The main question:
How do I make my Sharepoint 2010 website available publicly through an established sub-domain using port 80?
Ok, some of the basic info first:
The site is up and running on a custom port (41472). When I go to http://sub.domain.com:41472, I can successfully see the site, log in and work on it, no issues there. DNS is pointing in the right direction and all, but when I've attempted to configure Sharepoint 2010 and IIS to listen on port 80, I can't get in from the Internet. However, Internally, port 80 works fine, I can type the server name and the Sharepoint site loads, so my suspicion is that the problem lies on the IIS side.
Here's what I've done:
* I've extended the Sharepoint site in the Internet zone and chosen port 80, creating a new IIS site in the process.
* I've added the public URL in the "Edit Public URLs" section of Sharepoint 2010 Application Management
* I've added port 80 bindings in IIS for the new IIS website created by Sharepoint's extension.
Suggestions would be greatly appreciated!
