That's a simple/client server communication ...You will just have to open a port on the server side nat to route it to your server ( even if you use openvpn, ssh, ... you'll have to do it ) A second solution, if you can't translate a port in the nat is using a third computer reachable from anywhere wich "organise" the transfer, both freerunner connect at this third machine as client and the machine make the transmition. Protocol is at you convenience, making a client/server in Qt4 isn't difficult and is well documented ( if you need help, you can contact me )
