I have been moved to CGNAT

I finally got this this resolved by Ayush, the Telus tech support legend.

He understood private addressing, he understood port forwarding, and he understood it wasn't a dynamic vs static IP issue. I clarified it wasn't a NAT setting my router. That my router does NAT when it receives an IPv4 address from Telus and it leases private addresses to my devices on my network. That's normal. But on top of that, the address my router gets from Telus is "private", in the 100.84.xx.xx range, due to carrier grade NAT. He understood this double NAT stuff. Eventually he came back to me and said that he can disable "CGNAT" and after about twenty minutes later I reset my router and it got a public IP lease.

I asked Ayush if someone else calls in with this issue, what they can say to the support to help them find what setting to change or whatever. He said something like:

"CGNAT to be removed from the main Telus box so once it is removed and refreshed from provisioning it will be a public address."

He said "The right term for this is CGNAT". He spoke the letters "C" "G" "Nat". (The way you would normally pronounce the abbreviation. As opposed to saying "Carrier Grade NAT". Maybe if they search for that in their internal stuff doesn't show anything but "CGNAT" does? I have no idea.)

I'm not sure how much that will help as it seems like their support in general doesn't know how to direct you to someone who knows how to solve your issue.

Maybe the lady from the business support was doing me a favour by not hearing me out and just forwarding me. Maybe in her mind she thought "This guy has problems, we've tortured him enough by bouncing him around to every call center we have. We'll let him through to Ayush."

Good luck to anybody else having to navigate the cosmic horror of Telus's support labyrinth. There is an Ayush out there for all of us if you believe.
