Hello, my server is located in local network. All network has only one external IP address.

I made remapping ports on network router for wowza server (internal server’s local ports to external from outside access) 80-\> 20080 8086 -\> 28086 1935 -\> 21935

All features via http protocol work correctly but rtmp streaming don’t work.

In JW player code I use such settings:

image: “[http://185.201.31.133:20080/jwplayer/video.jpg](http://185.201.31.133:20080/jwplayer/video.jpg)”,

provider: “rtmp”,

streamer: “rtmp://185.201.31.133:21935/cam1”

Should it work correctly?

Can I remap ports for streaming? Or should I use only 1935 external port for accessing players to stream?

This is how to add ports to Wowza:
