is it possible in uNet to shoot a network.spawned bullet but not have it damage yourself?

I am making a 2d platformer shooter online. but whenever I spawn a bullet from a client and that client teleports into the bullet the bullet damages the client. This makes me so sad and i have been trying this for to long. so that is the reason why I am asking a question. If you might ask what my script is. Thanks in advance for trying to find a solution.
