How to get access via external IP to nginx-rtmp server?

Question

Nginx

I have a GoPro camera that can stream via an RTMP URL. Installed nginx-rtmp server on windows, registered in config:

rtmp {
        server {
                listen 1935;
                chunk_size 4096;

                application live {
            live on;
                        record off;
                }
        }
}

In the GoPro camera, I registered the RTMP address: rtmp://local IP:1935/live/key and started broadcasting. I used the same RTMP address as a media source in OBS, applied various overlays and started broadcasting on twitch.
Everything works within the home Internet, but if I'm going to broadcast outdoors over mobile Internet, what will be the rtmp address and settings?

The one that your provider gives you, if at all
