Hello. I have played around quite a bit with DNN on a test box. I then went ahead and installed from scratch on a Windows Server 2012 R2 box. I can login and access it from the inside my domain.

However, once we placed it on the outside of the domain (in a DMZ), I can't access it. I receive:

404 - File or directory not found

I can still access from the inside, so the site still works.

Note: Nothing was moved or ported from another server, this is a base install on this server. I'm merely trying to access from the outside now. I can't figure out what I'm missing.
