12. 5. Set Up the IPv6 Tunnel
The IPv6 Tunnel feature helps you obtain IPv6 resources based on an IPv4 WAN
connection or vice versa.
IPv6 Tunnel is a transition mechanism that enables IPv6-only hosts to reach IPv4
services or vice versa and allows 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.
The router provides three tunneling mechanisms: 6to4, 6rd, and DS-Lite. The methods
of setting up 6rd and DS-Lite tunnel are similar.
12. 5. 1. Use the Public IPv6 Tunnel Service-6to4
The 6to4 tunnel is a kind of public service. If there are any 6to4 servers on your network,
you can use this mechanism to access IPv6 service. If your ISP provides you with an
In the example, the IP address of the company network is the
destination IP address, so here we enter 172.30.30.1.

Subnet Mask:
Determines the destination network with the
destination IP address. If the destination is a single IP address,
enter 255.255.255.255; otherwise, enter the subnet mask of
the corresponding network IP. In the example, the destination
network is a single IP, so here enters 255.255.255.255.
•
Gateway:
The IP address of the gateway device to which the
data packets will be sent. This IP address must be on the
same subnet with the router's IP which sends out the data. In
the example, the data packets will be sent to the LAN port of
Router B and then to the Server, so the default gateway should
be 192.168.0.2.
•
Interface:
Determined by the port (WAN/LAN) that sends
out the data packets. In the example, the data is sent to the
gateway through the LAN port of Router A, so
selected.
