Configuring the IPv6 Teredo Tunnelling client in XP

[pctech]

Important note

This should not be used for latency sensitive apps as in my experience it vastly increases latency because of the tunnelling effect,

First you need a free access Teredo server, have a look here http://www.ipv6day.org/action.php?n=En.GetConnected-Teredo (I'm not aware of any UK ISPs that are currently running a Teredo server)



Go to Start > Run
Type cmdand click OK
At the command prompt type netsh and press enter
At the netsh prompt type set teredo client <server address or IPv4 IP> and press enter
Windows should respond with ok.
Type commit and press enter
Type exit and press enter.
Close the command prompt.

Open a browser and enter into the address bar ipv6.google.com (if it works you have configured Teredo correctly and you can now browse pages and use resources irrespective of whether the server has an IPv4 or IPv6 address.

Thanks for that, Mitch, very useful for all us dinosaurs. I'm going to sticky this.

Latency on resolution seems to have disappeared but I was streaming audio over the web when I was writing that so probably had something to do with it

Description of teredo tunnel (or 6 to 4)

http://technet.microsoft.com/en-us/library/bb457011.aspx

Abstract
Teredo is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 traffic when IPv6/IPv4 hosts are located behind one or multiple IPv4 network address translators (NATs). To traverse IPv4 NATs, IPv6 packets are sent as IPv4-based User Datagram Protocol (UDP) messages. This article provides an overview of Teredo—including Teredo addresses and packet structures—and detailed explanations of how communication is initiated between Teredo clients, Teredo host-specific relays, and IPv6-only hosts using the IPv4 Internet, the IPv6 Internet, Teredo servers, and Teredo relays.

I'm glad it's not just me. 

[Rik]

You're never alone with a Teredo Tunnel.

[Steve]

I'm none the wiser either

[Rik]

I feel better now.

[Steve]

More here http://www.nedprod.com/Niall_stuff/addingIPv6toyourhome.html and also here http://www.tunnelbroker.net/ which if I understand is your IPv6 enabled host (desktop) going through your IPv4 NAT as a teredo tunnel to a IPv6 router on the internet.

[pctech]

Just set it and forget it, once ISPs start handing out IPv6 addresses and doing the name resolution which is effectively what those servers are doing you won't have to think about it.

[Rik]

I do hope so.

[Steve]

Once ISPs start handing out IPv6 addresses we won't need a torredo tunnel will we?

[pctech]

Definitely not.

Only ISP I know to be doing that as an option at the minute is AAISP and Zen of reconfiguring their network.

[Rik]

But IDNet is IPv6 ready.

[pctech]

I did not know that.

[Rik]

It's not been trumpeted, Mitch, but they are.

[pctech]

If the nameservers are resolving requests for IPv6 requests then it may not be necessary.

[Steve]

The consumer hardware is very limited at present if this page is anything to go by.

[Rik]

That's slightly worrying, Steve, it suggests some very rapid development come the day, and a lot of flawed firmware.

[pctech]

No doubt.

[DorsetBoy]

Definitely not.

Goscomb are running IPv6.......... ( I know, I had never heard of them till the other day.)

[pctech]

I've heard of them but didn't know that.
