When i try to port forward it has a gray shadow and i can't add anything dlink dir 601?

It is for minecraft

Well, I don't think I can help you entirely without seeing what the problem is for myself. I CAN however give you a link to a website that could help you out when it comes to port forwarding for things like Minecraft. I've had to do it before when I was making my server and had no clue as to what I was doing. This website has just about every router model and make listed on here and it gives a tutorial for it.

Hopefully this will solve your problem.
