Hi,

Im trying to set up IPV6 to test an IPv6 webserver in a datacentre.
I'm using a Windows 7 computer which is behind an NAT router. The router has a ipv4 public ip from the broadband provider. The Windows 7 PC has a 192.168.1.x address.
Also, the public IP is dynamic.

Ive set up the tunnel on the TunnelBroker website and I used the example configuration to try to set up the Windows 7 pc, however its not working.

I can't ping the IPv6 web server. Ive checked the webserver using an online ipv6 tester and it seems fine.

How do I go about diagnosing this problem?
Thanks
Dan

We're going to need some more information

Are you able to ping your tunnel end point?

Let's see the commands you used to set up your tunnel; also, show the output of ipconfig /all and netstat -a

I tried the following but it failed at line 2 because the local PC has an ip of 192.168.1.30.

1) netsh interface teredo set state disabled
2) netsh interface ipv6 add v6v4tunnel IP6Tunnel 2.27.11.133 216.66.80.26
3) netsh interface ipv6 add address IP6Tunnel 2001:470:1f08:2d2::2
4) netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f08:2d2::1

So I tried the following which didnt show any errors but is clearly wrong.

1) netsh interface teredo set state disabled
2) netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.1.30 216.66.80.26
3) netsh interface ipv6 add address IP6Tunnel 2001:470:1f08:2d2::2
4) netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f08:2d2::1

A few things:

Code Select


1) netsh interface teredo set state disabled
2) netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.1.30 216.66.80.26
3) netsh interface ipv6 add address IP6Tunnel 2001:470:1f08:2d2::2
4) netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f08:2d2::1

This is correct for you because you're behind NAT. To double check, remove your IP6Tunnel adapter, reboot, and recreate using those commands.

If it still doesn't work, your firewall/router is probably blocking protocol41

To clean up ipconfig, run this

Code Select


netsh int ipv6 isatap set state disabled
