Network Address Translation
(NAT)
NAT (Network Address Translation) translates multiple IP Address on the private LAN to one global(public) address that is snet out to the Internet. As a result, this is also called "a nature firewall" since the addresses of the PCs on this private LAN will not be transmitted on the Internet.
NAT Local Address Range Pool
This section is for dynamic assignment only. "Base Address"
defines the starting address for the local (private) IP address from that NAT
will take force. "Count" determines the size of this pool starting
from the base address.
NAT Global Address Range Pool
This section is for dynamic assignment only. "Base Address"
defines the starting address for the global IP address from which the Router
will select and assign to the requested Global IP addresses. "Count"
determines the size of this pool starting from the base address. "Interface"
specifies through what kind of interface the IP addresses of this pool will
go out.
Fixed NAT Mapping
This section is for fixed assignment only. "Local Address" defines
the local (private) IP address. "Global Address" defines the global
IP address which the Router will assign to the corresponding local IP addresses.
"Interface" specifies through what kind of interface the packets for
a private host will go out.
