Hello there! So My friends Wii U and his ISP and their routers are known in Sweden to cause some problems with online play. The ISP supports answer to that is to bridge their routern to another. Anyhow, by using the Google DNS allows him to play online. Unfortuneatly the DNS to block updates blocks his posibility to play online. Since he does not have the posibility to buy a new router. I'm wondering if it would be possible(and enough?) to just block the Nintendo updates server IPs and urls. And if so is there any list of which urls need to be blocked? Thank You for your responsen.
