When the IP that has to be translated is an IPv6 address, Persistent NAT is not supported.
Also to explain the usage of max. session number with persistent NAT, maximum number of sessions which can be allowed through any single persistent NAT binding. So here, with this configuration, you can limit the number of sessions used by a single persistent NAT binding but not the total number of NAT sessions even for IPv4.
Previously, the maximum number of sessions allowed for a persistent NAT binding was 100. This limit is now 65,536. One can now configure the maximum number of sessions ranging from 8 through 65,536.
Hope this helps.
Thanks,
Pradeep
