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 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.
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.
Number of IPs : User can select Single or Multiple.
