The iframe module allows me to set it to either a URL (external site) or a file (on my website).

However, I can't figure out how to set it to a webpage on my website.

 

P.S. I don't want to use the http://www.mydomain.com/webpage/default.aspx cuz I got domain pointers.  Instead I just want to set my iframe to just point directly to my webpage  /webpage/default.aspx (without the http:// thingy)

 

That page is a page I create outside of DNN.  So in other words, my dnn website will have an iframe which contians a page I created using frontpage (a htm page)

Easy way to do what you want to do is to save the external webpage as a file on your computer. So it would look like "mywebpage.html" and then use the iFrame to open up the file to display your webpage.
