Internet Port IP Address not matching real Internet IP Address

Your ISP appears to deploy CGN, Carrier Grade NAT (RFC6598: IANA-Reserved IPv4 Prefix for Shared Address Space) to overcome the shortage of public IPv4 addresses.
The NBN does only make up the transport layer, anything above is under the ISP responsibility.
Talk to your ISP, requesting a public routeable IPv4 address on your connection.

Thanks so much for a speedy reply. I will check it out. Could this be the root of all my port forwarding issues as well?
Yes, of course. We have no control about the port forwarding on the ISP' CGN routers.

As a concluding note: Yes, this was the issue. And for 6 months, I've thought about throwing out my (brand new) Orbi routers because I couldn't get port forwarding to work.
Thanks for the assistance - saved me quite a bit of money. Was able to opt out of the CGNAT by giving my valid reasons for needing a real IP address :)
