I had my exchange up and working on a dynamic public IP with port forwarding (HTTPS + SMTP) to my private IP on my ATT Uverse residential router. ATT uverse residential routers do not allow for NAT mapping of a public to a private so you need to put the public IP directly on the NIC. I was warned I may be blacklisted due to having a dynamic IP so I went ahead and switched to a pool of 5 usable static public IPs. I turned off the static private IP on the NIC of my Exchange server so I could assign the public IP.
It now has the public IP but now the exchange console will not load. I get the error in the screen shot. (First SS)
I added my static IP subnet to AD sites and services (Second SS) but no luck.
I did the above because http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/e506edbb-788c-4eb9-8525-f252e78e3044
forum mentioned it.
