IPv6 NAT-PT

Hethe

Hi, I have been a long time lurker and really enjoy reading the forums. I am just learning IPv6 and thought I would try and set it up in my home. I am having an issue getting NAT-PT to work on my 3640. My host computer is Windows Vista SP1. Vista is automatically getting the correct IP address. I am able to ping the gateway which is f3/1.2 on the 3640. That interface is connected to my 2924 and the vista machine is connected to the 2924 on a port that is apart of vlan 2. I am unable to ping any IPv4 addresses and nothing is showing up in my IPv6 nat translation. I ran a debug on the translation and getting no information back. Windows Vista is giving me the "error code 1231" when trying to ping out to an IPv4 address. I am guessing that my ipv4 pings are not even reaching the router. Also vista is not getting my DNS server that I setup in my DHCP pool. Any help would be appreciated.

Can you ping 4.2.2.1 from R1?

What does your routing table on R1 look like? Default route?

Have you replaced Vista with a know working operating system like XP or Linux?

This is a home setup right? Have you debugged the ip packets to see if anything is getting sent to R1, rather then just guessing (even if its a good guess since it is Vista ) that its not making it off the Vista PC.

The IP V4 address your PC has is the default address it gives itself if it can't find a DHCP server on the network. Same with XP.

Check your DHCP settings or statically set it.
