   configure server and router for udp
  Hello everybody,at the moment I am developing a 3d social community. At the moment I do have written a server and the community itself(both pre-alpha). The communication uses UDP to transfer data. In my local network the communication works fine, so that I want to try it online.My problem is, I am not sure how to manage the access of my dmz-server from outside with UPD. I have a D-Link Router (I think "sir 305"?).If you need more information, only ask.Best regards, Freeman4gu   
  If the machine is using the IP address configured as the DMZ by your router, then UDP from the outside should get to it automatically (but you'd also get any badness from the outside, like zero-day attacks etc).The safest route is typically to configure a port forward from your router to your internal machine on a single UDP port, so that no other traffic gets in. When you do this, you typically want to set the internal server machine on a fixed IP address, rather than DHCP, so that the port forward address doesn't have to suddenly change.   ;  Thx for the answer, I already tried it yesterday evening on my own and it works fine. But I think you are right, the dmz is the worst solution. In fact that the server (old notebook) has a new installation and get's in a few days selled, I think it doesn't matter for me :-PI am thinking about buying a pc with intel atom to use this as mini-udp-xampp-nas-server after selling my notebook...
