I have created a local node server on my laptop. And I can access it using the private IP (like 192.168.1.9:8080) on same network on my other devices like phone and other PC. I have disabled firewall.

But now I want to access it using my public IP. So that anyone using a different Internet connection can also connect to it. But it just doesn't respond.

I added a DMZ Host:

Then I added this port forwarding setting (I saw it on YouTube tutorial). I'm not very sure if it's correct or not.

And here is network status:

But it made no difference. Am I doing something wrong?

Note: My problem is probably not related to Hairpin NAT.

PS: If you think I've shared some sensitive/private information in the screenshots, please let me know I'll update it immediately.

first check if your ISP doesn't user GCNAT and provides you with a real IP address. then you need to configure a firewall and port forwarding your router. Don't do all port range from 1 to 65535, configure only ports you need.

yourrounter_IP:8080 => localserver_IP:8080
