IP Transition Demonstration Teredo Windows

This video will look at how to configure Teredo on Windows. If your Windows computer does not have a native IPv6 connection, Teredo can be configured, which will allow Windows to access the IPv6 network using its IPv4 connection.

This is because Teredo works differently if it is configured on a computer that is in a domain and a computer that is standalone. In this video, a domain computer that is on a home network will be configured. This will demonstrate all the problems that you may encounter configuring Teredo on your network. In this example, the home network will only have IPv4 support and thus a transition protocol will be required in order to access the IPv6 internet. Demonstration 00:58 Teredo has been available in Windows since Windows XP. The procedure for enabling it or disabling is the same regardless of which version of windows you are using. On the client version of Windows after Windows Vista it is enabled by default. Before Windows Vista, Teredo was disabled and had to be enabled. Currently, in Windows 10 it is enabled by default, however, as the internet becomes more IPv6 ready, in future versions of windows it may be disabled by default. In the case of Windows Server, Teredo is disabled by default. 01:16 To view the current network configuration, right click on the start menu and select the option “Network Connections”. 01:27 To see the network connection of a network adapter, right click the adapter and select Properties. In this example there is only one network adapter which is Network 2. 01:35 Scrolling through the protocol list, “Internet Protocol Version 6 (TCP/IPv6)” is ticked. In order for Teredo to work, IPv6 needs to be ticked and thus enabled. Also “Internet Protocol Version 4 (TCP/IPV4)” needs to be ticked. Other protocols like ISATAP do not require the IPv6 protocol, however as we will see later in the video, Teredo requires the IPv6 protocol in order to operate. 01:51 To see the properties of IPv6, make sure the “Internet Protocol Version 6 (TCP/IPv6)” is ticked and press the Properties button. 01:55 By default, IPv6 will be configured to “Obtain an IPv6 address automatically” and “Obtain DNS server address automatically”. If IPv6 becomes available, the administrator may decide to configure a static IPv6 address. If this is to occur, Teredo will automatically be disabled. The same will occur if the computer obtains an IPv6 address via DHCP or through Stateless Auto Configuration. Essentially Teredo is designed to be used when no IPv6 network is available, thus if the device is configured with a valid IPv6 address then Teredo is disabled as it is no longer required. 02:27 To configure Teredo, right click the start menu and select “Command Prompt”. If there are any open windows from the previous step, close these windows before opening the command prompt. 02:37 To show the current configuration of the computer, run the command “IPConfig”. 02:45 In the output of IPConfig, most likely at the bottom, is a section called “Tunnel adapter Teredo Tunneling Pseudo-Interface”. This section contains the configuration for Teredo. This will show the current IP Address being used by Teredo, Link-local address and gateway. If Teredo has not been configured “Media State” will be shown as “Media Disconnected”. If the computer is configured with an IPv6 address, Teredo will automatically be disabled and thus may not appear. 03:08 In Windows 10, Teredo is enabled by default and an IPv6 address will be shown. This IPv6 address contains the Teredo server IPv4 address, Teredo Client IPv4 address and other Teredo configuration options. Later in the video the Teredo address will be looked at in more detail. 03:25 To test the Teredo connection, run the command “Ping -6 google.com” or another address of your choosing. In this case, Teredo is enabled, however, the command returns “Destination host unreachable”. Teredo is configured by default, however, the default configuration points to a Microsoft Teredo server that is no longer in use.
