Problem setting up tunnel with Windows 7 64-bit

[Insano]

Hello,

First of all I want to note that I read through all the threads about the same problem (http://www.tunnelbroker.net/forums/index.php?topic=653.0), but I didn't find the solution to my problem.

I'm trying to set up a tunnel, which I've already requested. So I have the tunnel details, but the config commands for Vista/2008 don't seem to work. This is what I'm given:

Code Select Expand

netsh interface ipv6 add v6v4tunnel IP6Tunnel 193.190.253.144 216.66.84.46
netsh interface ipv6 add address IP6Tunnel 2001:470:1f14:762::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f14:762::1

The first time entering these commands (as Administrator of course) I received no error, but I couldn't reach ipv6.google.com. So I reseted the ipv6 ("netsh int ipv6 reset"), but when I now try to enter the commands again I get the following error: "You were not connected because a duplicate name exists on the network. If joining a domain, go to System in Control Panel to change the computer name and try again. If joining a workgroup, choose another workgroup name." for the first command and "The object already exists." for the second and third.

Here is my "ipconfig /all" and "netstar -nr" information:

Thanks in advance for your help!

Are you behind a NAT?

[Insano]

I think I am, but I'm not 100% sure. I'm on a university network where everybody shares the same IP to the outside world.

Is there a way to check this out for sure? And does this affect the way I should set up the tunnel?

My fault..I should have read the output you supplied a little closer.  Your IP address is a 10., meaning you are on a NAT.

This would explain why you were unable to get your tunnel to work.

You had posted a copy of the output of your system...was it before or after you ran "netsh int ipv6 reset" ?

[broquea]

64-bit also requires that "interface=IP6Tunnel" bit to be used

[Insano]

The given output was from after I ran the "netsh int ipv6 reset" command, and is the current state I'm in.

64-bit also requires that "interface=IP6Tunnel" bit to be used

Does this mean that the command

"netsh interface ipv6 add v6v4tunnel IP6Tunnel 193.190.253.144 216.66.84.46"

should change into

"netsh interface=IP6Tunnel ipv6 add v6v4tunnel IP6Tunnel 193.190.253.144 216.66.84.46"?

This gives the error message "The following command was not found: (...)", so I assume that's not the part that I have to change.

[broquea]

It means:

netsh interface ipv6 add v6v4tunnel interface=IP6Tunnel $ipv4b $ipv4a

Like in the example for Windows Vista/2008/7 in this forum thread

[Insano]

I see. I still get the two errors I described in my first post though when I try to execute the commands.

Two questions remain:

• Do I first have to remove all the commands I've entered before?
  
• Do I have to alter the commands to match a different IP than the one the outside world sees?

Thanks for the help so far, by the way!

[broquea]

There is some netsh ipv6 reset command, it's somewhere in all these Windows threads. I don't remember the command off hand.

You should be using the 10. address instead of the ipv4 endpoint, like the *NOTE* recommends when generating the example commands in the broker's webUI.

[cholzhauer]

Just a reminder/FYI...  Are you sure that the firewall you're behind is passing protocol41 traffic?

Okay, so I subsituted the 10. address (10.8.18.242) for my previous ipv4 endpoint address (193.190.253.14).

I entered the following command:

netsh interface ipv6 add v6v4tunnel interface=IP6Tunnel 10.8.18.242 216.66.84.46

But I get once again the same error: "You were not connected because a duplicate name exists on the network. If joining a domain, go to System in Control Panel to change the computer name and try again. If joining a workgroup, choose another workgroup name."

Just a reminder/FYI...  Are you sure that the firewall you're behind is passing protocol41 traffic?

I have no idea whether this is the case. As you by now must have noticed, I'm new to this and still trying to figure a lot of this out.

If I had to guess, I'd say that the firewall of my router isn't blocking protocol41 traffic, because I could set up a proper tunnel with Hexago on Windows Vista.

[cholzhauer]

I think I am, but I'm not 100% sure. I'm on a university network where everybody shares the same IP to the outside world.

If I had to guess, I would say proto/41 is being blocked "just because"

Hexago/Go6/GoGo6 does not use Proto/41..IIRC they tunnel over TCP.

As for your error, take a look at reply number 14 from jimb
http://www.tunnelbroker.net/forums/index.php?topic=780.0

[Insano]

That post of jimb helped me avoid the errors. I now have the connection set up, but its state is disconnected.

Here is the code of the command inputs and the interface state at the end.

Have you tried pinging something like ipv6.google.com?

Most firewalls/NAT devices won't allow proto-41 traffic in unless something inside generates outbound proto-41 traffic.  Therefore the status will be 'disconnected' until some traffic is generated.

What are you using for your network firewall/NAT?  If possible configure a protocol forward NAT entry on this device, forwarding any IP protocol 41 traffic arriving at the public IPv4 to your windows box's private IPv4.

Have you tried pinging something like ipv6.google.com?

When I do this (ping ipv6.google.com) I get the following error:

"Ping request could not find host ipv6.google.com. Please check the name and try again."

What are you using for your network firewall/NAT?  If possible configure a protocol forward NAT entry on this device, forwarding any IP protocol 41 traffic arriving at the public IPv4 to your windows box's private IPv4.

On this machine, I have BitDefender Total Security 2010 as firewall. I have no access to any settings outside of my windows box, so I don't think I can set up such a forwarding of traffic.
