Disable Teredo on Windows Vista/7

Teredo was designed to deliver IPv6 connectivity to nodes that are located behind IPv6-unaware NAT devices. 
It is enabled by default and creates an encrypted tunnel to Microsoft which all your internet traffic will pass through after the global start of IPv6 which is bound to happen soon as IPv4 address pool is schrinking fast.  

To disable Teredo simply open a command line as an administrator and paste:

At the netsh interface teredo command prompt, type:
set state disabled
