my port forward broken again.

Hey superstar64,

The issue is likely caused by something on your local network. Port Forwarding is typically managed by a device on the perimeter of your local network. Software such as the Albertino Port Mapper will only work if your computer is plugged directly into your cable modem or if the computer has direct access to modify the perimeter equipment to apply the port forward mapping - most modern networks are not setup this way.

Without more knowledge of your network, it's tough to troubleshoot these sort of problems. Was your port forwarding working prior to upgrading to Windows 10? It's possible there's a port forward open on your network for a certain IP address that's changed when you rebuilt your system.

If you or someone you know has access to your router or wireless access point, see if you can take a look at any port forwarding features for attached devices - this is typically how you would open up port 28000 to the internet. I would strongly advise against posting any inner workings of your network here, but you should be able to pull up an internet search for "Port Forward [name of your router brand]" to figure out how to accomplish this.

Let me know if this helps or if I can provide any further guidance.

Thanks,
