I'm consistently seeing OPEN NAT on my single NAT system here. I do believe that the consistency comes from how the consoles are connected to the main router, how the main router is configured, router code and the behavior of uPnP in it's handling of the ports and additional virtual ports when more than one game console is connected. Just how uPnP is doing this, we'd need a uPnP dev/engineer to have a look at this more closely to see what or if anything could be done to have better handling, improve if any, and behavior for two or more connected game consoles under one roof and on one single NAT network. I think overall the community and Mfrg is only working a single game console thinking track. As homes grow with technology, I see more and more homes having more than just one game console/PC. My 2 cents.
