The following is a direct copy and paste from a ssh terminal session from the   
   machine demonstrating the problem.   
      
   OS is Ubuntu LTS 12.04

   tcp        0      0 169.54.34.176:843       0.0.0.0:*                 
   LISTEN      459/BattleServer   
   --- cut here --- cut here ---   
      
   This is somewhat backwards, but the single line output from netstat says to me   
   that pid 459, BattleServer is listening on port 843.  This is for the benefit   
   of a Flash client that will attempt to connect there to get a cross domain   
   policy file.   
      
   The upper section is the result of a client trying to connect, all three SYN   
   packets have 169.54.34.176:843 as the destination ip/port, which matches the   
   LISTEN line, and yet the response is RST, ACK, not SYN, ACK.   
      
   I'm completely at a loss as to why this might be happening, but needless to   
   say, things go downhill quite rapidly from here.
