Annoyed that I can't game stream because of CGNAT (Perma NAT Type: Moderate)

I, like many other Australians, use 4G Wireless Home Broadband to connect to the internet. Having a moderate NAT has never really gotten in the way of enjoying games, streaming media and various other online activities, until today.

I have Optus 4G internet and Huawei modem. The modem supports UPnP and has its own NAT section of the Security settings area of the web config page. The Xbox is there automatically (as Teredo 192.168.8.132:3074->3074 UDP) confirming that UPnP is working properly.

From the research I've done, and the 45mins of power cycling and fiddling with settings, I can pretty much safely assume I'm on CGNAT 4G internet and there is no way to circumvent this without getting a completely different (and in this area, inferior) wired internet connection.

Why does the Xbox Game Streaming require an Open NAT? I am able to stream games perfectly to my Windows 10 PC without too much hassle, so long as nobody else is using the bandwidth for media streaming... I would have thought the process would have been similar for my Android phone.

Shouldn't there be 2 types of streaming options as well? Local Network and Over the Internet? I could live with not being able to use "over the internet" style because of my NAT type, but that shouldn't matter when the devices are on the same local network, should it?

There was also no warning of this prior to my adventure in setting up Game Streaming.
