Having deployed IPv6 at the internet point and halfway into the company =
I work for I can tell you that I am *really* glad that I can now see =
what a firewall rule does properly instead of also having to peer at the =
NAT table which is 1:1 or a port forward etc. Also, when IPv4 NAT and =
rules don=92t match up, hilarity ensues.

It greatly improves my workflow, it=92s just become a whole lot easier =
for me.

NAT66 definitely has a place, and I=92m a huge proponent for it so the =
small SMB people and home users so they can do Multi Wan without BGP. =
The part that isn=92t solved yet by the IETF, but at least there is a =
really good RFC for NPt.

In my experience it improves security because of the transparency.

For anything resembling > 100 people, get a ASN, PI and BGP. You=92ll =
thank me later, unlikely to have to renumber anything(1).

Kind regards,

Seth

(1) Yeah I know, unless you grow from a /48 to a /32
