Have you reached out to your ISP to see if they can give you a dynamic public IP? I recently swapped to a new ISP that was using CGNAT but after contacting their support team with my use case, they were happy to set me up with a public IP so I could continue my self-hosting.
This. I had the same situation being put behind CGnat and told them my security webcam needs port forwarding from outside and they had me back to a public IP within minutes.
ISPs in Canada usually include a clause in their TOS that explicitly prohibits selfhosting. Don't move here, it sucks.
🫤 that does suck. Probably so they can charge more for a hosted package?
It's to push users into getting commercial accounts.
I dunno. The IPv4 address space is getting pretty tight, and aside from rejiggering existing inefficient allocations, there's not a lot you can do beyond NAT.
In the US, we had it pretty good for a long time, because we had a rather disproportionate chunk of the IPv4 address space -- Ford, MIT, and Apple alone each had their own Class A netblock, about half a percent of the IPv4 address space each, for example.
But things have steadily gotten tighter as more and more of the world uses the Internet more and more.

Like, there's real scarcity of the resource. It doesn't require the scarcity to be artificially-induced.
My ISP used to let one get a /29 IPv4 block for residential users, though they stopped that years ago. Always have had a way to get publicly-facing IPv6 addresses, though.
End of the day, the real fix is to get the world on IPv6.
Not even offered in my area 🤡
I don't know Canada laws but does it only apply if you make money off it (or intend to). Self hosting Jellyfin server is basically just delayed uploading.
Afaik it's at the ISP's digression. Up until I switched, Bell would block ports 21, 22, 53, 80 and 443.
That's pretty nice compromise. 80 and 443 are the ones mainly used commercially
It's kinda shitty of them to block the ports that makes up +30 years of what the internet IS. Bell/Rogers want your internet connection to be unidirectional, when you host your own content you don't consume theirs.
Yeah, not arguing that, it doesn't cost them extra to allow those. Still, you can use 8080, 8989, 5000, 7878 etc, for plex, Jellyfin, nextcloud and so on.
You can even workaround it by using cloudflare functions that forward requests to your specific port, DNS it to cloudflare and run a commercial webapp out of your garage anyway.*
*Except if you want to honor whatever ToS they had you agree to.
