I created a new sharepoint site using the Sharepoint Administrator website. It created just fine and setup the database and IIS7 entries as expected. I opened the random port it generated through the firewall. I am able to browse the site and login to it from the Internet outside the network. I cannot login and get to the side inside the network (intranet).
I can get to CompanyWeb (sharepoint default site) just fine. Compared authentication settings and they seem the same. I checked IE8 settings and added it to the trusted sites list. Put the security to low for trusted sites. I get prompted the default 3 times for logon, and then just a blank white page. No problems from outside the network. I am only trying from the server, but have done that before on other servers and sites. Any ideas what is going on?
