If UPnP is not available, it is possible to specify a port for the drafting server and manually configure your router to port-forward that port. Port-forwarding is different for every router , and is only recommended for advanced users. Currently the external port needs to be the same as the internal port. In the future, there may be an option within NautDrafter to define the external port as well as the internal port so that the external port will not need to be the same as the internal port. See this article from HowToGeek for general steps on how to set up port forwarding. Hosting a NautDrafter server just requires TCP to be forwarded.
Screenshot: Example of the config page for a router that has been configured to port forward for NautDrafter.
