No i dont, and i disabled all the adapters (including the vpn one which i dont use) except the default network adapter allowing me to log to the internet.
It seems the client (me) try to connect to the server and most likely run a loop, making the connection impossible.
I check the 16000 port status with this tool and the result is fine.
What is really weird is the lack of error message of something (i had the log problem =solved, the port problem=solved) but now i dont know where the problem comes from :/
