    Unhappy Client to server connection issue (external ip)


    I used for some time a TS3 server to speak with friends on a local network without problems.

    Now, a friend of mine is trying to connect to my server through internet. He uses my external ip adress (most of the time my dyndns but we checked if there wasn't a problem with it) and can't connect.

    I opened the 9987, 10011 and 30033 ports. Connection failed.
    I tried with a 9986-9988 range. Not better.

    My firewall was switched off.

    I tried this website's test ( ) but it didn't worked (told me there was a timeout). I tried on other ports (like the ones I use for my FTP server which works) and still gave me a timeout.

    The friend is able to connect to other servers (like the one given in some topics).
    I am able to connect to my server in localhost and using the 192.168.x.x adress.

    I don't know what to try now.

    Can someone help me ?

    Already done. No results. Thanks for the reply anyway.

    I suspect something very stupid and that should be obvious but I can't see where the problem could be.

    Do your try (your friend) to connect directly with the IP address (instead the dyndns domain name) ?
    Do you have a modem between your router and the wall plug ?

    Yes, we've tried with the address and the dyndns and it failed.

    I'm connected to the internet with a router and so is my friend. No other equipment at my house or his.

    Port 9987 has to be opened for UDP only! Only some routers support, that it works fpr TCP & UDP at the same time.
    Ha anyone noticed, that does not work with udp?
