I have finished my chat program and it works fine in the local network but now i need it to work on a wide scale .... I have tried simply putting in the ip address of were it is heading but without any dmz setting and forwardings ect nothing is going to happen ... so how would i make it happen ?

i want my chat software to talk to the other chat software and its p2p no server inbetween .. and its over the web ... using just the ip address would go straight to the router and get lost i assume??

As long as the listening port is open on the target machine then it should work.
