6.2 How to Set Up an IPv6 6to4 Tunnel
This example shows how to configure your ZyWALL/USG to create IPv6 6to4 Tunnel. In this
example, the ZyWALL/USG acts as a 6to4 router which connects the IPv4. After configuration, the
ZyWALL/USG can assign an IPv6 to clients behind it and pass IPv6 traffic through IPv4 environment
to access remote IPv6 network.

Note: All network IP addresses and subnet masks are used as examples in this article.
Please replace them with your actual network IP addresses and subnet masks. This
example was tested using USG310 (Firmware Version: ZLD 4.13).
6.2.1 Set Up the LAN IPv6 Interface on the ZyWALL/USG
1 The second and third sets of 16-bit IP address from the left must be converted from wan1 IP
(122.100.220.238 in this example). It becomes 7a64:dcee in hexadecimal. (You can go to https://
isc.sans.edu/tools/ipv6.html#form to convert an IPv4 address into it's default 6-to-4 equivalent).
You are free to use the fourth set of 16-bit IP address from the left in order to allocate different
network addresses (prefixes) to IPv6 interfaces. In this example, the LAN1 network address is
assigned to use 2002:7a64:dcee:1::/64 and the LAN1 IP address is set to 2002:7a64:dcee:1::111/
128.
