LAN > IPv4/IPv6 Dual Stack
The router supports IPv4/IPv6 dual stack by default, it means IPv4 packages route to IPv4
network and IPv6 route to IPv6 network.
Since IPv6 is global IP, there is no NAT between WAN site and LAN site. One device only needs
one global IPv6. There is IPv6 firewall protection in the router by default. Only the IPv6 packages
come from LAN site device and got reply back.
