PPP, PPP Configuration Parameters

NAT Configuration Group

NAT: Enable or disable NAT (Network Address Translation). The default is Enable.

Note: For routing to take effect, enable then save the configuration.

Enabling NAT

Your LAN can use one set of IP addresses for internal traffic and a second set of addresses for external traffic. The

router with NAT does the simple IP routing between the LAN interface and the WAN interface. NAT hides the LAN

address behind a single IP address on the wireless side.

Your internal addresses are shielded from the public Internet.
