6.8.1 Mapped IP
Internal private IP addresses are translated through NAT (Network Address Translation). If a server is located
in the LAN network, it has a private IP address, and outside users cannot connect directly to LAN servers’
private IP address. To connect to a LAN network server, outside users have to first connect to a real IP
address of the WAN network, and the real IP is translated to a private IP of the LAN network. Mapped IP and
Virtual Server are the two methods to translate the real IP into private IP. Mapped IP maps IP in one-to-one
way; that means all services of one real WAN IP address is mapped to one private LAN IP address.
