NAT
Network Address Translation (NAT) translates an IP address in the IP packet header to another IP
address. Typically, NAT is configured on gateways to enable private hosts to access external
networks and external hosts to access private network resources such as a Web server.
Use this feature in routing mode. In the initial configuration, the quick wizard in routing mode
automatically generates a NAT policy to ensure internal-to-external access. You can directly use the
NAT policy, or configure different NAT policies based on the network requirements.
