Yeah I am behind CGNAT so I guess I have to use either Tailscale or wireguard as other users also suggested.

Thank you for the reply!

It’s not only not static It’s firewalled too! I can’t ping it from outside the network

tailscale is looking good I might try that

actually I was thinking about hosting my own fediverse service to own my data but I can’t do that without a static public IP and domain name.
