Challenge at the port entrance...
Challenge at the port entrance...
I didn't check the firewall rule before, so I wasn't sure what it was doing. The scanner shows port 58050 is closed. I don't understand why this has been working for years now and suddenly it's not possible. Also, I'm confused about what I'm actually doing. I'm opening ports on my internal IP address? What does the public IP mean? How do I open those ports? Are there other tools I can use to connect to my home desktop for music?
If the port scanner indicates it’s closed, the issue likely lies in incorrect port forwarding settings or configuration problems within your system. It’s best to refer to TPlink’s port forwarding instructions, which I provided earlier, to verify everything is set up correctly. To put it simply: a firewall acts like castle walls, controlling who enters and exits. Each port functions as a gate with specific rules for traffic. When you forward a port, you’re setting a rule so that incoming traffic can reach the host behind the gateway. Without proper instructions for the firewall, the traffic won’t be allowed. The app running outside needs to know the correct destination address (the castle’s WAN), and your router must direct those requests inside the network. This explanation aims to clarify the concept of firewalls in basic terms. Additionally, there are alternative options like VPNs (WireGuard, Zerotier, Tailscale) that could resolve the problem. I personally use Tailscale because I’m on a CGNAT setup.
Initially... I appreciate your detailed breakdown and castle comparison. That really clarified things for me. Honestly, I want to invest more time in learning about Windows networking. I’m eager to gain better control over my home network, internet settings, and so on. While I’m strong with other computer parts, I’m struggling with networking concepts. Whenever internet or home network issues arise, I feel completely confused. I’d love to dive deeper into DNS, optimize my Rpi Kodi installation settings, and explore more examples so I can fully grasp what’s possible with home networking. Still, even though I wish I could master all the router options, your analogy and guidance made a big difference. Thank you for that. After reading your post, I reviewed the parts affecting my connection: router settings through the tplink app, the BubbleUPnP setup (which works almost on its own), and the Windows Firewall configurations. And you’re right—what finally clicked was choosing the Private profile in the Server Properties for the BubbleUPnP rule. I also tried Default and Public, but the BubbleUPnP server test succeeded immediately. I’m not sure why, but it seems only the Private profile allowed access, which isn’t the one Bubble uses. Is that all, or is there more to it?
