Of course, with IPv4 public addresses on the LAN side, you need a firewall to prevent the server from being completely exposed to the Internet. Firewalls can be implemented at the router or on a separate device.
Yes, IPv6 has Unique Local addressing, but those addresses are intended to be used for housekeeping functions on the local LAN, not for communication with other networks.
NAT-PT is deprecated and will not be used. After a lot of research, it was found that NAT-PT does not do even a mediocre job of protocol translation between IPv4 and IPv6, and will not be used as a transition mechanism.
All IPv6 installations will have publically routable IP addresses with no NAT required. That is the nature of how IPv6 works. All IPv6 hosts are multihomed, so any IPv6 workstation has multiple IPs on it regardless. It will usually have at least one Unique Local, one publically routable obtained from the local router, and possibly more for other purposes like multicast or static assignment. Each address is used for it's intended purpose -- the Unique Local is used for communication with the local router or housekeeping functions like Neighbor Discovery (IPv6's version of ARP), while the publically routable ones are used for communication with other networks. No address translation is ever required for IPv6, nor is it desired.
Where are the public addresses served from? How does it handle the dynamic nature of comsumer networked devices that leave and join your networks (and sometimes other networks)? Is AT&T going to assign a block of 50 static public addresses to each of their subscribers for Lan based DHCP use? Is the public address, that each device is assigned, permannent and/or portable?
