The "Add; IP"
In the server cfg is not really necessary.
The port must be open from your router(which u have done)
There is no need to add the port to the Windows Firewall becouse when u launch it it will ask u to allow accsess.
Also what's the rang of your DNHS on the router ?

And the "Remote port" you asked for is the port that allowed your computer to be remote controlled by other machines(Mac/Windows)
