Firewall/NAT

Hello,

I have a problem using the Mediaplayer of the Android SDK (android.media.mediaplayer) for streaming e.g. youtube videos. This does not work.

All other apps work without any problems. For example also the integrated standard youtube player works. Only the mediaplayer from the SDK does not work with monowall.
I have tested the application with a lot of other internet connections without any problems.
If I remove the monowall and connect the WLAN accesspoint directy to the internet the app is working too -> the problem must be monowall

I have opened the firewall for all incoming and outgoing connections.
The logs are given in the attached picture:
IP 10.10.1.60       Android phone
IP 192.168.7.99   WAN Address of monowall
IP 74.125.210.86 Google server

The strange thing for me is that the destination port of the incoming connection is the port of monowalls WAN interface and not the ip of the Android phone.

Is it perhaps a bug?

Please help me!
