Are there specific MK8 ports to open? When I enable DMZ in the DD-WRT firmware, my Wii U can't go online anymore...

I already opened some ports for CoD, Blacklist and ´Wii Sports Club. Maybe MK8 uses the same ports as WSC.

EDIT: Ah, DMZ works now, I had to disable the opened ports. Can DMZ cause security issues?

Technically speaking yes. But for something like Mario Kart I don't think there will be any issues. If you ever start hearing about hackers during online or stuff like that the DMZ should be disabled for precaution, but for now I think enabling it should be fine.
