I have tried using UPNP and it never stays open, it just goes back to moderate. I was trying to setup a DMZ for the xbox but it just kept saying that my ipv4 address was out of range. I'm pretty technically illiterate so any help is appreciated.
Out of range is very interesting. UPnP not staying open is odd too.
Which modem are you using? Do you have your own router that you are using? What IP address are you entering for DMZ?
