I have been moved to CGNAT

I'm having the same issue since yesterday. I spent 130 minutes on the phone with Telus support, I spoke with three folks from "loyalty" who shuffled me between three different tech support representatives. Nobody knew understood IP addressing or knew what CGNAT or DHCP was so it was impossible to explain the issue and how to resolve it. They kept telling me; they weren't trained on this, there was no information about it in their knowledge-base, nobody in their department can help me, and there is no person or department to escalate it to. It's wild to me that nobody in Telus's support staff know what NAT is.

What worked best was explaining that if I have a server, like a website or I'm hosting a video game to play with friends, they cannot connect to me because I don't have a public IP address for them to connect to that routes to my router.

They still weren't able to help me. But after spending an hour trying to explain NAT to three different support representatives, I found the above to be the most succinct "prompt" that convey the issue I was having.

I'm also on the 250 Fibre plan in BC. And I'm using the funny Nokia media converter thingy that it sounds like OP is using. I've had this equipment for like seven years and this is the first time Telus has put me on CGNAT.

I expected some resistance from them about how a public IP isn't guaranteed as part of the plan. I expected I'd just explain to them that the only reason I'm with Telus is because of Fiber and, if I'm behind NAT, all the benefits are lost so I'd have no reason to use Telus. It's incredibly straightforward. I had no idea that after being on the phone for more than two hours across six agents I wouldn't speak with a single human being who understood the issue or could do anything about it.
