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 :

Here is the local stream address: -> Works fine of course in local network -> Does not work !!

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

am I doing something wrong ?
