Air serversocket remote (not LAN) only works in ADL (AIR 26.0)

Im fairly new to this serversocket class but i wanted to develop a simple chat app where you can either HOST a room or a JOIN an existing one.

I opened my router and did some port forwarding..

made the scripts everything works OK no errors. (AIR 26.0 SDK)

I click Test and ADL shows up with my app and click Host. (serversocket fires up on desired port (the one i forwarded in router) and everything works like a charm. Im able to connect to the hosted room over LAN or over the Internet.

What is the problem? You may ask...

Well the problem starts when you build your app and install it and the problem is that it only works in LAN (despite the fact it worked over the internet when it runned in ADL strange... huh?)

I bet this is some invisible security future i dont know about how to terminate.

Would be nice if someone could help me with this. I even tried to compile with older versions of AIR like 3.8 (the version where Air started to support serversocket class with mobile devices)

Still only works in LAN. But Why? why it is that it works when i click Test and it runs within ADL but it not works when i build it and install it.
