I'm trying to do some tests with ipv6 + nat-pt at the moment. I got most of that stuff running - except nat-pt.
Perhaps, you can give me an answer, if my basic approach is possible at all...
I'm using a 2621XM, running IOS 12.3 (c2600-advipservicesk9-mz.123-26.bin).
On my router, I configured 2 FastEthernet Interfaces + 1 Tunnel Interface:
no ip address
no ip redirects
ipv6 address 2002:4410:4483:1::/64 eui-64
tunnel source FastEthernet0/0
tunnel mode ipv6ip isatap
ip address 192.168.100.1 255.255.255.0
ipv6 address FD00:4410:4483:64::1/64
ip address 10.10.10.2 255.255.255.0
As you can see above, I'm running an isatap infrastructure. Is it possible, to use nat-pt, so that external Clients, who are not part of my lan, use my 2621XM as nat-pt device? Or is it impossible to use nat-pt together with isatap?
