I think that the problem is in your router, not your computer. When packets come from the Internet, it should be routed to an specific server. You have to configure your router to redirect the traffic on port `3326` to your server. | [

I know of many utilities that can tell me the bitrate of an MP3 file, but I've never seen one that can tell me whether or not the MP3 file is VBR (variable bit rate - the bit rate fluctuates within the file) or a CBR (constant bit rate - the bit rate stays the same within the file).
