Question
What is the PAN-OS NPTv6 feature based on RFC 6296 used for?
A. Application port number translation
B. IPv6-to-IPv6 network prefix translation
C. Stateful translation to provide better security
D. IPv6-to-IPv6 host portion translation
Answer
B. IPv6-to-IPv6 network prefix translation
Explanation
The PAN-OS NPTv6 feature, based on RFC 6296, is used for IPv6-to-IPv6 network prefix translation. This feature performs stateless translation of one IPv6 prefix to another. It does not keep track of ports or sessions on the addresses translated. This differentiates it from NAT66, which is stateful. The host portion of an IPv6 address is simply copied and remains the same on either side of the firewall. Therefore, the correct answer is B. IPv6-to-IPv6 network prefix translation.
