Apparently its something to do with a strict NAT
I tryed enabling Upnp and Dmz and port forawrding but nothing worked.
Anyone know how to fix?

Bumping this old thread because I have the same issue (and I am not the only one)
There was a thread on Reddit with no real conclusionand the official page isn't helpful either.
I'm considering putting my Wii U in a DMZ but I'm not sure if that's smart.
Any ideas?
(Apparently I don't have enough posts yet to post the links but you can find the links easily if you just google the error code 118-0515)

Have you tried making the thread in /r/smashbros? I am sure someone will help you over there

Like I said, there is already a thread about that on there. This is the topmost reply: "Please try these ports, per Nintendo support page: TCP: 80, 443, 6667, 12400, 28910, 29900, 29901, 29920 UDP: 1-65535 (I don't recommend opening the entire range, though)".
Even if I wanted to do that, I can't do that with my router because it needs some of the ports for other functions. I went ahead and called the Nintendo tech support yesterday and they just told me to put my Wii U in a DMZ. It's a bit of a bother because it's only possible to have either my Wii U or my 3DS in the DMZ but it'll be fine I guess.

For people who have this problem in the future, make sure your Wii U/3DS always gets the same IP adress from your router when you do that.

I had this issue since release, but I put my Wii U on my DMZ and now it works fine. There's easy instructions in how to do it on Nintendo's support page, if I remember correctly.
