aspect worth noting: up to my knowledge HE's tunnel will work only if you're assigned public IPv4 by your ISP. if you're behind a carrier grade NAT - too bad, you'll need to use another solution to get IPv6 to your home.

Strange. This sounds like something Hurricane Electric specifically limited. There’s nothing in CGNAT that would naturally break such a tunnel

[pQd]

HE is using plain stateless IPv6 in IPv4 tunnel - it's neither TCP nor UDP, it's not NAT'able.

it's relatively simple for them to implement [ the stateless part ] but due to that puts some requirements on the party establishing the tunnel.

I use tunnels all day like this with cgnat on multiple devices.

Go Fiber (Shentel) is one such ISP, and they will gladly switch you to a public IP for no cost if you contact their support. Sadly they don’t support IPv6 yet.
