We've deployed some ASR1006's for NAT44 and NAT64. The NAT44 is for our IPTv VoD service (Unicast), while the NAT64 is for IPv6-only customers trying to reach IPv4-only resources. We have the same chassis playing both roles. I don't know about the ASA, but the ASR1000 does support Stateful Inter-Chassis NAT Redundancy, but only for NAT44 at this time. Not sure when NAT64 will be coming, but I'm sure it will. Also, I think the ESP20 should be good for about 2,000,000 NAT translations last time I checked. Of course, the ASR1006 makes lots of sense for us because it's also a router, so we can still IP/MPLS stuff on there without any restrictions. Hope this helps. Cheers, Mark.
