A brace from Reece Styche helped Forest Green to an emphatic win at Alfreton.
The visitors took the lead with Jamie Turley's right-footed shot but Theo Streete powered home a header from Josh Law's fine pass to level the scores.
Charlie Griffin restored Rovers' lead with a header from James Rowe's cross before Styche scored from long-range and added another from 18 yards out.
Streete's own goal made it 5-1 and Yan Klukowski completed the rout when he converted from another Rowe delivery.
