Vista+Linksys WRT54G router=no IPv6 tunnel connectivity

[a1pcfixer]

I'm running Vista Ultimate behind a Linksys WRT54G ver 2.0 router, and running
Norton Security Suite.

After registering at tunnelbroker.net and obtaining tunnel settings there,
I followed the directions under "IPv6 Tunnel Configurations by OS (Vista)"

As far as I can tell, in Norton Security Suite I'm good to go;

"The Automatic Learn IPv6 NAT Traversal Traffic option is available
only when Automatic Program Control is on. By default, Automatic Learn
IPv6 NAT Traversal Traffic is turned on. In this case, Norton Security
Suite allows all IPv6 NAT Traversal traffic."

Problem is (I think), my Linksys router doesn't seem to be allowing such traffic;

Firefox can't find the server at ipv6.google.com.

My Linksys WRT54GS ver 2.0 has v4.71.1, Hyperwrt 2.1b1 +
Thibor15c [May 12 2006] firmware. That router cannot filter by "protocol",
only "port". The poor router knows only about TCP and UDP.

I've seen it mentioned in these forums about using the routers DMZ, but
I've set my DMZ in my router to a high IP on my LAN so unsolicited packets
get dropped (for security), and I'd rather not go that route unless
absolutely needed.

So, with my VERY limited knowledge of all of this, how do I get this working?

[cholzhauer]

Well, is whatever you're using for DNS returning a IPv6 address?

Also note that in Windows, you NEED to assign your Local Area Connection an IPv6 address to browse the web.

Q1; I'm uncertain, as I'm not sure any such requests are even leaving my PC/router.

My router is setup with the following 3 DNS;

204.117.214.10
204.97.212.10
4.2.2.4

Q2; In Vista under properties for my Lan connection in Control Panel, settings for
"Internet Protocol Version 6 (TCP/IPv6)" are all set to automatic. I assumed such worked automatically.

If I knew how to set that up to manually assign a specific IPv6 address I would.
Network settings for TCP/IPv4 I understood, but this newer TCP/IPv6 has me a bit confused.

Some of my HE tunnel settings are;

Server IPv4 address:     209.51.181.2
   Server IPv6 address:    2001:470:1f10:435::1/64
   Client IPv4 address:    204.117.214.10
   Client IPv6 address:    2001:470:1f10:435::2/64
Available DNS Resolvers
   Anycasted IPv6 Caching Nameserver:    2001:470:20::2
   Anycasted IPv4 Caching Nameserver:    74.82.42.42

So, out of those settings, what exactly do I set in my Local Area Connection TCP/IPv6?

Please excuse my ignorance on this.

Let's assign an address first.

It sounds like you're not doing RA or DHCP, so we'll manually assign address.  You will need do double check this address, as this is only a guess.  On your tunnel page, there's a line for routed /64...I assume that is something like 2001:470:1f11:435::/64 ?

I assume you know how to add a static v4 address to your adapter.  To add a static v6 address, you go through the same steps (control panel, networking, ect) except instead of opening the properties on the TCPIPv4, open properties on TCPIPv6.  Enter in a static v6 address from your routed /64, for example 2001:470:1f11:435::2. 

After you've done that, can you post the output of "ipconfig /all" and "netstat -nr" ?

I assigned it; 2001:470:1f11:435::2
It then stated I also needed a subnet mask(?), I clicked on OK, and it auto-assigned it to 64 (hope that's good).

[a1pcfixer]

Did you could check that 2001:470:1f11:435::/64 is your routed /64 ?  (Check on the Tunnel details page)

Yes.

Something isn't working (obviously)  Did you use 192.168.1.106 as your IP address when you created your tunnel?  (That is, you took the commands HE gave you and substituted 192.168.1.106 as your side of the tunnel)

Are you referring to..... 

IPv4 endpoint:
(your side of the tunnel)

....if yes, I'm not certain.

Should I create a new tunnel and start all over?

[a1pcfixer]

IPv4 endpoint:
(your side of the tunnel)

Yep.  HE would have filled in whatever public address it saw your traffic coming from eg, 12.34.56.78 and not 192.168.1.106.

Deleting the tunnel and starting over would probably help.

On Create a Regular Tunnel/setup page I entered  192.168.1.106  into "IPv4 endpoint:(your side of the tunnel)", and hit Submit. It came back with "Error: That IPv4 endpoint has been blocked (RFC1918 Private Address Space)"

The following is what the HE "Setup Regular IPv6 Tunnel" page shows me........

IPv4 endpoint:
(your side of the tunnel)    
You are viewing from IP:    67.167.109.154
We recommend you use:    
Chicago, IL [ 209.51.181.2 ]
Which Server Is Closest to you?:

[a1pcfixer]

Right.

You need to leave the webpage fill in whatever values it wants (67.167.109.154)

You don't need to delete and re-create the tunnel on the webpages, but if you have already deleted it, we'll need to re-create it.

I deleted it, and then recreated another. I think THAT (IPv4 endpoint) is where my troubles start.
My IP on the web shows as [67.167.109.154]. My IP behind my router is [192.168.1.106]

If I enter either of those into........

IPv4 endpoint:
(your side of the tunnel)   

...it comes back with errors;

[192.168.1.106]..........
Error: That IPv4 endpoint has been blocked (RFC1918 Private Address Space)

[67.167.109.154]..........
Error: Your IPv4 endpoint is unreachable or unstable. Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 66.220.2.74 through your firewall.

I currently have Norton Secuity Suite's firewall disabled, so my Linksys WRT54G router must be a part of this mess.

I used one of my 3 DNS server IP's to create a tunnel, which I'm guessing is wrong.

[a1pcfixer]

As you've found out, you can't use 192.168.0.0/16 or 10.0.0.0/8 ect.

You NEED to use your 64.167.109.154 address that HE detects.

As you've also found you, your system needs to reply to Ping requests for any of this to work. 

I've managed to disable enough things on the router to get HE to allow me to setup another tunnel with
[64.167.109.154]. That's a small bit of progress! (hoping I'm not exposed now).

Altering the recommended commands as you suggested.........

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.1.106 209.51.181.2
netsh interface ipv6 add address IP6Tunnel 2001:470:1f10:91e::2

Ok.
