This doesn&#x27;t sound right to me. There is no need to do address translation in IPv6 networks. It may be that there is still a firewall in place with rules about incoming and outgoing connections, though.<p>In the IPv4 realm the term NAT is often interpreted to mean connection rules in addition to network address translation. It is the address translation that is the source and focus of much criticism of IPv4 &quot;NAT&quot; and it is exactly that feature that is unneeded in the IPv6 realm.<p>So while network address translation is superfluous in IPv6, there is still an argument to be made for network access rules.<p>I would be interested to here what technical arguments were being made for true network address translation in an IPv6 network.
