For the sake of clarity:
The router settings you describe, except port forwarding, are just for the built-in update client, this is to keep your changing IP address information updated at Dyn. It is unrelated to the connections.
Server : http://www.dyndns.org
No, this is most likely
members.dyndns.org, but doesn't seem to matter.
So, now, what problem do you face that you seek for help here?
I can RDP connect without any problem with
dimpoly.dyndns.org, getting your Windows 7 Ultimate login screen, with the message "Dimitris logged on remotely from COMPAQ". So, what's left?
