The port forwarding isn't functioning as expected.
The port forwarding isn't functioning as expected.
Ensure your static local IP is correctly configured and matches the one used for port forwarding. If Windows Firewall is interfering, adjust its settings. Your ISP may also be employing carrier-grade NAT, requiring further clarification.
Verify your connection status by matching the external IP from your router settings with the public IP you see online. If they differ and your router IP falls into 192.168.X.X, 10.X.X.X, or 172.16.X.X ranges, you're double-nat. If it's another range, you're likely behind carrier-grade NAT. Also confirm the service using that port is active during testing.
