node.js - Access private http server -

I have created a Nodes JS server that is running on the localhost: 3000.

How does a request for a private HTTP server go out of the local area network? Manning with router is not an option; The process should be automated.

I have looked at various techniques - and I am confused:

1. map localhost port to external IP address) < Li> SQX ()
2. Connect method to the request header

   It seems that everything is designed for tunneling a customer through a firewall, I have a firewall And want to tunnel a request through a private server or just run the local host port on the external IP

   Any help would be appreciated. Confused.

   1. Configure port forwarding on your router - you said it is not a possibility
   2. Use UPnP Ask your router to open a port - it is often disabled due to security because it is a security risk, but if not,
