machinegunjoe Posted October 5, 2009 Share Posted October 5, 2009 so I was building this simple messaging program and I realized that this probably wouldnt work over the internet if both computers were behind routers. I was wondering if their was a way to make it so the routers send the right tcp data-grams(packets) to the right computers without having to log in to the routers admin and set up port forwarding? thanks, machinegunjoe Link to comment Share on other sites More sharing options...

TurionAltec Posted October 5, 2009 Share Posted October 5, 2009 Look up UDP hole punching. Alternatively, if the router has a uPnP interface active, look at one of these programs: http://www.codeproject.com/KB/IP/PortForward.aspx http://www.upnpworks.alcidelic.com/ http://miniupnp.tuxfamily.org/files/ Link to comment Share on other sites More sharing options...
