Hi there,

Stateful NAT64 is only supported on ISR4300/4500 and ASR/CSR1000 routers.

cheers,

Seb.

Hi Seb,

Thanks for your quick response.

I have done some research & found ASA with 9.1.1 will help me achieving the same.

Cheers,

Hi Parmanand,

You are right the ASA does support NAT64, but it is stateless. For each IPv6 address you will need a corresponding IPv4 address. You will likely need a large pool of private IPv4 addresses to NAT into, these in turn, if requiring internet access, will then need to undergo stateful IPv4 NAT. NAT'ing traffic twice will require a little bit more effort to audit.

cheers,

Seb.
