I've got a 1001-x and per cisco it can support up to 2m NAT connections. I see the following license feature:
Index 22 Feature: nat64_stateful_2m
I guess my question is, do I have to have this license to do 2 million 4to4 NAT connections? It doesn't look like I need it to do NAT mode CGN. I've got my NAT configured as such.
