I have a route to his dsl router, which, assuming that the ipv4 and ipv6 firewalls are as good at allowing/disallowing access, makes his current ipv4 and his future ipv6 addresses equally accessible.

I've been following the NAT debate here and something occurred to me.

If you have an IPv4 network with NAT, an attacker doesn't need to know your internal IPs. All he needs is the IP to your router. NAT will nicely forward his packets along to whichever internal computer handles the port.

What port/computer would that be? Most consumer routers default to not forwarding anything that is not related to prior outbound activity.
