and the practice in Germany to blocking all IPv6-inbound traffic the result is the problem for some gamers.
So I guess applications should use the same technique as one does to traverse NAT44:s, ie both ends of the connection send packets to each other to open their respective firewall.
I do agree that the firewall in question needs to not send rejects for this traffic for this to work. I am happy this use-case was brought up, because I hadn't heard and thought about this before. Personally I don't want to silently drop packets, so I guess clients need to try a few times and not listen to the (initial) ICMP messages until the "hole" is open.
