Win7 Tunnel stopped working after new computer
« on: June 29, 2013, 01:47:36 PM »

So I recently got a new desktop.  On my old one, my ipv6 tunnel worked fine.  It'd been a while since I made it, though, so I've forgotten the exact steps.

Now on my new desktop, the tunnel doesn't seem to work.  Can't ping any ipv6 sites, can't access them, anything.

I deleted and recreated the tunnel on HE's side, just in case.  I can't for the life of me figure out how to completely delete the tunnel information in netsh, as when I try to add the info again I just get the "duplicate name exists on the network" error and I can't figure out how to delete anything beyond the interface itself (and when I re-add the interface, the routes and addresses seem to come back from before.).

Here's my ipconfig /all:

Code: [Select]

What commands did you use to create the tunnel? 

Code: [Select]
netsh interface ipv6 delete interface IP6Tunnel

I just used the commands given on the 'Example Configurations' page.  I can paste them if you need.

Yes, please.  If you didn't change them to reflect your nat address, it won't work

Code: [Select]
netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 108.3.147.249 216.66.22.2
netsh interface ipv6 add address IP6Tunnel 2001:470:7:278::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:7:278::1

Here.  My IP's correct.  Beyond that, I'm lost.

My IP's correct.
It does not look correct to me. Your earlier post suggested your IP was 192.168.1.42.

In addition to changing the IP in the tunnel specification on the computer, you may also need to update the configuration on your router. If your router handles protocol 41 automatically, you may not need to change the configuration. But if your router need explicit configuration of the forwarding, you may need to update to reflect the IP of the new computer.

That (the .42 IP) is the internal IP.  Do I need to change the given config lines to use my internal IP?

Also, I don't remember having to fiddle with my router when I set it up last time.  I did just find http://bill-owens.blogspot.com/2011/11/hurricane-electric-ipv6-tunnel-through.html.  Would that do it?  I definitely didn't do this last time and it worked...

Yes, you need to change the public IP address given to you by HE to your private 192.168.x.x address.

Ah, that seems to have worked perfectly.  Thanks so much!
