Gl spitz x750 port forwarding

Hi I’m trying to port forward on my spitz currently used with a Vodafone sim.

I have setup port forward through the gui and when running nmap it shows the port is still closed no matter what port I do it always says closed I am using duckdns to acces my home assistant

Maybe firewall rules?

How did you scan? You have a public IP on your carrier network? This is generally not possible. Some carriers give you a specific APN to issue you a public IP.

If you want to access your home assistant, you can just try our reverse proxy solution www.astrorelay.com

No public IP and no port forward needed.
