I'm testing wowza and actually streaming something from it, It worked perfectly on my local netword , but when I try to access it from outside using my public ip it wont :
Example:

Here is the local stream address:
http://192.168.1.12:1935/TEST/mystream/playlist.m3u8 -> Works fine of course in local network
http://90.20.21.5:1935/TEST/mystream/playlist.m3u8 -> Does not work !!

Knowing that I did so on my gateway NAT:
application: HTTP
internal port: 1935
external port: 1935
protocol: TCP
device: 192.168.1.12

am I doing something wrong ?

Thanks,
