Nokia 5G Modem have feature for port forwarding but when I add my ports and forwarding device it does not work and I cannot connect to that port from outside of my network. How can I get NAT to work on my Nokia 5G Modem.
I don't need static IP Address. As long as I can forward port to dynamic IP Address. No Reply from optus yet. They keep saying that this is wireless service and its how this is setup. I guess Optus need to lift the game here.

The problem is the CGNAT (which virtually all mobile and wireless services use) will give your service a dynamic IP address which is PUBLIC, but is SHARED with multiple other services. The IP address that your modem gets (dynamic or otherwise) is a PRIVATE IP address.
Because your public IP address is shared, port forwarding will not work for remotely initiated connections.
