I am having issues forwarding ports on a D-Link DIR-615 router. I have a Windows Server 2012 Essentials set up, including the Remote Web Access (which works properly!). The problem originally is that my client wants to be able to access their PC from outside the network via their iPhones. If I just go to the https://company.remotewebaccess.com
address, the iPhones display just the remote files. Of course, on a PC, they can log in and choose their PC to connect to.
I then thought about forwarding the ports for each PC, and setting up an App on their iPhones with the information put in already. I left the default port 3389
for the Server, then I incremented by one: 3390
for UserA
, 3391
for UserB
, etc. I then set the Private ports in the router page to 3389
and the static IP address of the clients, but each App I try (even from a Windows PC outside the network) tells me This computer can't connect to the remote computer. Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator
.
I then thought about changing the port in the registry, but I'm worried it will break the Remote Web Access version of the RDP. So the question is: Should I change the registry port number on each PC, or can I setup port forwarding another way in the router?
