Port Forwarding for a minecraft server problems

[MrP6k]

I'm using a HG8245H5 router, this is what i have set on the router's webpage, but then i used a website to check if the port's open, it shows that it's closed.

the server was running when checking the port.

yes, the server is running on the port 25565

does anyone have any idea what i could've done wrong?

yes, i have added new rules to windows firewall on both inbound and outbound, tcp and udp

I've been spamming the "check port" button on the website, sometimes the port's closed, other times it's open. any idea what's wrong here?

Have you clicked on the button which says "Add"?

i spammed the check port button, it said "port open" for 3 times, then changed to "port closed"

Also you aren't behind a carrier-grade NAT are you? Because if that's the case you will need to talk to your ISP and get a static IP address.

Hard for us to tell.

Call your ISP.

What ip are you using in the server properties file?

If your WAN IP address falls between 100.64.0.0 to 100.27.255.255 or starts with 192.168 or 10 then you're on carrier grade NAT.

I'm sorry but I don't understand what that means and how i check for it

[MrP6k]

also, i tried hosting the server on my neighbours wifi and it worked flawlessly! we use the same ISP, but they have a 

MediaAccess TG389ac High Power router, while i have the HG8245H5

would that have an effect on it?

if WAN ip address means public ip address, then no. my public ip starts with a 158.

You need to put your local ip in the Server.ip field. Once it's started you can check the ports again

If your public IP starts with 10 then yes, that would be carrier grade NAT.

is there any other solutions to this? or do i just have to get a static ip address?

There is a way using a VPN, though Im not sure how the config works on that. If your ISP offers a public IP address then that would also be a route. Just keep in mind that a Static IP or just a public IP might not be available. The reason Carrier Grade NAT exists is because we have exhausted most of the Internet routable IPv4 addresses. I know in some areas of the world Carrier Grade NAT has become standard. If anything be prepared to pay more. Static IP's tend to cost more money, a VPN will cost money. You might even think about renting a VPS and having them host the Minecraft server for you depending on the costs.
