disappointing to go in front and lose the lead and to do it twice. We're gutted today.
"I thought we stood up to them really well. It was a lack of concentration for the penalty and we're gutted we didn't get three points today. We thought every 50-50 went Southport's way.
"We need to be tougher to beat, we haven't won in 10 (away) and that's not good enough. We need to cut out the silly mistakes, especially when we go in front, but we haven't been played off the park all season."
