Hey everyone, I'm really stuck trying to get my Minecraft server ports open. I've tried a TPLink Archer AX20 router and even disabled the firewall. I also turned off IPv6 and changed my IP to a public one that costs about $50 (the ISP gave me an IP from ip-matching.com). Nothing worked except opening port 80 for remote access, and turning on DMZ didn't help either. Please share some tips if anyone else has this problem 😅

There are three main things you need to make port forwarding work. 1. First, you really need a real public IP address that is assigned to your router, which you say you already have. 2. Then, you must set up those port forwarding rules correctly. 3. Finally, the program you use has to actually be running on the port you think it should be and send back what you ask for. I would always start with the DMZ setting because it is not as confusing to setup on some routers. I will remove all port forwarding rules and just use the DMZ until everything works. Try testing the server by getting from your phone or computer inside your local network using that local IP address. This helps you make sure the program itself works fine when there are no other tricks involved. When you think you have all those three things, it is going to be a lot harder. What you need to do right now is try testing each part separately. You can probably put a firewall rule in your router that blocks traffic like this to see if you get messages saying the traffic was blocked. If you see that message, then you know at least the traffic is getting through to your house. Next, you need to check if your server receives the traffic from your router on the right ports and if it does, does it send back? Even though there can be a lot of data, I would use Wireshark on my computer to watch what happens. You want to make sure nothing else runs than just your server program so you don't create extra network traffic. Of course, Wireshark has the option to filter for only what you want but if you have never used it before, it is easier just to capture everything and look through that file yourself. What you want to see is a little bit of internet traffic coming from some IP on your computer into your PC on the port where your server is running. Then hopefully, you will see the response your server sends back.
