I have a very simple problem, but the methods I've used in the past do not seem to be working in this case. I am attempting to teach myself network coding in Java, which requires connections between computers. For this reason, I've tried opening/forwarding ports on a certain computer acting as "the server".
Windows 8, Verizon FiOS router, firewalls disabled, port X forwarded from router to device.
Both the top two hits for "Open port checker" in google say that the port is not open (one says further: Connection Refused).
My router firewall is at low settings (all inbound and outbound accepted minus the spam port 25), the port X is forwarded to my device (and says Active on the router config page), and my W8 device has its Windows firewall disabled. (None other ever installed).
Am I doing something wrong? I used to do this all the time for gaming, but it's been a few years and I'm doubting myself.
Thank you for your help, AK
