perfect bounce when a bullet hits a wall

I wanna create bullets at runtime with physical features as the following code. As long as the speed increases to a higher enough number, such as 350.0f, 400.0f, 1000.0f etc, the bullet will pass through the surrounding walls without any bounce and any collision, which is not what I want.

Is there a way to set perfect bounce but the speed regardless ? (the Bounce Threshold is 0, Friction is 0, Minimum Friction Combine and Maximum Bounce Combine)

thanks ~

 // bullet gameobject's physics settings
 bullet.rigidbody.useGravity = false;
 bullet.rigidbody.isKinematic = false;        
 bullet.rigidbody.collisionDetectionMode = CollisionDetectionMode.Continuous;
     
 Vector3 direction = (target.transform.position - bullet.transform.position) 
 Vector3 directionWithSpeed = changeSpeed(direction);
 // to fire a bullet with a force here
 bullet.rigidbody.AddForce(directionWithSpeed)
 
 public float speed = 100f;
 Vector3 changeSpeed(Vector3 src){
     // the problem : there should be a limit on speed
     speed +=10.0f;
     return new Vector3(src.x*speed,0,src.z*speed)
 }
