IDK, maybe. In any case, if you can't get port forwarding to work properly (by whatever means), you can't run the server on your home PC.
If you're ok with renting a dedicated or virtual server, I've personally been using Time4VPS as a promo content delivery server over HTTPS for about a year and it works pretty well. It's not too expensive either. Though be careful as this does require a bit more knowledge in server-setup. I've had some issues settings up the SSL part for HTTP. But to be honest, just running XAMPP on there worked rather well. So you might be able to setup a RMX-OS server there without too many problems.
