I'm looking for NAT-PT in pfsense. I have IPv6 WAN Address. One of my Application only supports IPv4.
WAN (ipv6) –-------> NAT-PT --------> LAN (ipv4)
Since a few years Cisco have implement this options in their products.
Is there also a option in pfsense?
PS: Maybe BIS is working in pfsense ?
There is no NAT between IPv4 and IPv6 in pfSense (yet?), it doesn't work that way.
NAT64 allows an IPv6 only client to reach an IPv4 server . There exists an implementation for OpenBSD  but probably not yet for FreeBSD. If I remember correctly the targeted version was once FreeBSD 9, but Ermal might know better as he is/was involved [3,4].
