Dear Fabian,You will be comfortable using the Cisco ASR 1000 Series routers, which includes the stateful NAT64 technology. In the other hand this mailing list is not appropriate for a quick answer or comment on this issue. Rather move  this point to the AFNOG mailing list, this one regroups the operators and ISP engineers who can quickly send some suitable comments or best pratices on NAT64 with Cisco2921. I copied  here the afnog mailing list.

We are looking into way we can gradually deploy IPv6 in our network…

Already we have it running and we have one Test Machine……. The challenge we are facing is that from that machine with IPv6 and from other Machines with IPv4 we can’t communicate in either direction..

IPv6 Machine just communicate with IPv6 only machines like wise IPv4 Machines just communicate with IPv4 machines ….

A work around is to do NAT64 between the two subnets….

It seems the hardware (Cisco 2921 router with IOS Version 15.0) can’t do NAT64……..

>From the internet it seems NAT64 runs on IOS-XE and IOS-CGSE which are Hardware dependent……..seems that we can’t upgrade IOS Version 15.0 to any the two which supports NAT64.

Before committing any expenses to acquire new router we want to reach out to the community for comments and advises….

Pls. review and advise.

Thank you…
