That's how the settings were worded on my old Google OnHubs.  It was port "port forwarding" for IPv4 and "port opening" for IPv6.  Everything unsolicited for incoming IPv6 is blocked unless you "opened" the port.

I agree!  There are no firewall rules to be found on this interface and any "port forwarding" or "port triggering" settings are for IPv4 only.  It would appear that the router is blocking all unsolicited incoming IPv6 traffic, which is actually a good thing, but I'm surprised there's no way to allow certain ports on this router yet.
