I'm pretty sure I read somewhere that it's working in vWii. As for the vpn, I'm not totally sure. I know I have American Netflix in Wii U mode just by setting the DNS manually in network settings. From my understanding the settings should affect both Wii U and vWii. Have you tried the VPN settings in the Wii U opposed to your router. Not sure if that will help/work, not my area of expertise.
