Cannot ping with IPv6

[Alex]

Hi,

I'm running Windows Vista Ultimate with IPv6 and Teredo installed and
enabled, but it seems I

am unable to ping any hosts on the local network (which consists of one
other XP SP3 machine)

or internet. Both computers are connected to a standard router (Dell
TrueMobile 2300, which is

IPv4 only I believe). Still, an IPv4 router should not matter considering
Teredo should be

enabled on both computers.

Running ipconfig returns the following:

Here is what some of the ping commands returned. (I do not have much of an
understanding of

IPv6, so I may be giving a bad address to ping some of the time.)

Pings to all other addresses with/without zone IDs have similar results.

A ping to any of the sites listed on http://www.ipv6.org/v6-www.html from
Vista returns:

try again.

And on XP something like:

----------------------------------------------------------------

No surprise, I also can't view any of the sites from IE7/Firefox.
I'll be glad to provide any other info that is needed to diagnose the problem.

Thanks.

Ok, I've resolve everything on Vista now. I can access several IPv6 websites
(not sure why only a few, but I'm assuming it's simply because of the Teredo
server). On XP I'm having the same problems: Request timed out.

Hi Alex,

So what was your solution?

Aaron

 

[Alex]

Firstly I ran (in PowerShell):
netsh interface ipv6 teredo show state

This gave me information on the state of Teredo (which was inactive because
of an error). I re-enabled Teredo using the disable/set commands with the
entrepriseclient option, followed by:
netsh interface ipv6 reset

After a restart (not sure this was necessary) everything seemed to work
fairly well. I could ping IPv6 servers and view IPv6 websites (only some
however, but I believe this limitation is due to the MS Teredo server).

I later found out that it is impossible to get it working on XP with my
network configuration, since my router has a symmetric NAT and the version of
Teredo for XP does not support symmetric NATs (Vista has partial support for
symmetric NATs).

Not sure how common this problem is, but I only found it documented
(inconclusively) on one web page after much searching. Hopefully this
solution will help some of you trying to get IPv6 working on Vista...
