6.4 NAT Configuration
The NAT Configuration page allows the user 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 addresses 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 NAPT option maps the single WAN IP addresses to many local PCs IP addresses.
(1xN). It is the multiple-mapping mechanism. For each WAN Interface, more than one
local PCs can be associated with one WAN Interface. Click the link
