4.3.3 NAT
The NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host
in a packet. The default setting is Dynamic NAT. 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.
Virtual Circuit: VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual
circuit. There are eight groups of PVC can be defined and used.
NAT Status: Show the NAT status, Activated or Deactivated.
Number of IPs: Users can select Single or Multiple. Select Multiple to trigger IP Address Mapping.
