On: The IPv6 Transition

[saurik]

Have you tried using PCP to forward the port? I was under the (maybe-incorrect, and if so I would really like to learn) impression that most major CG-NAT setups supported it.

Nah, many carriers don’t support it. I’ve always had to resort to STUN

[matrix2003 → kortilla]

STUN also isn’t guaranteed if the router is strict. IPv6 removes a lot of these unknown and strange ways that IPv4 infrastructure can break things.

[orangeboats → saurik]

PCP is not widely deployed in South East Asia at the very least. Relying on it is not feasible.

I suppose I can try that some time. I can find absolutely zero mentions of that for the ISP, just the option of buying a static IP.
