Wrexham and Peterborough kept their unbeaten records in a stalemate at a blustery Racecourse Ground.
The Dragons found the greater fluency after half-time as Chris Llewellyn hit the bar and Neil Roberts had a shot cleared off the line.
Posh had their own chances and Dean Holden and Richard Butcher were just wide with good efforts.
Matt Crowell nearly won it for Wrexham at the end, but his injury time free-kick hit the Peterborough bar.
