NAT (Network Address Translation) is a method of mapping one or more IP addresses
and/or service ports into different specified services. It allows the internal IP addresses of
many computers on a LAN to be translated to one public address to save costs and resources
of multiple public IP addresses. It also plays a security role by obscuring the true IP
addresses of important machines from potential hackers on the Internet. The Vigor 3900
Series is NAT-enabled by default and gets one globally routable IP addresses from the ISP
by Static, PPPoE, or DHCP mechanism. The Vigor300B assigns private network IP
addresses according to RFC-1918 protocol and translates the private network addresses to a
globally routable IP address so that local hosts can communicate with the router and access
the Internet.
