You can enhance the efficiency of Network Address Translation (NAT) IPv6 translations on SRX Series Firewalls by offloading these tasks to the network processing unit (NPU). This includes handling IPv6 to IPv4, IPv4 to IPv6, and IPv6 to IPv6 translations. Offloading these processes to the NPU decreases the CPU load on the SPU, resulting in improved performance for NAT data packet processing. Consequently, this optimizes the handling of non-ALG traffic and ensures seamless communication between IPv4 and IPv6 networks.
