Trouble with turret script

I am trying to finalize a game for school but I'm having a little scripting issue. I get the turret to react to the player when he gets within a pre-determined distance; however my problem is that the turret seems reversed as it's the back that follows the player. Here is the script I am using:

 var target : Transform;
 var range : float;
 var speed : float;
 
 function Update () 
 {
     range = Vector3.Distance(target.transform.position, transform.position);
     if (range<200)
     {
         transform.rotation = Quaternion.LookRotation(transform.position - target.position);
     }
     if (range<150)
     {
         transform.Translate(Vector3.forward*speed*2);
     }
 }
