Hello Andreas,

In general performance of NAT64 is not really high. I remember on Cisco
2801 ~4Mbit was all I could get. I used one of the latest 12.4T release,
12.4(24)T as far as I remember. The smaller reasonable device to play
with would be Cisco 1841 but it's also available on 870 and 880
platform. Of course for the production network I'd check how much
traffic it's going to handle (and not only in number of TCP sessions
that have to be translated but throughput itself, because NAT64 is
process switched since 12.4(20)T, until that it was fast switched).

Regards,
