NAT
The NAT Configuration page allows users to set the configuration for the Network
Address Translation. The default setting is Dynamic NAPT. It provides dynamic Network
Address Translation capability between LAN and multiple WAN connections, and the
LAN traffic is routed to appropriate WAN connections based on the destination IP
address and Route Table. This eliminates the need for the static NAT session
configuration between multiple LAN clients and multiple WAN connections.
When the Dynamic NAPT is chosen, there is no need to configure the NAT Session and
NAT Session Name Configuration.
The NAT option only maps single WAN IP address to the local PC IP address. It is peer-
to-peer mapping. (1x1) For each WAN interface, only one local PC IP address can be
associated with each WAN interface. Click the link Session Name Configuration to add
the session name for WAN interface.
The NAPT option only maps single WAN IP address to many local PCs IP address. (1xN).
It is the multiple-mapping mechanism. For each WAN Interface, more than one local
PC can be associated with one WAN Interface. Click the link Session Name
Configuration to add the session name for WAN interface.
