  • How do I enable Teredo tunneling to the default Microsoft server mentioned in the Wikipedia article (teredo.ipv6.microsoft.com)? Google did not find any documentation, reliable or otherwise, to do so.
  • Additionally, is it possible to share the IPv6 connectivity from the tunnel to be shared?

I am looking to do the above on both Windows 7/8 and Ubuntu.

Teredo tunnels are very unreliable, are only used when connecting explicitly to an IPv6 address, and they give you only one IPv6 address per client so you can't share them. If you want IPv6 then use a decent tunnel server like sixxs.net or tunnelbroker.net, and stay far away from Teredo and 6to4.

Can we not do an IPv6 NAT? And it's a one-time thing, so I don't want to bother registering for those services. –  Oxwivi Apr 18 '13 at 7:37
    
Technically you can do NAT with IPv6, but the biggest problem is Teredo. It is so unreliable that even Microsoft gives it a very low preference compared to other tunnel mechanisms. Take a look at tools.ietf.org/html/draft-steffann-tunnels-03 for more information. Setting up a tunnelbroker.net tunnel will be much faster and easier than messing with Teredo and NAT. –  Sander Steffann Apr 18 '13 at 9:11
