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.
• NAT (Static): 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.
Session Name: This field allows the user to enter his/her own session Name to
distinguish different NAT session for different interfaces among different PPP
sessions and different PVCs.
