Did you try Chrome RD?
I've live in Denmark in a apartment where we got internet in all apartments from our landlort I think we all get the same external IP in all appartmens and all ports in the active equipment is closed I've been told. When i run a port scan all ports are closed it says. ( also port 80?) so I think the equipment is told not to respond on any request.
Is it then possible for me to remote access my home network from outside? When I fill in the ip 10.0.0.1 I've got a login page for the equipment there is placed down the basement that I'm not allow to access for the building owner.
