I'm trying to evaluate how the traffic flows between x2go and my laptop within 
a 3g connection, maybe i'm seeing it bad, but it seems that when connected to 
a rdp server inside a x2gosession both the traffic when watching a youtube 
video and transfering a 16MB file arrive at the same port, in my case both 
connection when watched with iftop are receiving all traffic at my port 33349 
and being transmitted at :44126 server port. Is this normal ?

I've watched both at the server and at my end.

Thanks for your reply
