I have the pcwrt for wireless, connected to a linksys 4200 with wifi off. I set the pcwrt MAC as a DMZ host on the 4200 for online gaming for a Wii U wirelessly connected to the pcwrt. Pcwrt UPnP is on. It’s not working though. The Wii U can’t connect to the gaming server and the pcwrt status page still shows the Internet IP address assigned by the 4200 instead of an external one. Please advise.
