Hi GS,

I configure NAT-PT as follow:


Your problem may be that the target router, the router with ip address 172.16.1.2, is getting encapsulation failure when it tries to reply to the virtual IPv4 address, 172.16.1.20. You can test this by running "debug ip packet". With both static and dynamic NAT-PT it is common for the translating router NOT to reply to arps to the virtual IPv4 address. Try a static arp on the target router to the virtual IPv4 address. For example:

arp 172.16.1.20 0011.2222.3333 arpa

Netmasterclass offers a Class on Demand on IPv6 that covers both static and dynamic NAT-PT.
