Who is your ISP? What country? How are you getting internet (4G, Cable/Coax, DSL, Fiber, etc)?

How are you testing remote access?

It's possible you've either configured it incorrectly, are behind CG-NAT, or are missing something else.

ok, you're not behind CGNAT at home because I know Spectrum doesn't use CG-NAT on their cable lines. With the server running can you check the port and see if it shows open on one of the port checker sites.

Once the server is running use a site like this:

https://www.yougetsignal.com/tools/open-ports/

and set the port to 25565 and check.

How did you configure the port forward?

 

In your router, you need to forward port 25565 TCP from your WAN IP to your internal IP of the Minecraft server.

It's your public IP address, when you google what's my IPv4 address it should return that address. Are you not using your public IP to access the Minecraft server but a 192.168.x.x address instead?

You have an IP adress on the outside, that's the WAN IP. Because IPv4 addresses are scarce, you don't get an WAN IP for every device on your network.

 

Your router applies NAT, network address translation. The way that works is like this:

 

- Your friends connect to your Minecraft server via your WAN IP. Your router sees the request and forwards it to your Minecraft server

- The Minecraft server accepts the connection and sends back the okay signal via your router, which replies back to your friends.

 

Your friends don't see the internal IP of your server, they only communicate to the NAT host, your router, which does the translation between WAN and LAN, or local and remote IP addresses.

 

Now back to the issue at hand:

 

Once the forward has been made in your router, connect to your WAN IP (from whatsmyip.org for instance) at port 25565. If the forward is setup correctly, it should connect.

In Minecraft, in add server, it'll look like this for instance:

 

69.69.4.20:25565

 

If you try to remote in through 192.x, 172.x. or 10.x. it's usually a local IP range and that is not routable over the internet.

 

If you have more than one router in your network, with different networks (so it's in router mode, not access point or bridge), you have a double NAT and need to forward the port more than once. Once from main router (usually the ISP provided router/modem router) to the secondary router (and from secondary to tertiary etc.) and then from that router to the Minecraft server, assuming that's the one it's connected to.
