Since you get the same error browsing the site locally, you know it isn't firewall rules. Did you enable ASP.Net within the Windows features on your server? If not, this will not work. Open Server Manager, and click Roles. You will see Web Server listed.
Click on that. You can then add features from there. Make sure that Asp.Net 3.5 and 4.0 are installed. After doing that, your site should load as expected.
