Set Up the LAN IPv6 Interface on the ZyWALL/USG
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.
In the ZyWALL/USG, go to CONFIGURATION > Network > Interface > Ethernet > lan1,
Select Enable Interface and Enable IPv6. Type 2002:7a64:dcee:1::111/128 in the
IPv6 Address/Prefix Length field for the LAN1’s IP address.
Enable Router Advertisement. Then click Add in the Advertised Prefix Table to add
2002:7a64:dcee:1::/64. The LAN1 hosts will get the network prefix through the router
advertisement messages sent by the LAN1 IPv6 interface periodically. Click OK.
