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.
