Hey whats up I'm new to this forum so I hope I'm posting this right.

Ok so my problem is that I have created a server in python that is on a certain port, and I have setup port forwarding so that all traffic on the specified port is sent to that port and ip. So far that works the only problem I am having is that once they are connected how does the server send back to the client if it does not have port forwarding set up and all that.

Thanks in advance.
