1.8.5 Testing the IPv6-in-IPv4 Tunnel
1 Connect a computer to the USG’s LAN1.
2 Enable IPv6 support on you 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.
3 You should get an IPv6 IP address starting with 2003:1111:1111:1000:.
4 Use the ping -6 [IPv6 IP address] command in a Command Prompt to test whether you can ping
a computer behind USG Y. You should get a response.
1.8.6 What Can Go Wrong?
1 You don’t need to activate the WAN1 IPv6 interface but make sure you enable the WAN1 IPv4
interface. In IPv6-in-IPv4, the USG uses the WAN1 IPv4 interface to forward your 6to4 packets to the
IPv4 network.
2 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.
