I'm just not sure what part of the config I am doing wrong or there is some bug i am running into. I am running c3725-advipservicesk9-mz.124-15.T9.bin.
The following is the config i have on the router.
interface Tunnel10

What part am I doing wrong? Is there a better IOS I should be using? What address should I use to ping6?

Hi,
I'm also using VB ;-)
Here is what I have when my router is off:

Once my router is ON:

Ok.

You can run debug ipv6 icmp and debug ipv6 packet to track the RA and RS:

I guess I should ask, has anyone done ISATAP from Windows XP? How?
Thanks,

Hi Greg,
Can you ping 10.156.68.40 from your station ?
Your tunnel configuration looks good.
I did the same configuration on my laptop (XR SP2) and it's working fine.

Yes, I have no problem doing ping and telnet to the router. Out of curiosity,
what router model and IOS version are you using?
I am trying on:
Cisco 3725
c3725-advipservicesk9-mz.124-15.T9.bin
Now to be specific, My XP SP3 is running in Virtual box while I test this setup. Maybe SP3 has issues.
Thanks,
Greg

Related to above, how can I tell if it works? How do I test it?

Thanks. Moving from a 3725 running c3725-advipservicesk9-mz.124-15.T9.bin to a 7200 running c7200-adventerprisek9-mz.122-33.SRC.bin made it all work.
Thanks,
