Turn on UpnP on my MI424MR router

Trying to set up Windows Home Server 2011. Working on Remote Access, and it is hanging on router. From what I can tell, the issue is related to turning on the UPnP. I have looked in the manual, and when I go to the spot in the router set up where the UPnP enable is supposed to be there is nothing there. Advanced, inbetween these two objects...

Any thoughts?

TIA,
