When someone breaks or shuts off that filter, traffic through the NAPT firewall stops working. On the stateful firewall with public IPs on both sides, everything works...including the traffic you didn't want.
People are going to want NAT66...and not providing it may slow down IPv6 adoption.
Hm, if you turn off the NAT66 function, wouldn't the traffic pass through unhindered, too?
Or do you propose to make IPv6 home gateways the same way IPv4 home gateways work, where it's usually not even possible to turn it off?
I think the implication includes available 1918-like space to use behind the NAT which is similarly publicly non-routable; *this* is the part we care about -- that those addresses are only accessible *to the edge router*. Cheers, -- jra
