If you need a firewall, then you do indeed have to make sure that it's
configured appropriately for both IPv4 and IPv6. There are lazy/uninformed
administrators who think they can rely on NAT as a substitute for a firewall.

I have native IPv6 access via my ISP and FreeSWITCH works well with it. I have
also used FreeSWITCH over IPv6-in-IPv4 tunnels with surprisingly good
reliability, but in recent years with the native IPv6 this hasn't been
necessary except occasionally with a laptop on an IPv4-only network.

Deployment in a home office environment was easy enough, except initially for
the DHCPv6 prefix delegation and routing over the ppp connection to the ISP.
