Hi Jamison,
Just a couple of questions for you.
When you said you port forwarded. Which protocol/s did you forward? As you can see there’s a mix of TCP and UDP that your server is listening for. Are you sure you are forwarding both?
Secondly, is your server/pc configured to use DHCP? If it is, have you reserved your MAC address a specific IP to use? If you’re using a dynamic IP your router will continue to forward ports to whatever address you plugged in and won’t update it if your PC gets a new address.
I’d also suggest getting someone to run a portscan on your public IP and confirm if they can see the ports are open. Use something like nmap (zenmap if on windows) or even just try a powershell line of
Test-NetConnection -Port 2456
I hope this helps you out. Good luck
