Sorry to bump an old topic, but when I try to block the addresses listed in my router the Wii's connection test still passes. I can change the mac address that is restricted to my PC's and it can't access the servers, but when I change it to the wii's address it still passes the connection test. This leads me to believe that the router answers the connection and then breaks it. Thus making the wii think the connection was a success, when in fact it was not. However, I haven't the courage to tell it to try to update; why tempt fate? I was just wondering if anyone has tried blocking these addresses with success? Success being: the wii unable to update but still have Internet functionality.
the servers I have blocked are:
