There was a player on my server that showed up in status as having a port number of -7589 whereas everyone else was roughly waht you'd expect in the 28000 range. 
 
 I didn't think a negative number was even possible!?! What could cause this?. Might it be a display bug?
  
 
  
  
    You can set your "qport" as a client to pretty much whatever you want. This is sometimes necessary when you have more than one person on a LAN going through a router that uses NAT. It doesn't really make much difference.
  
 
  
  
    Right, but it wasn't the qport that was negative.
 
 The ip was 65.35.106.16:-7589
 
 Very strange no?
  
 
  
  
    The only report of port for a client via status is the qport.
  
 
  
  
    I trust your opinion Matrix, you seem to know more than anyone about the server settings etc...
 
 This really isn't a big issue, but when I do a status I get both the IP port and the QPORT.
 
 It sorta looks like this:
 
 65.113.118.85:28070 4458
 
 Where the 4458 is the QPORT...maybe Im wrong. and never really looked at how the data lines up to the headers in status, but I swear I saw what I posted earlier.
 
 65.113.118.85:-7589 4458
 
 This is not the exact IP and info...but this is what it looked like.
  
 
  
  
    Yeah, I see what you're talking about. My guess is that they are rerouting ports through their firewall in that manner.
