Carrier Grade NAT (CGNAT) allows service providers to leverage existing IPv4 infrastructure by mitigating IPv4 address exhaustion while providing an easy migration path to IPv6 infrastructure that is seamless to subscribers and users. CGNAT support large-scale, carrier deployment by extending IPv4 address translations while supporting translation from IPv4 address to IPv6 address and from IPv6 to IPv4.

As service providers and enterprises already use firewalls as the first line of defense in network security to monitor and block incoming and outgoing network traffic for and from threats, the deployment of Hillstone CGNAT solution is simple as it is just configurations of Hillstone next-generation firewalls (NGFWs) for CGNAT and NAT functions using Hillstone StoneOS, the operating system for Hillstone NGFWs.
