Also there are numerous providers out there that change the public IP addresses every now and then, so you run the risk that that happens for a DJ. I think you're choosing the difficult way, mainly because in your setup every DJ has to do the firewall/router/NAT things on their PC and network, because you are connecting to their PC. Most likely there are HowTo's for your provider/router available online, look for 'NAT' 'Open port outside' or something like that and your provider/router type. Then you still have (2) to go depending on your internet provider you could try to open up the port on your modem/router and forward the port to your streaming PC. If that works then your PC (Windows) is allowing a connection. (1) can be checked by trying to listen from another PC on your own network.

The problems you face are (1) a possible firewall on your PC and (2) your internet provider uses a modem/router that 99.9% sure uses NAT to your internal network. So you're trying to open up a stream to be able to connect to from within RDJ.
