I have tried running the server on my machine, and then connecting to my internal IP address via her machine. It does not connect. My goal is to run the server on my machine, and have friends from outside my private network connect, as well.
I'm having similar problems using a program which opens a port. My friend in another country is trying to connect, but cannot. I have port forwarded the port number, but it still won't connect. I feel this is the same issue as I am having with the server/client java program.
Are there any thoughts about what might be the issue?
