Paul Wanless went from zero to hero as he rescued a point for Forest Green after playing a part in Dagenham & Redbridge's first-half opener.
Chris Moore put the Daggers ahead with a free-kick from just outside the area after Wanless fouled Tresor Kandol.
But the Rovers midfielder made amends when he fired in a penalty after Anwar Uddin brought down Julian Alsop.
Glen Southam then came close for the hosts while Alsop and Ryan Harley had good chances cleared at the other end.
