Since firmware version 3.00, the ZyWALL supports IPv6 configuration in these Ethernet, PPP,
VLAN, Bridge and Policy Route screens under Configuration > Network > Interface and
Configuration > Network > Routing. Basically, these are the same as the ones for IPv4
networks except the following differences:
• You have to enable IPv6 globally in the CONFIGURATION > System > IPv6 screen to make the
IPv6 settings work.
• An Enable IPv6 setting - Select this in the screens listed above to enable the ZyWALL to be able to
send and receive IPv6 packets through the interface. Otherwise, the ZyWALL discards IPv6 packets
flowing through the interface.
• IPv6 Address Assignment - This section allows you to enable auto-configuration and configure
prefix delegation.
• DHCPv6 Setting - This section allows you to configure the DHCPv6 role and the corresponding
settings for the interface.

1.6 How to Set Up IPv6 Interfaces For Pure IPv6 Routing

This example shows how to configure your ZyWALL Z's WAN and LAN interfaces which connects two
IPv6 networks. ZyWALL Z periodically advertises a network prefix of 2006:1111:1111:1111::/64 to
the LAN through router advertisements.
Note: Instead of using router advertisement, you can use DHCPv6 to pass the network
settings to the computers on the LAN.

DESCRIPTION
Configure this if any interface on the ZyWALL is connecting to an Ethernet network. Ethernet
interfaces are the foundation for defining other interfaces and network policies.
Configure this if you need your service provider to provide an IP address through PPPoE or PPTP in
order to access the Internet or another network.
Configure this if you want to divide your physical networks into multiple VLANs, or your service
provider or an aggregated network needs the ZyWALL to recognize the VLAN tags in the packets
flowing through the ZyWALL.
Configure this if you want the ZyWALL to combine two or multiple network segments into one
single network. Although the ZyWALL is "transparent" in this mode, you can still apply security
checking on packets flowing through the ZyWALL.
Configure this if you want to override the ZyWALL's default routing behavior in order to send
packets through the appropriate interface or VPN tunnel.
