SCENARIO DESCRIPTION:

How to Set Up IPv6 Interfaces for Pure IPv6 Routing      

This example shows how to configure your ZyWALL/USG WAN and LAN interfaces which connects two IPv6 networks. ZyWALL/USG periodically advertises a network prefix of 2002:1111:1111:1111::/64 to the LAN through router advertisements.    

ZyWALL/USG with Pure IPv6 Network Example

 

 

 

 

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).

 

 


SETUP/STEP BY STEP PROCEDURE:

Enable the IPv6 on the ZyWALL/USG

  1. In the ZyWALL/USG, go to CONFIGURATION > System > IPv6 > Global Setting, select the Enable IPv6 and click Apply at the bottom of the screen.

CONFIGURATION > System > IPv6 > Global Setting

Set Up the WAN IPv6 Interface on the ZyWALL/USG

  1. In the ZyWALL/USG, go to CONFIGURATION > Network > Interface > Ethernet > wan1. Select Enable Interface and Enable IPv6. Select Enable Stateless Address Auto-configuration (SLAAC). Click OK.

CONFIGURATION > Network > Interface > Ethernet > wan1

Note: Your ISP or uplink router should enable router advertisement.

 

Set Up the LAN IPv6 Interface on the ZyWALL/USG

  1. In the ZyWALL/USG, go to CONFIGURATION > Network > Interface > Ethernet > lan1. Select Enable Interface and Enable IPv6. Select Enable Stateless Address Auto-configuration (SLAAC). Select Enable Router Advertisement and click Add to configure a network prefix for the LAN1 (2002:1111:1111:1111::/64 in this example). Click OK.

CONFIGURATION > Network > Interface > Ethernet > lan1 > General Settings

CONFIGURATION > Network > Interface > Ethernet > lan1 > IPv6 Router Advertisement Setting


VERIFICATION:

Test the Result

  1. Connect a computer to the ZyWALL/USG’s LAN1.

 

  1. Enable IPv6 support on your computer. In Windows XP, you need to use the IPv6 install command in a Command Prompt. In Windows 7, IPv6 is supported by default. You can enable IPv6 in the Control Panel > Network and Sharing Center > Local Area Connection screen

 

  1. Your computer should get an IPv6 IP address (starting with 2002:1111:1111:1111: for this example) from the ZyWALL/USG.

Window 7 > cmd > ipconfig

 

  1. Open a web browser and type http://test-ipv6.com/. You can see the IPv6 connectivity result shown as below:

 

What Can Go Wrong?

 

  1. If your IPv6 connection is not working, please make sure you enable Auto-Configuration on the WAN1 IPv6 interface. If not, you will not have any default route to forward the LAN’s IPv6 packets.

 

  1. In Windows, some IPv6 related tunnels may be enabled by default such as Teredo and 6to4 tunnels. It may cause your computer to handle IPv6 packets in an unexpected way. It is recommended to disable those tunnels on your computer.
