Access CMS content from outside Portal

[toppac]

I am trying to access an HTML file from outside my portal environment. Essentially I want to have a link to a help document inside the portal that opens a popup window to just serve an HTML file. However every time I try to access the URL it just serves back the default page of the portal. The URL I am trying to access is

https://localhost:8443/portal/content/default/index.html

I'm am trying with the default index page for now until I can figure out how to serve content. Ideally I would want to server up

http://localhost:8443/portal/content/help/index.html

This would then have links to other documents in the CMS repo.

I tried using just /content instead of /portal/content with the same results. Can someone point me to the correct way to server content from the portal CMS?
