Google with Android 6, while not making quite the commitment Apple has made, will support NAT64 (and IPv6-only) networks if the app supports it (alas there are still too many apps which are v4-only). Upon roaming the ASA FQDN address is re-resolved to IPv6 or IPv4 respectively. We show how to setup the Cisco router IOS to create Crypto IPSec tunnels, group and user authentication, plus the necessary NAT access lists to ensurn Split tunneling is properly applied so that the VPN client traffic is not NATted. Some of these devices do not support IPv6 at all, so the migration process is necessary since IPv4 and IPv6 will likely coexist for some time.
