and both are supported. Additional EUI-64 IPv6 addresses of network interfaces are generated
automatically by standard methods. There is a NAT64 internal gateway network interface for
automatic translation between IPv6 and IPv4 (see Chapter 3.5 for more information). This
gateway works together with DNS64 seamlessly (for domain names translation).
For cellular IPv6 connection see Mobile WAN Configuration in Chapter 4.3.1. For IPv6 L AN
configuration see LAN Configuration in Chapter 4.1, DHCPv6 server/client is also supported.
IPv4 is the default, but IPv6 can be enabled or used with all features and protocols in the router,
except for non-secured tunnels GRE, L2TP and PPTP, and VRRP. Using the secured tunnels
OpenVPN and IPsec it is possible to run IPv6 traffic through an IPv4 tunnel and vice versa.
The configuration forms for NAT, Firewall and Up/Down Scripts are completely separate for
the IPv4 and IPv6 stacks. ICMPv6 protocol is also supported. IPv6 configuration is covered in
each following Chapter when possible.
