4.4.14 IP Tunnel

IPv6 tunnel is a kind of transition mechanism to enable IPv6-only hosts to reach IPv4 services and

to allow isolated IPv6 hosts and networks to reach each-other over IPv4-only infrastructure before

IPv6 completely supplants IPv4. It is a temporary solution for networks that do not support native

dual-stack, where both IPv6 and IPv4 run independently.

Choose “Advanced Setup”“IP Tunnel”, it includes two menus: IPv6inIPV4 and IPv4inIPv6,

The detailed descriptions are provided below.
