I have just set up a new Windows Server 2012. Everything work, except I cannot connect to the remote desktop from locations outside the LAN (out of the building).
The RDP work fine on the domain from one workstation to another and from a workstation to the server and from the server to the workstations.
When I enter the static ip address of the router remotely, it comes back and says cannot connect.
I am using a Comcast modem. Is there any port forwarding on the modem? I have the port 3389 forwarded to the server in the router.
How do I progressively test where the break in connection is?
