YOu're better off hosting it locally, tbh. Then you can remove it from the internet if you dont play online at all. I setup 3 servers on my network and use my router to dispense names to them to keep it as short as possible. have one hosted on the router, one RasPi, and one on PC. It is up to you how you do it, but that will be the easiest route. Or use one that is in place. Personally, I setup a virtual access point on the router, isolated the wiiu and blocked internet to that AP. No worries about updates sneaking through and it just works.
