Configuring 4in6 Tunnel Connection 
ZXHN H108N supports supports Dual–stack lite technology.  DS lite technology allows the device 
to encapsulate the IPv4 packets inside IPv6 packets and send the IPv6 packets to the ISP's Carrier 
Grade NAT through its IPv6 WAN connection. The Carrier Grade NAT decapsulates the IPv6 packets, 
and then restores the original IPv4 packet. And then NAT is performed upon the IPv4 packet and is 
routed to the public IPv4 Internet.
