Windows 7: duplicate name exists on the network!!
« on: November 12, 2010, 10:42:37 AM »

Hello!

I have a problem with Hurricane tunnel. Before I used gogoclient but recently connecting is a problem. With Vista I used Sixxs which worked fine (but hard with Windows 7 I understand). That's why I started with Hurricane tunnel. Have Windows 7 64 bits with still installed gogoclient. I have a static IP behind a router. I use the internal IP.

netsh interface ipv6 add address IP6Tunnel 2001:470:1f14:d90::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f14:d90::1

Results in:


Somehow there is an duplicate name. My computers in my workgroup have different names so that's not the problem. Any suggestions??

Thanks

Did you see

http://www.tunnelbroker.net/forums/index.php?topic=1081.0

Or from

http://www.tunnelbroker.net/forums/index.php?topic=438.0

So for the other people with this problem:

-First delete the interface you created (with the command netsh interface ipv6 add v6v4tunnel IP6Tunnel [public ip] 216.66.22.2):
netsh interface ipv6 delete interface IP6Tunnel

-and then start over again but use your local ip:
netsh interface ipv6 add v6v4tunnel IP6Tunnel [local ip] 216.66.22.2

Thanks for your quick reply :) :). Looked at several other posts but could not work it out due to a lake of understanding of netsh commands. Tried to delete the tunnel but did not work.

Now I succeeded but the two second messages remain: "The object already exists". How to delete them first also?

Can I have Hurricane tunnel and gogoclient next to each other or even have both running?

You can only have one adapter named IP6Tunnel, and I think I remember reading somewhere that the adapter has to be called that for the HE stuff to work

If this is 64bit, make sure you use:

interface=IP6Tunnel

on that first line. For some reason 64bit requires that format and 32bit doesn't (but it works on 32bit).

Done; still does not work ipv6. The two second messages remain: "The object already exists".

Try a full IPv6 reset with:

netsh int ipv6 reset

(might need a reboot). That should clear out any duplicate interfaces.

Thanks. Did a reset and a delete and then the batch file as admin. No errors but still no ipv6 :-[
Any other advise or how to analyze the problem?

Probably need to stop using the gogo6 tunnel at the same time, which is also not reachable:

Code: [Select]
~$ ping6 2001:5c0:1400:b::8741
PING 2001:5c0:1400:b::8741(2001:5c0:1400:b::8741) 56 data bytes

From 2001:4de0:1000:a22::1 icmp_seq=2 Time exceeded: Hop limit
^C

i would agree.  you will also want to assign an ipv6 address from your routed /64 or /48 to your lan adapter

I belief it works: I have 2001:5c0:1400:b::8741 as my ipv6. :)

Gogo6 is reachable but not all the time that's why I want to change to Hurricane.

I do not understand this.

the address you gave is a gogo6 address, not HE.

on your tunnel detail page, there are listings for a bunch of things.  one of those things says routed /64 (or something close)  you need to ssign an address from that subnet to your lan connection.  so, if your /64 was 2001:db8:1234:1::/64, you could assign 2001:db8:1234:1:1 to your lan connection

Oh that's a good one; I'm still on the gogo6 and not on HE.

How do I manage to assign the address. Do I need to do that in my Zyxel modem? What are the exact details?
