Proj Win-4: Teredo Client on Windows 7 (10 pts.)

Purpose

This is a simple way to get IPv6 connectivity on a Windows 7 computer, using the Teredo protocol which can connect through the type of NAT used on home routers.

It does that by putting the IPv6 packets inside UDP packets transported over IPv4.

Open an Administrator Command Prompt

Click Start. Type in CMD and press Shift+Ctrl+Enter. If a "User Account Control" box pops up, click Yes.

Resetting the Network Stack

On your Windows 7 machine, in case some previous project has messed things up, execute these commands:
netsh winsock reset catalog

netsh int ipv4 reset reset.log

netsh int ipv6 reset reset.log

Restart the Windows 7 machine.

Disconnecting the gogoCLIENT

If you have the gogoCLIENT installed, launch it and disconnect it, as shown below:

Connecting via Teredo

On your Windows 7 machine, in an Administrator Command Prompt, execute these commands:
netsh interface teredo set state client teredo.remlab.net 10 3545

netsh interface teredo show state

If your Teredo state is "dormant", as shown below, you need to send some IPv6 pings to wake it up.

On your Windows 7 machine, in an Administrator Command Prompt, execute this command:

ping -6 google.com
You may see some replies, as shown below:
