<p>Sadly a lot of places imply that Nat provides some form of security when it really wasn't meant for that usage.</p>

If you need a firewall, then you do indeed have to make sure that it's<br>
configured appropriately for both IPv4 and IPv6. There are lazy/uninformed<br>
administrators who think they can rely on NAT as a substitute for a firewall.<br>
<br>
I have native IPv6 access via my ISP and FreeSWITCH works well with it. I have<br>
also used FreeSWITCH over IPv6-in-IPv4 tunnels with surprisingly good<br>
reliability, but in recent years with the native IPv6 this hasn't been<br>
necessary except occasionally with a laptop on an IPv4-only network.<br>
<br>
Deployment in a home office environment was easy enough, except initially for<br>
the DHCPv6 prefix delegation and routing over the ppp connection to the ISP.<br>
