Sometimes I have trouble playing certain games online with both my 3DS and Wii U. Typically setting either of them to the DMZ will work, but unfortunately only one device can be in my router's DMZ at a time. I can change the settings each time I want to play online, but that's work I'd like to avoid if possible.
Port forwarding also works if I do the full range, 1-65535. Sadly, however, port forwarding the full range for the 3DS kills my Wii U's ability to connect. Are there specific ports for the Wii U and 3DS that I can forward separately to allow both of them to connect without me having to change the settings every time I want to play one or the other one? Or is there another solution entirely that I'm overlooking?
Worst case, I suppose, I'll just have to change which device is in the DMZ any time I want to play online. It's frustrating, but it works. It would be wonderful if I could avoid having to constantly reconfigure my router and just set it up once and for all.
