Glad to hear that you don't have a problem with your router, but how does that relate to GPs problems with theirs?

It isn't. But It's also not an answer to GP.

The solution for them is "get a better router" because the problem is not the IPv6 protocol. Opening a port is not harder than creating a NAT forwarding and if your hardware can't do it then it's bad.

		Exactly, and “there are a lot of bad v6 implementation CPEs out there” is an important data point worth acknowledging.
