Thanks for all the help and information.
I was able to hook up a monitor and login using Admin and one of the usual passwords. I checked the user list and realized I might have been using admin or administrator instead of "Admin". I was able to log in the Web GUI and make the necessary changes for no-ip.com and now they can view cameras from a domain name or mobile device app.
My only gripe is that you have to use IE if trying to view on a PC, which means you have to use an app on a tablet instead of a browser.
