Hi!

I’m using KPN Box 12 and I want to set up port forwarding for my application.

However, it’s not working, as I used tool such as canyouseeme.org to check the port and it shows that the port is closed.

Below shows my configuration for port forwarding.

In External host, I filled in the public IP of my router.

In Internal host, I filled in the local IP of the device where my application runs.

In Internal Port, I filled in the port of the local device where the application is listening to.

I have shut down the firewall, and I can successfully ping my device through other device in the same local network.

Please help me with this issue.

My Dutch is poor, please kindly use English.

Thanks in advance for the response.
