Hello,
Thank you for your answer.
What I don't understand is that I can see the configuration for standard TCP-port and the UDP-extended port but not the standard UDP-port.
Where can I find it in the preferences window ?
When I force (values choosed for my D-link 604) the UDP-extended-port to the number of the standard TCP-port+3 and I restart, the UDP-extended-port change at a number I didn't choose at all. Each time I start, it is the same.
Is it correct ?
