I can't join any other people because I just get that error. From what I read online I have to put the Wii in the DMZ. Whaaa??!? Why would they do this? I have a double NAT, I don't even know if that would work, is there not an easier way like just forwarding a port or something? I HAVE to use my ISP's router so I don't have a choice by having a double NAT.
