Dual Stack Lite
Use Dual Stack Lite when local network computers use IPv4 and the ISP has an IPv6 network. When the
VMG has an IPv6 WAN address and you set IPv4/IPv6 Mode to IPv6 Only, you can enable Dual Stack Lite
to use IPv4 computers and services.
The VMG tunnels IPv4 packets inside IPv6 encapsulation packets to the ISP's Address Family Transition
Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also use IPv6 services.
The VMG uses it's configured IPv6 WAN IP to route IPv6 traffic to the IPv6 Internet.
